Red Hat SummitVersion 3 REST API Guide
Red Hat Virtualization 4.0
Using the Red Hat Virtualization Version 3 REST Application Programming Interface
Abstract
Version 4 of the Red Hat Virtualization Manager supports versions 3 and 4 of the Representational State Transfer API. The information and examples in this guide apply to version 3 of the REST API.
Chapter 1. Introduction
Red Hat Virtualization Manager provides a Representational State Transfer (REST) API. The API provides software developers and system administrators with control over their Red Hat Virtualization environment outside of the standard web interface. The REST API is useful for developers and administrators who aim to integrate the functionality of a Red Hat Virtualization environment with custom scripts or external applications that access the API via the standard Hypertext Transfer Protocol (HTTP).
The benefits of the REST API are:
- Broad client support - Any programming language, framework, or system with support for HTTP protocol can use the API;
- Self descriptive - Client applications require minimal knowledge of the virtualization infrastructure as many details are discovered at runtime;
- Resource-based model - The resource-based REST model provides a natural way to manage a virtualization platform.
This provides developers and administrators with the ability to:
- Integrate with enterprise IT systems.
- Integrate with third-party virtualization software.
- Perform automated maintenance or error checking tasks.
- Automate repetitive tasks in a Red Hat Virtualization environment with scripts.
This documentation acts as a reference to the Red Hat Virtualization Manager REST API. It aims to provide developers and administrators with instructions and examples to help harness the functionality of their Red Hat Virtualization environment through the REST API either directly or using the provided Python libraries.
1.1. Representational State Transfer
Representational State Transfer (REST) is a design architecture that focuses on resources for a specific service and their representations. A resource representation is a key abstraction of information that corresponds to one specific managed element on a server. A client sends a request to a server element located at a Uniform Resource Identifier (URI) and performs operations with standard HTTP methods, such as
GET, POST, PUT, and DELETE. This provides a stateless communication between the client and server where each request acts independent of any other request and contains all necessary information to complete the request.
1.2. Red Hat Virtualization REST API Prerequisites
Red Hat Virtualization REST API Prerequisites
- A networked installation of Red Hat Virtualization Manager, which includes the REST API.
- A client or programming library that initiates and receives HTTP requests from the REST API. For example:
- Python software development kit (SDK)
- Java software development kit (SDK)
- cURL command line tool
- RESTClient, a debugger for RESTful web services
- Knowledge of Hypertext Transfer Protocol (HTTP), which is the protocol used for REST API interactions. The Internet Engineering Task Force provides a Request for Comments (RFC) explaining the Hypertext Transfer Protocol at http://www.ietf.org/rfc/rfc2616.txt.
- Knowledge of Extensible Markup Language (XML) or JavaScript Object Notation (JSON), which the API uses to construct resource representations. The W3C provides a full specification on XML at http://www.w3.org/TR/xml/. ECMA International provide a free publication on JSON at http://www.ecma-international.org.
Chapter 2. Authentication and Security
2.1. TLS/SSL Certification
The Red Hat Virtualization Manager API requires Hypertext Transfer Protocol Secure (HTTPS) [1] for secure interaction with client software, such as the Manager's SDK and CLI components. This involves a process of obtaining a certificate from the Red Hat Virtualization Manager and importing it into the certificate store of your client.
Important
Obtain your certificate from the Red Hat Virtualization Manager using a secure network connection.
Procedure 2.1. Obtaining a Certificate
You can obtain a certificate from the Red Hat Virtualization Manager and transfer it to the client machine using one of three methods:
- Method 1 - Use a command line tool to download the certificate from the Manager. Examples of command line tools include cURL and Wget, both of which are available on multiple platforms.
- If using cURL:
$ curl -o rhvm.cer http://[manager-fqdn]/ovirt-engine/services/pki-resource?resource=ca-certificate&format=X509-PEM-CA
- If using Wget:
$ wget -O rhvm.cer http://[manager-fqdn]/ovirt-engine/services/pki-resource?resource=ca-certificate&format=X509-PEM-CA
- Method 2 - Use a web browser to navigate to the certificate located at:
http://[manager-fqdn]/ovirt-engine/services/pki-resource?resource=ca-certificate&format=X509-PEM-CA
Depending on the chosen browser, the certificate either downloads or imports into the browser's keystore.- If the browser downloads the certificate: save the file as
rhvm.cer.If the browser imports the certificate: export it from the browser's certification options and save it asrhvm.cer.
- Method 3 - Log in to the Manager, export the certificate from the truststore and copy it to your client machine.
- Log in to the Manager as the
rootuser. - Export the certificate from the truststore using the Java keytool management utility:
$ keytool -exportcert -keystore /etc/pki/ovirt-engine/.truststore -alias cacert -storepass mypass -file rhvm.cer
This creates a certificate file calledrhvm.cer. - Copy the certificate to the client machine using the
scpcommand:$ scp rhvm.cer [username]@[client-machine]:[directory]
Each of these methods results in a certificate file named
rhvm.cer on your client machine. An API user imports this file into the certificate store of the client.
Procedure 2.2. Importing a Certificate to a Client
- Importing a certificate to a client relies on how the client itself stores and interprets certificates. This guide contains some examples on importing certificates. For clients not using Network Security Services (NSS) or Java KeyStore (JKS), see your client documentation for more information on importing a certificate.
2.2. HTTP Authentication
Any user with a Red Hat Virtualization account has access to the REST API. An API user submits a mandatory Red Hat Virtualization Manager user name and password with all requests to the API. Each request uses HTTP Basic Authentication [2] to encode these credentials. If a request does not include an appropriate
Authorization header, the API sends a 401 Authorization Required as a result:
Example 2.1. Access to the REST API without appropriate credentials
HEAD [base] HTTP/1.1 Host: [host] HTTP/1.1 401 Authorization Required
Request are issued with an
Authorization header for the specified realm. An API user encodes an appropriate Red Hat Virtualization Manager domain and user in the supplied credentials with the username@domain:password convention.
The following table shows the process for encoding credentials in base64.
| Item | Value |
|---|---|
| username | rhevmadmin |
| domain | domain.example.com |
| password | 123456 |
| unencoded credentials | rhevmadmin@domain.example.com:123456 |
| base64 encoded credentials | cmhldm1hZG1pbkBibGFjay5xdW1yYW5ldC5jb206MTIzNDU2 |
An API user provides the base64 encoded credentials as shown:
Example 2.2. Access to the REST API with appropriate credentials
HEAD [base] HTTP/1.1 Host: [host] Authorization: Basic cmhldm1hZG1pbkBibGFjay5xdW1yYW5ldC5jb206MTIzNDU2 HTTP/1.1 200 OK ...
Important
Basic authentication involves potentially sensitive information, such as passwords, sent as plain text. REST API requires Hypertext Transfer Protocol Secure (HTTPS) for transport-level encryption of plain-text requests.
Important
Some base64 libraries break the result into multiple lines and terminate each line with a newline character. This breaks the header and causes a faulty request. The Authorization header requires the encoded credentials on a single line within the header.
2.3. Authentication Sessions
The API also provides the ability for authentication session support. An API user sends an initial request with authentication details, then sends all subsequent requests using a session cookie to authenticate. The following procedure demonstrates how to use an authenticated session.
Procedure 2.3. Requesting an authenticated session
- Send a request with the
AuthorizationandPrefer: persistent-authHEAD [base] HTTP/1.1 Host: [host] Authorization: Basic cmhldm1hZG1pbkBibGFjay5xdW1yYW5ldC5jb206MTIzNDU2 Prefer: persistent-auth HTTP/1.1 200 OK ...
This returns a response with the following header:Set-Cookie: JSESSIONID=5dQja5ubr4yvI2MM2z+LZxrK; Path=/ovirt-engine/api; Secure
Note theJSESSIONID=value. In this example the value isJSESSIONID=5dQja5ubr4yvI2MM2z+LZxrK. - Send all subsequent requests with the
Prefer: persistent-authandcookieheader with theJSESSIONID=value. TheAuthorizationis no longer needed when using an authenticated session.HEAD [base] HTTP/1.1 Host: [host] Prefer: persistent-auth cookie: JSESSIONID=5dQja5ubr4yvI2MM2z+LZxrK HTTP/1.1 200 OK ...
- When the session is no longer required, perform a request to the sever without the
Prefer: persistent-authheader.HEAD [base] HTTP/1.1 Host: [host] Authorization: Basic cmhldm1hZG1pbkBibGFjay5xdW1yYW5ldC5jb206MTIzNDU2 HTTP/1.1 200 OK ...
[1]
HTTPS is described in RFC 2818 HTTP Over TLS.
[2]
Basic Authentication is described in RFC 2617 HTTP Authentication: Basic and Digest Access Authentication.
Chapter 3. REST API Quick Start Example
This chapter provides an example to demonstrate the REST API's ability to setup a basic Red Hat Virtualization environment and create a virtual machine.
In addition to the standard prerequisites, this example requires the following:
- A networked and configured Red Hat Virtualization Host;
- An ISO file containing a desired virtual machine operating system to install. This chapter uses Red Hat Enterprise Linux Server 6 for our installation ISO example; and
- Red Hat Virtualization's engine-iso-uploader tool to upload your chosen operating system ISO file.
This example uses cURL to demonstrate REST requests with a client application. Note that any application capable of HTTP requests can substitute for cURL.
Important
For simplicity, the HTTP request headers in this example omit the
Host: and Authorization: fields. However, these fields are mandatory and require data specific to your installation of Red Hat Virtualization Manager.
Important
All cURL examples include placeholders for authentication details (
USER:PASS) and certificate location (CERT). Ensure all requests performed with cURL fulfill certification and authentication requirements.
Note
Red Hat Virtualization Manager generates a globally unique identifier (GUID) for the
id attribute for each resource. Identifier codes in this example might appear different to the identifier codes in your Red Hat Virtualization environment.
3.1. Example: Access API Entry Point
The following request retrieves a representation of the main entry point for version 3 of the API.

Important
When neither the header nor the URL prefix are used, the server will automatically select a version. The default is version
4. You can change the default version using the ENGINE_API_DEFAULT_VERSION parameter:
# echo "ENGINE_API_DEFAULT_VERSION=3" > \ /etc/ovirt-engine/engine.conf.d/99-set-default-version.conf # systemctl restart ovirt-engine
Changing this parameter affects all users of the Manager that don't specify the version explicitly.
The entry point provides a user with links to the collections in a virtualization environment. The
rel= attribute of each collection link provides a reference point for each link. The next step in this example examines the datacenter collection, which is available through the rel="datacenter" link.
The entry point also contains other data such as
product_info, special_objects and summary. This data is covered in chapters outside this example.
3.2. Example: List Data Center Collection
Red Hat Virtualization Manager creates a
Default data center on installation. This example uses the Default data center as the basis for our virtual environment.
The following request retrieves a representation of the data center collection:
Example 3.2. List data center collection

The data center also contains a link to the
storagedomains sub-collection. The data center uses this sub-collection to attach storage domains from the storagedomains main collection, which this example covers later.
3.3. Example: List Host Cluster Collection
Red Hat Virtualization Manager creates a
Default host cluster on installation. This example uses the Default cluster to group resources in your Red Hat Virtualization environment.
The following request retrieves a representation of the cluster collection:

Note the
id code of your Default host cluster. This code identifies this host cluster in relation to other resources of your virtual environment.
The
Default cluster is associated with the Default data center through a relationship using the id and href attributes of the data_center element.
The
networks sub-collection contains a list of associated network resources for this cluster. The next section examines the networks collection in more detail.
3.4. Example: List Logical Networks Collection
Red Hat Virtualization Manager creates a default
ovirtmgmt network on installation. This network acts as the management network for Red Hat Virtualization Manager to access hosts.
This network is associated with our
Default cluster and is a member of the Default data center. This example uses the ovirtmgmt network to connect our virtual machines.
The following request retrieves a representation of the logical networks collection:
Example 3.4. List logical networks collection

The
ovirtmgmt network is attached to the Default data center through a relationship using the data center's id code.
The
ovirtmgmt network is also attached to the Default cluster through a relationship in the cluster's network sub-collection.
3.5. Example: List Host Collection
This example uses a Red Hat Virtualization Host. Red Hat Virtualization Manager automatically registers any configured Red Hat Virtualization Host. This example retrieves a representation of the hosts collection and shows a Red Hat Virtualization Host named
hypervisor registered with the virtualization environment.

3.7. Example: Create NFS Data Storage
An NFS data storage domain is an exported NFS share attached to a data center and provides storage for virtualized guest images. Creation of a new storage domain requires a
POST request, with the storage domain representation included, sent to the URL of the storage domain collection.
You can enable the wipe after delete option by default on the storage domain. To configure this specify
<wipe_after_delete> in the POST request. This option can be edited after the domain is created, but doing so will not change the wipe after delete property of disks that already exist.
Example 3.7. Create an NFS data storage domain

The
storage_domain element tells the API to store the disk on the data1 storage domain.
3.14. Example: Attach ISO Image to Virtual Machine
The boot media for our example virtual machine requires an CD-ROM or DVD ISO image for an operating system installation. This example uses a Red Hat Enterprise Server 6 ISO image for installation.
ISO images must be available in the
iso1 ISO domain for the virtual machines to use. Red Hat Virtualization Platform provides an uploader tool that ensures that the ISO images are uploaded into the correct directory path with the correct user permissions.
Once the ISO is uploaded, an API user requests the ISO storage domain's
files sub-collection to view the file resource:
Example 3.16. View the files sub-collection in an ISO storage domain
Request:
GET /ovirt-engine/api/storagedomains/00f0d9ce-da15-4b9e-9e3e-3c898fa8b6da/files HTTP/1.1 Accept: application/xml
cURL command:
# curl -X GET -H "Accept: application/xml" -u [USER:PASS] --cacert [CERT] \
https://[RHEVM Host]:443/ovirt-engine/api/storagedomains/00f0d9ce-da15-4b9e-9e3e-3c898fa8b6da/files
The API returns the following representation of the files sub-collection:
<files>
<file id="rhel-server-6.0-x86_64-dvd.iso"
href="/ovirt-engine/api/storagedomains/00f0d9ce-da15-4b9e-9e3e-3c898fa8b6da/

An API user attaches the
rhel-server-6.0-x86_64-dvd.iso to our example virtual machine. Attaching an ISO image is equivalent to using the Change CD button in the Administration or User Portal.
Example 3.17. Attach an ISO image to the virtual machine
Request:
POST /ovirt-engine/api/vms/6efc0cfa-8495-4a96-93e5-ee490328cf48/cdroms HTTP/1.1 Accept: application/xml Content-type: application/xml <cdrom> <file id="rhel-server-6.0-x86_64-dvd.iso"/> </cdrom>
cURL command:
# curl -X POST -H "Accept: application/xml" -H "Content-Type: application/xml" \
-u [USER:PASS] --cacert [CERT] \
-d "<cdrom><file id='rhel-server-6.0-x86_64-dvd.iso'/></cdrom>" \
https://[RHEVM Host]:443/ovirt-engine/api/vms/6efc0cfa-8495-4a96-93e5-ee490328cf48/cdroms
3.15. Example: Start Virtual Machine
The virtual environment is complete and the virtual machine contains all necessary components to function. This example starts the virtual machine using the
start action.
Example 3.18. Start the virtual machine
Request:
POST /ovirt-engine/api/vms/6efc0cfa-8495-4a96-93e5-ee490328cf48/start HTTP/1.1
Accept: application/xml
Content-type: application/xml
<action>
<vm>
<os>
<boot dev="cdrom"/>
</os>
</vm>
</action>
cURL command:
# curl -X POST -H "Accept: application/xml" -H "Content-Type: application/xml" \
-u [USER:PASS] --cacert [CERT] \
-d "<action><vm><os><boot dev='cdrom'/></os></vm></action>" \
https://[RHEVM Host]:443/ovirt-engine/api/vms/6efc0cfa-8495-4a96-93e5-ee490328cf48/start
The additional message entity sets the virtual machine's boot device to CD-ROM for this boot only. This enables the virtual machine to install Red Hat Enterprise Server 6 from the attached ISO image. The boot device reverts back to
disk for all future boots.
3.16. Example: Check System Events
The
start action for the vm1 creates several entries in the events collection. This example lists the events collection and identifies events specific to the API starting a virtual machine.
Example 3.19. List the events collection
Request:
GET /ovirt-engine/api/events HTTP/1.1 Accept: application/xml
cURL command:
# curl -X GET -H "Accept: application/xml" -u [USER:PASS] \

Chapter 4. Entry Point
A user begins interacting with the API through a
GET request on the entry point URI consisting of a host and base.
Example 4.1. Accessing the API Entry Point
If the host is
www.example.com and the base is /ovirt-engine/api, the entry point appears with the following request:
GET /ovirt-engine/api HTTP/1.1
Accept: application/xml
Host: www.example.com
Authorization: [base64 encoded credentials]
HTTP/1.1 200 OK
Content-Type: application/xml
<api>
<link rel="hosts" href="/ovirt-engine/api/hosts"/>
<link rel="vms" href="/ovirt-engine/api/vms"/>
...
<product_info>

<vendor>Red Hat</vendor>
<version revision="0" build="0" minor="0" major="4"/>
</product_info>
<special_objects>
<link rel="templates/blank" href="..."/>
<link rel="tags/root" href="..."/>
</special_objects>
<summary>
<vms>
<total>10</total>
<active>3</active>
</vms>
<hosts>
<total>2</total>
<active>2</active>
</hosts>
<users>

<active>2</active>
</users>
<storage_domains>
<total>2</total>
<active>2</active>
</storage_domains>
</summary>
</ovirt-engine/api>
Note
For simplicity, all other examples omit the
Host: and Authorization: request headers and assume the base is the default /ovirt-engine/api path. This base path differs depending on your implementation.
4.1. Product Information
The entry point contains a
product_info element to help an API user determine the legitimacy of the Red Hat Virtualization environment. This includes the name of the product, the vendor and the version.
Example 4.2. Verify a genuine Red Hat Virtualization environment
The follow elements identify a genuine Red Hat Virtualization 4.0 environment:
<api>
...
<product_info>
<name>Red Hat Virtualization</name>
<vendor>Red Hat</vendor>
<version>
<build>2</build>
<full_version>4.0.2.3-0.1.el7ev</full_version>
<major>4</major>
<minor>0</minor>
<revision>0</revision>
</version>
</product_info>
...
</ovirt-engine/api>
4.2. Link Elements
Access to the Entry Point provides
link elements and URIs for all of the resource collections the API exposes. Each collection uses a relation type to identify the URI a client needs.
| Relationship | Description |
|---|---|
capabilities | Supported capabilities of the Red Hat Virtualization Manager. |
datacenters | Data centers. |
clusters | Host clusters. |
networks | Virtual networks. |
storagedomains | Storage domains. |
hosts | Hosts. |
vms | Virtual machines. |
disks | Virtual disks. |
templates | Templates. |
vmpools | Virtual machine pools. |
domains | Identity service domains. |
groups | Imported identity service groups. |
roles | Roles. |
users | Users. |
tags | Tags. |
events | Events. |
Figure 4.1. The relationship between the API entry point and the resource collections exposed by the API
Note
All URIs shown in example responses are illustrative. The format of all URIs returned by the server is opaque. Clients navigate to specific resources through the entry point URI and use the relationship types to access the URIs.
The server chooses to include absolute URIs or absolute paths [3] in the
link element's href attribute, so clients are required to handle either form.
The
link elements also contain a set of search URIs for certain collections. These URIs use URI templates [4] to integrate search queries. The purpose of the URI template is to accept a search expression using the natural HTTP pattern of a query parameter. The client does not require prior knowledge of the URI structure. Thus clients should treat these templates as being opaque and access them with a URI template library.
Each search query URI template is identified with a relation type using the convention
"collection/search".
| Relationship | Description |
|---|---|
datacenters/search | Query data centers. |
clusters/search | Query host clusters. |
storagedomains/search | Query storage domains. |
hosts/search | Query hosts. |
vms/search | Query virtual machines. |
disks/search | Query disks. |
templates/search | Query templates. |
vmpools/search | Query virtual machine pools. |
events/search | Query events. |
users/search | Query users. |
4.3. Special Object Elements
Special object elements define relationships to special fixed resources within the virtualization environment.
| Relationship | Description |
|---|---|
templates/blank | The default blank virtual machine template for your virtualization environment. This template exists in every cluster as opposed to a standard template, which only exists in a single cluster. |
tags/root | The root tag that acts as a base for tag hierarchy in your virtualization environment. |
4.4. Summary Element
The summary element shows a high level summary of the system's statistics.
| Element | Description |
|---|---|
vms | Total number of vms and total number of active vms. |
hosts | Total number of hosts and total number of active hosts. |
users | Total number of users and total number of active users. |
storage_domains | Total number of storage domains and total number of active storage domains. |
4.5. RESTful Service Description Language (RSDL)
RESTful Service Description Language (RSDL) provides a description of the structure and elements in the REST API in one whole XML specification. Invoke the RSDL using the following request.
GET /ovirt-engine/api?rsdl HTTP/1.1 Accept: application/xml
This produces an XML document in the following format:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<rsdl href="/ovirt-engine/api?rsdl" rel="rsdl">
<description>...</description>
<version major="4" minor="0" build="0" revision="0"/>

4.6. Red Hat Virtualization Windows Guest VSS Support
The Red Hat Virtualization Backup and Restore API provides integration with Microsoft Windows Volume Shadow Copy Service (VSS) using qemu-ga. The VSS provider registration is made in the guest level as part of the Guest Tools deployment.
qemu-ga provides VSS support and live snapshots attempt to quiesce whenever possible.
4.7. QEMU Guest Agent Overview
In Red Hat Enterprise Linux 6.4, the QEMU Guest Agent (QEMU GA) provided protection against the corruption of Linux guest virtual machines. Before issuing a snapshot request or creating a backup copy of the disk, the management stack (libvirt) sent a
guest-fsfreeze-freeze QMP command to the QEMU GA via the virtio-serial port. This command caused the guest agent to freeze all of the guest virtual machine's filesystems, via the FIFREEZE ioctl() kernel function. This ioctl() function is implemented by the Linux kernel in the guest virtual machine. The function flushes the filesystem cache in the guest virtual machine's kernel, brings the filesystem into a consistent state, and denies all userspace threads write access to the filesystem.
Only after the QEMU GA reported success, libvirt would proceed with the snapshot. At its completion, libvirt sends the
guest-fsfreeze-thaw QMP command to the QEMU GA over the virtio-serial port. This command tells the QEMU GA to issue a FITHAW ioctl(), which unblocks the userspace threads that were previously denied write access, and resumes normal processing. This process did not ensure that application-level data was in a consistent state when the virtual disk snapshot was taken. This was evident in cases where the fsck utility found no problems on filesystems restored from snapshots, and yet applications were not able to resume processing from the point where the snapshot was taken and userspace processes may not have written their internal buffers to files on the disk.
Red Hat Enterprise Linux 6.5 ensures that both file and application-level synchronization (flushing) are done. Guest system administrators can write and install application-specific freezing and thawing hook scripts. Before freezing the filesystems, the QEMU GA invokes the main hook script (included in the QEMU GA package). The main hook script in turn calls individual application-specific scripts, prepared by the guest system administrators, that temporarily deactivate all guest virtual machine applications. All of these actions occur when the mode is changed to "freeze".
Just before filesystems are frozen, the guest system administrator's scripts cause the databases and other file system applications to flush their working buffers to the virtual disk and to stop accepting further client connections. The applications then bring their data files into a consistent state where resumption of processing, with the reactivated (or a freshly started) instance of the application (after restoring the virtual disk from backup) is possible. When all scripts are done making their respective applications inactive, and the main hook script returns, QEMU GA proceeds to freeze filesystems, and the management stack takes the snapshot. Once all this is done, and it is confirmed that the snapshot is taken, the file system will resume to serve write requests. This process is called thawing.
Thawing is freezing in reverse order. Instructed by libvirt, QEMU GA thaws the guest virtual machine's filesystems. It then invokes individual hook scripts (via the main hook script) to resume or restart applications that had been inactivated during the freeze process.
4.8. VSS Transaction Flow
In processing a backup, the requester and the writers coordinate to do several things: to provide a stable system image from which to back up data (the shadow copied volume), to group files together on the basis of their usage, and to store information on the saved data. This must all be done with minimal interruption of the writer's normal work flow.
A requester (in our case the Backup Vendor) queries writers for their metadata, processes this data, notifies the writers prior to the beginning of the shadow copy and of the backup operations, and then notifies the writers again after the shadow copy and backup operations end.
Here is how the QEMU VSS provider is registered in Windows OS after the Guest Tools installation:
C:\Users\Administrator>vssadmin list providers
vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool
(C) Copyright 2001-2005 Microsoft Corp.
Provider name: 'QEMU Guest Agent VSS Provider'
Provider type: Software
Provider Id: {3629d4ed-ee09-4e0e-9a5c-6d8ba2872aef}
Version: 0.12.1

The RFC describing Uniform Resource Locator Generic Syntax provides a Collected ABNF for URI that explains the difference between these forms.

The Internet-Draft describing the format of a URI Template is available at http://tools.ietf.org/html/draft-gregorio-uritemplate-03.
Chapter 5. Compatibility Level Versions
Each host connected to Red Hat Virtualization Manager contains a version of VDSM. VDSM is the agent within the virtualization infrastructure that runs on a hypervisor or host and provides local management for virtual machines, networks and storage. Red Hat Virtualization Manager controls hypervisors and hosts using current or older versions of VDSM.
The Manager migrates virtual machines from host to host within a cluster. This means the Manager excludes certain features from a current version of VDSM until all hosts within a cluster have the same VDSM version, or more recent, installed.
The API represents this concept as a
compatibility level for each host, corresponding to the version of VDSM installed. A version element contains major and minor attributes, which describe the compatibility level.
When an administrator upgrades all hosts within a cluster to a certain level, the
version level appears under a supported_versions element. This indicates the cluster's version is now updatable to that level. Once the administrator updates all clusters within a data center to a given level, the data center is updatable to that level.
5.1. Upgrading Compatibility Levels
Example 5.1. Upgrading compatibility levels
The API reports the following compatibility levels for Red Hat Enterprise Virtualization Manager 3.4 instance:
<host ...>
...
<version major="4" minor="14" build="11" revision="0" full_version="vdsm-4.14.11-5.el6ev"/>
...
</host>
<cluster ...>
...
<version major="3" minor="4"/>
...
</cluster>
<data_center ...>
...
<version major="3" minor="4"/>
</supported_versions>
...
</data_center>
All hosts within a cluster are updated to VDSM
3.5 and the API reports:
<host ...>
...
<version major="4" minor="16" build="7" revision="4" full_version="vdsm-4.16.7.4-1.el6ev"/>
...
</host>
<cluster ...>
...
<version major="3" minor="4"/>
<supported_versions>
<version major="3" minor="5"/>
</supported_versions>
...
</cluster>
<data_center ...>
...
<version major="3" minor="4"/>
<supported_versions/>
...
</data_center>
The cluster is now updatable to
3.5. When the cluster is updated, the API reports:
<cluster ...>
...
<version major="3" minor="5"/>
<supported_versions/>
...
</cluster>
<data_center ...>
...
<version major="3" minor="4"/>
<supported_versions>
<version major="3" minor="5"/>
</supported_versions>
...
</data_center>
The API user updates the data center to
3.5. Once upgraded, the API exposes features available in Red Hat Enterprise Virtualization 3.5 for this data center.

7.3.1. Collections
A collection is a set of resources of the same type. The API provides both top-level collections and sub-collections. An example of a top-level collection is the
hosts collection which contains all virtualization hosts in the environment. An example of a sub-collection is the host.nics collection which contains resources for all network interface cards attached to a host resource.
7.3.2. Listing All Resources in a Collection
Obtain a listing of resources in a collection with a
GET request on the collection URI obtained from the entry point.
Include an
Accept HTTP header to define the MIME type for the response format.
GET /ovirt-engine/api/[collection] HTTP/1.1 Accept: [MIME type]
7.3.3. Listing Extended Resource Sub-Collections
The API extends collection representations to include sub-collections when the
Accept header includes the detail parameter.
GET /ovirt-engine/api/collection HTTP/1.1 Accept: application/xml; detail=subcollection
This includes multiple sub-collection requests using either separated
detail parameters:
GET /ovirt-engine/api/collection HTTP/1.1 Accept: application/xml; detail=subcollection1; detail=subcollection2
Or one
detail parameter that separates the sub-collection with the + operator:
GET /ovirt-engine/api/collection HTTP/1.1 Accept: application/xml; detail=subcollection1+subcollection2+subcollection3
The API supports extended sub-collections for the following main collections.
| Collection | Extended Sub-Collection Support |
|---|---|
hosts | statistics |
vms | statistics, nics, disks |
Example 7.1. A request for extended statistics, NICs and disks sub-collections in the vms collection
GET /ovirt-engine/api/vms HTTP/1.1 Accept: application/xml; detail=statistics+nics+disks
7.3.4. Searching Collections with Queries
A
GET request on a "collection/search" link results in a search query of that collection. The API only returns resources within the collection that satisfy the search query constraints.
GET /ovirt-engine/api/collection?search={query} HTTP/1.1
Accept: application/xml
HTTP/1.1 200 OK
Content-Type: application/xml
<collection>
<resource id="resource_id" href="/ovirt-engine/api/collection/resource_id">
...
</resource>
...
</collection>
7.3.5. Maximum Results Parameter
Use the
max URL parameter to limit the list of results. An API search query without specifying the max parameter will return all values. Specifying the max parameter is recommended to prevent API search queries from slowing UI performance.
GET /ovirt-engine/api/collection;max=1 HTTP/1.1
Accept: application/xml
HTTP/1.1 200 OK
Content-Type: application/xml
<collection>
<resource id="resource_id" href="/ovirt-engine/api/collection/resource_id">
<name>Resource-Name</name>
<description>A description of the resource</description>
...
</resource>
</collection>
7.3.6. Case Sensitivity
All search queries are case sensitive by default. The URL syntax provides a Boolean option to toggle case sensitivity.
Example 7.2. Case insensitive search query
GET /ovirt-engine/api/collection;case-sensitive=false?search={query} HTTP/1.1
Accept: application/xml
7.3.7. Query Syntax
The API uses the URI templates to perform a search
query with a GET request:
GET /ovirt-engine/api/collection?search={query} HTTP/1.1
Accept: application/xml
The
query template value refers to the search query the API directs to the collection. This query uses the same format as Red Hat Virtualization Query Language:
(criteria) [sortby (element) asc|desc]
The
sortby clause is optional and only needed when ordering results.
| Collection | Criteria | Result |
|---|---|---|
hosts | vms.status=up | Displays a list of all hosts running virtual machines that are up. |
vms | domain=qa.company.com | Displays a list of all virtual machines running on the specified domain. |
vms | users.name=mary | Displays a list of all virtual machines belonging to users with the user name mary. |
events | severity>normal sortby time | Displays the list of all events with severity higher than normal and sorted by the time element values. |
events | severity>normal sortby time desc | Displays the list of all events with severity higher than normal and sorted by the time element values in descending order. |
The API requires the
query template to be URL-encoded to translate reserved characters, such as operators and spaces.
Example 7.3. URL-encoded search query
GET /ovirt-engine/api/vms?search=name%3Dvm1 HTTP/1.1 Accept: application/xml
7.3.8. Wildcards
Search queries substitute part of a value with an asterisk as a wildcard.
Example 7.4. Wildcard search query for name=vm*
GET /ovirt-engine/api/vms?search=name%3Dvm* HTTP/1.1 Accept: application/xml
This query would result in all virtual machines with names beginning with
vm, such as vm1, vm2, vma or vm-webserver.
Example 7.5. Wildcard search query for name=v*1
GET /ovirt-engine/api/vms?search=name%3Dv*1 HTTP/1.1 Accept: application/xml
This query would result in all virtual machines with names beginning with
v and ending with 1, such as vm1, vr1 or virtualmachine1.
7.3.9. Pagination
Some Red Hat Virtualization environments contain large collections of resources. However, the API only displays a default number of resources for one search query to a collection. To display more than the default, the API separates collections into pages via a search query containing the
page command.
Example 7.6. Paginating resources
This example paginates resources in a collection. The URL-encoded request is:
GET /ovirt-engine/api/collection?search=page%201 HTTP/1.1 Accept: application/xml
Increase the
page value to view the next page of results:
GET /ovirt-engine/api/collection?search=page%202 HTTP/1.1 Accept: application/xml
Use the
page command in conjunction with other commands in a search query. For example:
GET /ovirt-engine/api/collection?search=sortby%20element%20asc%20page%202 HTTP/1.1 Accept: application/xml
This query displays the second page in a collection listing ordered by a chosen element.
Important
The REST APIs are stateless; it is not possible to retain a state between different requests since all requests are independent from each other. As a result, if a status change occurs between your requests, then the page results may be inconsistent.
For example, if you request a specific page from a list of VMs, and a status change occurs before you can request the next page, then your results may be missing entries or contain duplicated entries.
7.3.10. Creating a Resource in a Collection
Create a new resource with a
POST request to the collection URI containing a representation of the new resource.
A
POST request requires a Content-Type header. This informs the API of the representation MIME type in the body content as part of the request.
Include an
Accept HTTP header to define the MIME type for the response format.
Each resource type has its own specific required properties. The client supplies these properties when creating a new resource. Refer to the individual resource type documentation for more details.
If a required property is absent, the creation fails with a representation indicating the missing elements.
POST /ovirt-engine/api/[collection] HTTP/1.1 Accept: [MIME type] Content-Type: [MIME type] [body]
7.3.11. Asynchronous Requests
The API performs asynchronous
POST requests unless the user overrides them with an Expect: 201-created header.
For example, certain resources, such as Virtual Machines, Disks, Snapshots and Templates, are created asynchronously. A request to create an asynchronous resource results in a
202 Accepted status. The initial document structure for a 202 Accepted resource also contains a creation_status element and link for creation status updates. For example:
POST /ovirt-engine/api/collection HTTP/1.1
Accept: application/xml
Content-Type: application/xml
<resource>
<name>Resource-Name</name>
</resource>
HTTP/1.1 202 Accepted
Content-Type: application/xml
<resource id="resource_id" href="/ovirt-engine/api/collection/resource_id">
<name>Resource-Name</name>
<creation_status>
<state>pending</state>
</creation status>
<link rel="creation_status"
href="/ovirt-engine/api/collection/resource_id/creation_status/creation_status_id"/>
...
</resource>
A
GET request to the creation_status link provides a creation status update:
GET /ovirt-engine/api/collection/resource_id/creation_status/creation_status_id HTTP/1.1
Accept: application/xml
HTTP/1.1 200 OK
Content-Type: application/xml
<creation id="creation_status_id"
href="/ovirt-engine/api/collection/resource_id/creation_status/creation_status_id">
<status>
<state>complete</state>
</status>
</creation>
Overriding the asynchronous resource creation requires an
Expect: 201-created header:
POST /ovirt-engine/api/collection HTTP/1.1
Accept: application/xml
Content-Type: application/xml
Expect: 201-created
<resource>
<name>Resource-Name</name>
</resource>
7.4. Resources
7.4.1. Resources
Resources are data sources in a RESTful web service. Each resource type contains a set of common parameters that the REST API abstracts to form a resource representation, usually in XML or JSON. Users can view a resource representation, then edit the parameters and send the representation back to the resource's URL within the API, which modifies the resource. Users can also delete individual resources through REST.
A RESTful web service also groups resources into collections. Users can view a representation of all resources in a collection. Users also send resource representations to a specific collection to create a new resource within that particular collection.
7.4.2. Retrieving a Resource
Obtain the state of a resource with a
GET request on a URI obtained from a collection listing.
Include an
Accept HTTP header to define the MIME type for the response format.
GET /ovirt-engine/api/[collection]/[resource_id] HTTP/1.1 Accept: [MIME type]
You can obtain additional information from some resources using the
All-Content: true header. The RESTful Service Description Language describes which links support this header.
GET /ovirt-engine/api/[collection]/[resource_id] HTTP/1.1 Accept: [MIME type] All-Content: true
7.4.3. Updating a Resource
Modify resource properties with a
PUT request containing an updated description from a previous GET request for the resource URI. Details on modifiable properties are found in the individual resource type documentation.
A
PUT request requires a Content-Type header. This informs the API of the representation MIME type in the body content as part of the request.
Include an
Accept HTTP header to define the MIME type for the response format.
PUT /ovirt-engine/api/collection/resource_id HTTP/1.1 Accept: [MIME type] Content-Type: [MIME type] [body]
This does not include immutable resource properties that an API user has attempted to modify. If an attempt is made to modify a strictly immutable resource property, the API reports a conflict with an error message representation in the response body.
Properties omitted from the representation are ignored and not changed.
7.4.4. Deleting a Resource
Delete a resource with a
DELETE request sent to its URI.
Include an
Accept HTTP header to define the MIME type for the response format.
DELETE /ovirt-engine/api/[collection]/[resource_id] HTTP/1.1 Accept: [MIME type]
Some cases require optional body content in the
DELETE request to specify additional properties. A DELETE request with optional body content requires a Content-Type header to inform the API of the representation MIME type in the body content. If a DELETE request contains no body content, omit the Content-Type header.
7.4.5. Sub-Collection Relationships
A sub-collection relationship defines a hierarchical link between a resource and a sub-collection. The sub-collection exists or has some meaning in the context of a parent resource. For example, a virtual machine contains network interfaces, which means the API maps the relationship between the virtual machine resource and the network interfaces sub-collection.
Sub-collections are used to model the following relationships types:
- Where one parent resource can contain several child resources and vice versa. For example, a virtual machine can contain several disks and some disks are shared among multiple virtual machines.
- Where mapped resources are dependent on a parent resource. Without the parent resource, the dependent resource cannot exist. For example, the link between a virtual machine and snapshots.
- Where mapped resources exist independently from parent resources but data is still associated with the relationship. For example, the link between a cluster and a network.
The API defines a relationship between a resource and a sub-collection using the
link rel= attribute:
GET /ovirt-engine/api/collection/resource_id HTTP/1.1
Accept: application/xml
HTTP/1.1 200 OK
Content-Type: application/xml
<resource id="resource_id" href="/ovirt-engine/api/collection/resource_id">
...
<link rel="subcollection"
href="/ovirt-engine/api/collection/resource_id/subcollection"/>
...
</resource>
The API user now queries the sub-collection.
GET /ovirt-engine/api/collection/resource_id/subcollection HTTP/1.1
Accept: application/xml
HTTP/1.1 200 OK
Content-Type: application/xml
<subcollection>
<subresource id="subresource_id"
href="/ovirt-engine/api/collection/resource_id/subcollection/subresource_id">
...
</subresource>
...
</subcollection>
7.4.6. XML Element Relationships
XML element links act as an alternative to sub-collections to express relationships between resources. XML element links are simply elements with a "href" attribute that points to the linked element.
XML element links are used to model simple 1:N mappings between resources without a dependency and without data associated with the relationship. For example, the relationship between a host and a cluster.
Examples of such relationships include:
- Backlinks from a resource in a sub-collection to a parent resource; or
- Links between resources with an arbitrary relationship.
Example 7.7. Backlinking from a sub-collection resource to a resource using an XML element
GET /ovirt-engine/api/collection/resource_id/subcollection/subresource_id HTTP/1.1
HTTP/1.1 200 OK
Content-Type: application/xml
<subcollection>
<subresource id="subresource_id"
href="/ovirt-engine/api/collection/resource_id/subcollection/subresource_id">
<resource id="resource_id" href="/ovirt-engine/api/collection/resource_id"/>
...
</subresource>
</subcollection>
7.4.7. Actions
Most resources include a list of action links to provide functions not achieved through the standard HTTP methods.
<resource>
...
<actions>
<link rel="start" href="/ovirt-engine/api/collection/resource_id/start"/>
<link rel="stop" href="/ovirt-engine/api/collection/resource_id/stop"/>
...
</actions>
...
</resource>
The API invokes an action with a
POST request to the supplied URI. The body of the POST requires an action representation encapsulating common and task-specific parameters.
| Element | Description |
|---|---|
async | true if the server responds immediately with 202 Accepted and an action representation contains a href link to be polled for completion. |
grace_period | a grace period in milliseconds, which must expire before the action is initiated. |
Individual actions and their parameters are documented in the individual resource type's documentation. Some parameters are mandatory for specific actions and their absence is indicated with a
fault response.
An action also requires a
Content-Type: application/xml header since the POST request requires an XML representation in the body content.
When the action is initiated asynchronously, the immediate
202 Accepted response provides a link to monitor the status of the task:
POST /ovirt-engine/api/collection/resource_id/action HTTP/1.1
Content-Type: application/xml
Accept: application/xml
<action>
<async>true</async>
</action>
HTTP/1.1 202 Accepted
Content-Type: application/xml
<action id="action_id"
href="/ovirt-engine/api/collection/resource_id/action/action_id">
<async>true</async>
...
</action>
A subsequent
GET on the action URI provides an indication of the status of the asynchronous task.
| Status | Description |
|---|---|
pending | Task has not yet started. |
in_progress | Task is in operation. |
complete | Task completed successfully. |
failed | Task failed. The returned action representation would contain a fault describing the failure. |
Once the task has completed, the action is retained for an indeterminate period. Once this has expired, subsequent
GETs are 301 Moved Permanently redirected back to the target resource.
GET /ovirt-engine/api/collection/resource_id/action/action_id HTTP/1.1
Accept: application/xml
HTTP/1.1 200 OK
Content-Type: application/xml
<action id="action_id"
href="/ovirt-engine/api/collection/resource_id/action/action_id">
<status>
<state>pending</state>
</status>
<link rel="parent" /ovirt-engine/api/collection/resource_id"/>
<link rel="replay" href="/ovirt-engine/api/collection/resource_id/action"/>
</action>
An action representation also includes some links that are identified by the
rel attribute:
| Type | Description |
|---|---|
parent | A link back to the resource of this action. |
replay | A link back to the original action URI. POSTing to this URI causes the action to be re-initiated. |
7.4.8. Permissions
Each resource contains a
permissions sub-collection. Each permission contains a user, an assigned role and the specified resource. For example:
GET /ovirt-engine/api/collection/resource_id/permissions HTTP/1.1
Accept: application/xml
HTTP/1.1 200 OK
Content-Type: application/xml
<permissions>
<permission id="permission-id"
href="/ovirt-engine/api/collection/resource_id/permissions/permission_id">
<role id="role_id" href="/ovirt-engine/api/roles/role_id"/>
<user id="user_id" href="/ovirt-engine/api/users/user_id"/>
<resource id="resource_id" href="/ovirt-engine/api/collection/resource_id"/>
</permission>
...
</permissions>
A resource acquires a new permission when an API user sends a
POST request with a permission representation and a Content-Type: application/xml header to the resource's permissions sub-collection. Each new permission requires a role and a user:
POST /ovirt-engine/api/collection/resource_id/permissions HTTP/1.1
Content-Type: application/xml
Accept: application/xml
<permission>
<role id="role_id"/>
<user id="user_id"/>
</permission>
HTTP/1.1 201 Created
Content-Type: application/xml
<permission id="permission_id"
href="/ovirt-engine/api/resources/resource_id/permissions/permission_id">
<role id="role_id" href="/ovirt-engine/api/roles/role_id"/>
<user id="user_id" href="/ovirt-engine/api/users/user_id"/>
<resource id="resource_id" href="/ovirt-engine/api/collection/resource_id"/>
</permission>
7.4.9. Handling Errors
Some errors require further explanation beyond a standard HTTP status code. For example, the API reports an unsuccessful resource state update or action with a
fault representation in the response entity body. The fault contains a reason and detail strings. Clients must accommodate failed requests via extracting the fault or the expected resource representation depending on the response status code. Such cases are clearly indicated in the individual resource documentation.
PUT /ovirt-engine/api/collection/resource_id HTTP/1.1
Accept: application/xml
Content-Type: application/xml
<resource>
<id>id-update-test</id>
</resource>
HTTP/1.1 409 Conflict
Content-Type: application/xml
<fault>
<reason>Broken immutability constraint</reason>
<detail>Attempt to set immutable field: id</detail>
</fault>
Chapter 8. The Backup and Restore API
The backup and restore API is a collection of functions that allows you to perform full or file-level backup and restoration of virtual machines. The API combines several components of Red Hat Virtualization, such as live snapshots and the REST API, to create and work with temporary volumes that can be attached to a virtual machine containing backup software provided by an independent software provider.
For supported third-party backup vendors, consult the Red Hat Virtualization Ecosystem at Red Hat Marketplace.
8.1. Backing Up a Virtual Machine
Use the backup and restore API to back up a virtual machine. This procedure assumes you have two virtual machines: the virtual machine to back up, and a virtual machine on which the software for managing the backup is installed.
Procedure 8.1. Backing Up a Virtual Machine
- Using the REST API, create a snapshot of the virtual machine to back up:
POST /ovirt-engine/api/vms/11111111-1111-1111-1111-111111111111/snapshots/ HTTP/1.1 Accept: application/xml Content-type: application/xml <snapshot> <description>BACKUP</description> </snapshot>Note
When you take a snapshot of a virtual machine, a copy of the configuration data of the virtual machine as at the time the snapshot was taken is stored in thedataattribute of theconfigurationattribute ininitializationunder the snapshot.Important
You cannot take snapshots of disks that are marked as shareable or that are based on direct LUN disks. - Retrieve the configuration data of the virtual machine from the
dataattribute under the snapshot:GET /ovirt-engine/api/vms/11111111-1111-1111-1111-111111111111/snapshots/11111111-1111-1111-1111-111111111111 HTTP/1.1 Accept: application/xml Content-type: application/xml
- Identify the disk ID and snapshot ID of the snapshot:
GET /ovirt-engine/api/vms/11111111-1111-1111-1111-111111111111/snapshots/11111111-1111-1111-1111-111111111111/disks HTTP/1.1 Accept: application/xml Content-type: application/xml
- Attach the snapshot to the backup virtual machine and activate the disk:
POST /ovirt-engine/api/vms/22222222-2222-2222-2222-222222222222/disks/ HTTP/1.1 Accept: application/xml Content-type: application/xml <disk id="11111111-1111-1111-1111-111111111111"> <snapshot id="11111111-1111-1111-1111-111111111111"/> <active>true</active> </disk> - Use the backup software on the backup virtual machine to back up the data on the snapshot disk.
- Detach the snapshot disk from the backup virtual machine:
DELETE /ovirt-engine/api/vms/22222222-2222-2222-2222-222222222222/disks/11111111-1111-1111-1111-111111111111 HTTP/1.1 Accept: application/xml Content-type: application/xml <action> <detach>true</detach> </action> - Optionally, delete the snapshot:
DELETE /ovirt-engine/api/vms/11111111-1111-1111-1111-111111111111/snapshots/11111111-1111-1111-1111-111111111111 HTTP/1.1 Accept: application/xml Content-type: application/xml
You have backed up the state of a virtual machine at a fixed point in time using backup software installed on a separate virtual machine.
8.2. Restoring a Virtual Machine
Restore a virtual machine that has been backed up using the backup and restore API. This procedure assumes you have a backup virtual machine on which the software used to manage the previous backup is installed.
Procedure 8.2. Restoring a Virtual Machine
- Attach the disk to the backup virtual machine:
POST /ovirt-engine/api/vms/22222222-2222-2222-2222-222222222222/disks/ HTTP/1.1 Accept: application/xml Content-type: application/xml <disk id="11111111-1111-1111-1111-111111111111"> </disk>
- Use the backup software to restore the backup to the disk.
- Detach the disk from the backup virtual machine:
DELETE /ovirt-engine/api/vms/22222222-2222-2222-2222-222222222222/disks/11111111-1111-1111-1111-111111111111 HTTP/1.1 Accept: application/xml Content-type: application/xml <action> <detach>true</detach> </action> - Create a new virtual machine using the configuration data of the virtual machine being restored:
POST /ovirt-engine/api/vms/ HTTP/1.1 Accept: application/xml Content-type: application/xml <vm> <cluster> <name>cluster_name</name> </cluster> <name>NAME</name> ... </vm> - Attach the disk to the new virtual machine:
POST /ovirt-engine/api/vms/33333333-3333-3333-3333-333333333333/disks/ HTTP/1.1 Accept: application/xml Content-type: application/xml <disk id="11111111-1111-1111-1111-111111111111"> </disk>
You have restored a virtual machine using a backup that was created using the backup and restore API.
Chapter 9. Data Centers
9.1. Data Center Elements
The
datacenters collection provides information about the data centers in a Red Hat Virtualization environment. An API user accesses this information through the rel="datacenters" link obtained from the entry point URI.
The following table shows specific elements contained in a data center resource representation.
| Element | Type | Description | Properties |
|---|---|---|---|
name | string | A plain text, human-readable name for the data center. The name is unique across all data center resources. |
|
description | string | A plain text, human-readable description of the data center | |
link rel="storagedomains" | relationship | A link to the sub-collection for storage domains attached to this data center. | |
link rel="clusters" | relationship | A link to the sub-collection for clusters attached to this data center. | |
link rel="networks" | relationship | A link to the sub-collection for networks available to this data center. | |
link rel="permissions" | relationship | A link to the sub-collection for data center permissions. | |
link rel="quotas" | relationship | A link to the sub-collection for quotas associated with this data center. | |
local | Boolean: true or false | Specifies whether the data center is a local data center, such as created in all-in-one instances. |
|
storage_format | enumerated | Describes the storage format version for the data center. A list of enumerated values are available in capabilities. | |
version major= minor= | complex | The compatibility level of the data center. | |
supported_versions | complex | A list of possible version levels for the data center, including version major= minor=. |
|
mac_pool | string | The MAC address pool associated with the data center. If no MAC address pool is specified the default MAC address pool is used. | |
status | see below | The data center status. |
|
The
status contains one of the following enumerated values: uninitialized, up, maintenance, not_operational, problematic and contend. These states are listed in data_center_states under capabilities.
9.2. XML Representation of a Data Center

DELETE request.
Example 9.5. Removing a data center
DELETE /ovirt-engine/api/datacenters/00000000-0000-0000-0000-000000000000 HTTP/1.1 HTTP/1.1 204 No Content
9.5. Sub-Collections
9.5.1. Storage Domains Sub-Collection
9.5.1.1. Storage Domains Sub-Collection
Each data center contains a sub-collection for attached storages domain. An API user interacts with this sub-collection using the standard REST methods.
An attached storage domain has a similar representation to a top-level storage domain, with the exception that it has a data center specific
status and set of actions. States for the status element are listed in storage_domain_states under capabilities.
Important
The API as documented in this section is experimental and subject to change. It is not covered by the backwards compatibility statement.
9.5.1.2. Attaching and Detaching a Storage Domain
A data center is only ready for use when at least one storage domain is attached, which an API user
POSTs to the data center's storage domains sub-collection.
When attaching a storage domain, its
id or name must be supplied. An example of attaching a storage domain to a data center:
Example 9.6. Attach a storage domain to a data center
POST /ovirt-engine/api/datacenters/d70d5e2d-b8ad-494a-a4d2-c7a5631073c4/storagedomains HTTP/1.1

9.5.2. Network Sub-Collection
9.5.2.1. Networks Sub-Collection
Networks associated with a data center are represented with the
networks sub-collection. The representation of a data center's network sub-collection contains the following elements:
| Element | Type | Description |
|---|---|---|
name | string | A plain text, human readable name for the network. |
description | string | A plain text, human readable description of the network. |
rel="permissions" | relationship | A link to the permissions sub-collection for the network. |
rel="vnicprofiles" | relationship | A link to the vnicprofiles sub-collection for the network. |
rel="labels" | relationship | A link to the labels sub-collection for the network. |
data_center id= | relationship | A reference to the data center of which the network is a member. |
stp | Boolean: true or false | Specifies whether spanning tree protocol is enabled for the network. |
mtu | integer | Specifies the maximum transmission unit for the network. |
usages | complex | Defines a set of usage elements for the network. Users can define networks as vm and display networks at this level. |
In the REST API, you can manipulate the
networks sub-collection with the standard REST methods. For example, the POST method can be used to update a network id or name
Example 9.10. Associating a network resource with a data center

<data_center href= "/ovirt-engine/api/datacenters/56087282-d7a6-11e1-af44-001a4a400e0c"
id="56087282-d7a6-11e1-af44-001a4a400e0c"/>
</quota>
Creation of a new quota requires the
name and description elements.
Example 9.14. Creating a quota
POST /ovirt-engine/api/datacenters/56087282-d7a6-11e1-af44-001a4a400e0c/quotas HTTP/1.1
Accept: application/xml
Content-type: application/xml
<quota>
<name>VMQuota</name>
<description>My new quota for virtual machines</description>
</quota>
Removal of a quota requires a
DELETE request.
Example 9.15. Removing a quota
DELETE /ovirt-engine/api/datacenters/01a45ff0-915a-11e0-8b87-5254004ac988/quotas/e13ff85a-b2ba-4f7b-8010-e0d057c03dfe HTTP/1.1 HTTP/1.1 204 No Content
9.6. Actions
9.6.1. Force Remove Data Center Action
An API user forces the removal of a data center when encountering unresolvable problems with storage domains, such as the loss of connection to a master storage domain or a lack of available hosts when deleting storage domains. The API includes a
force action to help with these situations.
This action removes database entries associated with a chosen data center before the API removes the data center from the Red Hat Virtualization environment. This means the API removes the data center regardless of associated storage domains.
This action requires a
DELETE method. The request body contains an action representation with the force parameter set to true. The request also requires an additional Content-type: application/xml header to process the XML representation in the body.
Example 9.16. Force remove action on a data center
DELETE /ovirt-engine/api/datacenters/00000000-0000-0000-0000-000000000000 HTTP/1.1 Accept: application/xml Content-type: application/xml <action> <force>true</force> </action>
This action:
- Deletes all database information for
datastorage domains associated the data center; - Deletes all database information for resources, such as virtual machines and templates, on
datastorage domains associated the data center; - Detaches
isoandexportstorage domains from the data center; and - Deletes the database information for the data center.
This action overrides the requirement for a data center to be empty before deletion.
Important
This action only removes the database entries for resources associated with the data center. The
data storage domains associated with the data center require manual format before reuse. Metadata for iso and export domains require manual cleaning prior to use on another data center.
Chapter 10. Clusters
10.1. Cluster Elements
The
clusters collection provides information about clusters in a Red Hat Virtualization environment. An API user accesses this information through the rel="clusters" link obtained from the entry point URI.
The following table shows specific elements contained in a cluster resource representation.
| Element | Type | Description | Properties |
|---|---|---|---|
name | string | A user-supplied, human-readable name for the cluster. The name is unique across all cluster resources. |
|
description | string | A free-form, user-supplied, human-readable description of the cluster. | |

link rel="permissions" | relationship | A link to the sub-collection for cluster permissions. | |
link rel="glustervolumes" | relationship | A link to the sub-collection for Red Hat Gluster Storage volumes associated with this cluster. | |
link rel="glusterhooks" | relationship | A link to the sub-collection for Red Hat Gluster Storage volume hooks associated with this cluster. | |
link rel="affinitygroups" | relationship | A link to the sub-collection for virtual machine affinity groups associated with this cluster. | |
cpu id= | complex | A server CPU reference that defines the CPU type all hosts must support in the cluster. |
|
data_center id= | GUID | A reference to the data center membership of this cluster. |
|
memory_policy | complex | Defines the cluster's policy on host memory utilization. |
|
scheduling_policy | complex | Defines the load-balancing or power-saving modes for hosts in the cluster. |
|
version major= minor= | complex | The compatibility level of the cluster. |
|
supported_versions | complex | A list of possible version levels for the cluster. |
|
error_handling | complex/enumerated | Defines virtual machine handling when a host within a cluster becomes non-operational. Requires a single on_error element containing an enumerated type property listed in capabilities. | |
virt_service | Boolean | Defines whether to expose virtualization services for this cluster. | |
gluster_service | Boolean | Defines whether to expose Red Hat Gluster Storage services for this cluster. | |
threads_as_cores | Boolean | Defines whether hosts can run virtual machines with a total number of processor cores greater than the number of cores in the host. | |
tunnel_migration | Boolean | Defines whether virtual machines use a libvirt-to-libvirt tunnel during migration. | |
trusted_service | Boolean | Defines whether an OpenAttestation server is used to verify hosts. | |
ballooning_enabled | Boolean | Defines whether ballooning is enabled for the cluster. | |
ksm | Boolean | Defines whether ksm is enabled for the cluster. |
Note
When a host's free memory drops below 20%, ballooning commands like
mom.Controllers.Balloon - INFO Ballooning guest:half1 from 1096400 to 1991580 are logged to /etc/vdsm/mom.conf. /etc/vdsm/mom.conf is the Memory Overcommit Manager log file. An event will also be added to the event log if a virtual machine does not respect a balloon.
10.2. Memory Policy Elements
The
memory_policy element contains the following elements:
| Element | Type | Description | Properties |
|---|---|---|---|
overcommit percent= | complex | The percentage of host memory allowed in use before no more virtual machines can start on a host. Virtual machines can use more than the available host memory due to memory sharing under KSM. Recommended values include 100 (None), 150 (Server Load) and 200 (Desktop Load). |
|
transparent_hugepages | complex | Define the enabled status of Transparent Hugepages. The status is either true or false. Check capabilities feature set to ensure your version supports transparent hugepages. |
|
10.3. Scheduling Policy Elements
The
scheduling_policy element contains the following elements:
| Element | Type | Description | Properties |
|---|---|---|---|
policy | enumerated | The VM scheduling mode for hosts in the cluster. A list of enumerated types are listed in capabilities. |
|
thresholds low= high= duration= | complex | Defines CPU limits for the host. The high attribute controls the highest CPU usage percentage the host can have before being considered overloaded. The low attribute controls the lowest CPU usage percentage the host can have before being considered underutilized. The duration attribute refers to the number of seconds the host needs to be overloaded before the scheduler starts and moves the load to another host. |

10.7. Sub-Collections
10.7.1. Networks Sub-Collection
10.7.1.1. Networks Sub-Collection
Networks associated with a cluster are represented with the
networks sub-collection. Every host within a cluster connects to these associated networks.
The representation of a cluster's
network sub-collection is the same as a standard network resource except for the following additional elements:
| Element | Type | Description | Properties |
|---|---|---|---|
cluster id= | relationship | A reference to the cluster of which this network is a member. |
|
required | Boolean | Defines required or optional network status. | |
display | Boolean | Defines the display network status. Used for backward compatibility. | |
usages | complex | Defines a set of usage elements for the network. Users can define networks as VM and DISPLAY networks at this level. |
An API user manipulates the
networks sub-collection with the standard REST methods. POSTing a network id or name reference to the networks sub-collection associates the network with the cluster.
Example 10.6. Associating a network resource with a cluster

12.4. Methods
12.4.1. Creating a Storage Domain
Creation of a new storage domain requires the
name, type, host and storage elements. Identify the host element with the id attribute or name element.
You can enable the wipe after delete option by default on the storage domain by specifying
<wipe_after_delete> in the POST request. This option can be edited after the domain is created, but doing so will not change the wipe after delete property of disks that already exist.
Example 12.3. Creating a storage domain
POST /ovirt-engine/api/storagedomains HTTP/1.1
Accept: application/xml
Content-type: application/xml
<storage_domain>
<name>data1</name>
<type>data</type>
<host id="2ab5e1da-b726-4274-bbf7-0a42b16a0fc3"/>
<storage>
<type>nfs</type>
<address>172.31.0.6</address>
<path>/exports/RHEVX/images/0</path>
</storage>
</storage_domain>
The API user attaches the storage domain to a data center after creation.
12.4.2. Updating a Storage Domain
Only the
name and wipe after delete elements are updatable post-creation. Changing the wipe after delete element will not change the wipe after delete property of disks that already exist.
Example 12.4. Updating a storage domain
PUT /ovirt-engine/api/storagedomains HTTP/1.1
Accept: application/xml
Content-type: application/xml
<storage_domain>
<name>data2</name>
...
<wipe_after_delete>true</wipe_after_delete>
...
</storage_domain>
12.4.3. Removing a Storage Domain
Removal of a storage domain requires a
DELETE request.
Example 12.5. Removing a storage domain
DELETE /ovirt-engine/api/storagedomains/fabe0451-701f-4235-8f7e-e20e458819ed HTTP/1.1 HTTP/1.1 204 No Content
12.5. Storage Types
12.5.1. Storage Types
The
storage element contains a type element, which is an enumerated value found under the capabilities collection.
The storage element also contains additional elements specific to each storage
type. The next few sections examine these additional storage type elements.
12.5.2. NFS Storage
The following table contains
nfs specific elements in a storage description.
| Element | Type | Description | Properties |
|---|---|---|---|
address | string | The host name or IP address of the NFS server. |
|
path | string | The path of NFS mountable directory on the server. |
|
12.5.3. PosixFS Storage
The following table contains
posixfs specific elements in a storage description.
| Element | Type | Description | Properties |
|---|---|---|---|
address | string | The host name or IP address of the PosixFS server. |
|
path | string | The path of PosixFS mountable directory on the server. |
|
vfs_type | string | The Linux-supported file system type of the PosixFS share. |
|
mount_options | string | The options for mounting the PosixFS share. |
|
12.5.4. iSCSI and FCP Storage
The following table contains
iscsi and fcp specific elements in a storage description.
| Element | Type | Description | Properties |
|---|---|---|---|
logical_unit id= | complex | The id of the logical unit. A storage domain also accepts multiple iSCSI or FCP logical units. |
|
override_luns | Boolean | Defines whether to replace all logical unit settings with new settings. Set to true to override. |
|
The
logical_unit contains a set of sub-elements.
| Element | Type | Description | Properties |
|---|---|---|---|
address | string | The address of the server containing the storage device. |
|
port | integer | The port number of the server. |
|
target | string | The target IQN for the storage device. |
|
username | string | A CHAP user name for logging into a target. |
|
password | string | A CHAP password for logging into a target. |
|
serial | string | The serial ID for the target. |
|
vendor_id | string | The vendor name for the target. |
|
product_id | string | The product code for the target. |
|
lun_mapping | integer | The Logical Unit Number device mapping for the target. |
|
In the case of iSCSI, if a
logical_unit description also contains details of the iSCSI target with the LUN in question, the target performs an automatic login when the storage domain is created.
12.5.5. LocalFS Storage
The
localfs specific elements in a storage description are:
| Element | Type | Description | Properties |
|---|---|---|---|
path | string | The path of local storage domain on the host. |
|
A
localfs storage domain requires a data center with storage_type set to localfs. This data center only contains a single host cluster, and the host cluster only contains a single host.
12.6. Export Storage Domains
12.6.1. Export Storage Domains
Note
The export storage domain is deprecated. Storage data domains can be unattached from a data center and imported to another data center in the same environment, or in a different environment. Virtual machines, floating virtual disk images, and templates can then be uploaded from the imported storage domain to the attached data center. See the Importing Existing Storage Domains section in the Red Hat Virtualization Administration Guide for information on importing storage domains.
Storage domains with
type set to export contain vms and templates sub-collections, which list the import candidate VMs and templates stored on that particular storage domain.
Example 12.6. Listing the virtual machines sub-collection of an export storage domain
GET /ovirt-engine/api/storagedomains/fabe0451-701f-4235-8f7e-e20e458819ed/vms

12.7. Glance Image Storage Domains
12.7.1. Glance Image Storage Domains
Storage domains with type set to
Image represent instances of an OpenStack image service that has been added to the Red Hat Virtualization environment as an external provider. These Glance image storage domains contain an images sub-collection with virtual machine images that have been exported to or can be imported from that Glance image storage domain.
Example 12.12. Listing the images sub-collection of a Glance image storage domain

12.8. Importing a Block Storage Domain
12.8.1. Importing a Block Storage Domain
An existing block storage domain with
type set to iscsi or fcp can be imported to the engine using the REST API. The ability to import storage domains allows you to recover data in the event of a failure in the engine database, and to migrate data from one data center or environment to another.
This procedure assumes the storage domain is not attached to a data center or host in any environment. To import and attach an existing block storage domain to a data center, the target data center must be initialized.
Procedure 12.1. Importing a block storage domain
- Discover the targets on your iSCSI storage server:
POST /ovirt-engine/api/hosts/052a880a-53e0-4fe3-9ed5-01f939d1df66/iscsidiscover Accept: application/xml Content-Type: application/xml <action> <iscsi> <address>192.0.2.0</address> <port>3260</port> </iscsi> </action> - Get a list of storage domains that are candidates to be imported, using the iSCSI targets discovered in the previous step:
POST /ovirt-engine/api/hosts/052a880a-53e0-4fe3-9ed5-01f939d1df66/unregisteredstoragedomainsdiscover HTTP/1.1 Accept: application/xml Content-type: application/xml <action> <iscsi> <address>192.0.2.0</address> </iscsi> <iscsi_target>iqn.name1.120.01</iscsi_target> <iscsi_target>iqn.name2.120.02</iscsi_target> <iscsi_target>iqn.name3.120.03</iscsi_target> </action>The response shows a list of storage domains not associated with a host, similar to the following:<action> <iscsi> <address>192.0.2.0</address> </iscsi> <storage_domains> <storage_domain id="6ab65b16-0f03-4b93-85a7-5bc3b8d52be0"> <name>scsi4</name> <type>data</type> <external_status> <state>ok</state> </external_status> <master>false</master> <storage> <type>iscsi</type> <volume_group id="OLkKwa-VmEM-abW7-hPiv-BGrw-sQ2E-vTdAy1"/> </storage> <available>0</available> <used>0</used> <committed>0</committed> <storage_format>v3</storage_format> </storage_domain> <status> <state>complete</state> </status> <iscsi_target>iqn.name1.120.01</iscsi_target> <iscsi_target>iqn.name2.120.02</iscsi_target> <iscsi_target>iqn.name3.120.03</iscsi_target> </action> - Import the iSCSI storage domains to the host:
POST /ovirt-engine/api/storagedomains/ HTTP/1.1 Accept: application/xml Content-type: application/xml <storage_domain id="6ab65b16-0f03-4b93-85a7-5bc3b8d52be0"> <import>true</import> <host id="052a880a-53e0-4fe3-9ed5-01f939d1df66" /> <type>data</type> <storage> <type>iscsi</type> </storage> </storage_domain>
You have now imported the block storage domain to your host.
You may now wish to attach the storage domain to the host, and find any unregistered disks. Attach the storage domain and associated disks with the following steps:
Procedure 12.2. Attaching a block storage domain
- Attach the storage domain to your data center:
POST /ovirt-engine/api/datacenters/01a45ff0-915a-45e0-8d56-5253234ac988/storagedomains Accept: application/xml Content-Type: application/xml <storage_domain> <name>scsi4</name> </storage_domain> - Find the unregistered disks on the storage domain:
GET /ovirt-engine/api/storagedomains/6ab65b16-0f03-4b93-85a7-5bc3b8d52be0/disks;unregistered Accept: application/xml Content-Type: application/xml
This will return information about any unregistered disks on the storage domain, with a response similar to:<disk href= "/ovirt-engine/api/storagedomains/6ab65b16-0f03-4b93-85a7-5bc3b8d52be0/disks/b662f6da-3e97-4bb6-8a50-bda9980a6e83" id="b662f6da-3e97-4bb6-8a50-bda9980a6e83"> <actions> <link href= "/ovirt-engine/api/storagedomains/6ab65b16-0f03-4b93-85a7-5bc3b8d52be0/disks/b662f6da-3e97-4bb6-8a50-bda9980a6e83/export" rel="export"/> </actions> <name>disk1</name> <description/> <link href= "/ovirt-engine/api/storagedomains/6ab65b16-0f03-4b93-85a7-5bc3b8d52be0/disks/b662f6da-3e97-4bb6-8a50-bda9980a6e83/permissions" rel="permissions"/> <link href= "/ovirt-engine/api/storagedomains/6ab65b16-0f03-4b93-85a7-5bc3b8d52be0/disks/b662f6da-3e97-4bb6-8a50-bda9980a6e83/statistics" rel="statistics"/> <alias>disk1</alias> <image_id>930d653e-2a11-45ce-8042-9935584a3f87</image_id> <storage_domain href= "/ovirt-engine/api/storagedomains/6ab65b16-0f03-4b93-85a7-5bc3b8d52be0" id="8ac10ec5-7cc9-4b1c-9c97-f121a9e4679a"/> <storage_domains> <storage_domain id="6ab65b16-0f03-4b93-85a7-5bc3b8d52be0"/> </storage_domains> <size>10737418240</size> <provisioned_size>10737418240</provisioned_size> <actual_size>10737418240</actual_size> <status> <state>ok</state> </status> <interface>ide</interface> <format>raw</format> <sparse>false</sparse> <bootable>false</bootable> <shareable>false</shareable> <wipe_after_delete>false</wipe_after_delete> <propagate_errors>false</propagate_errors> <storage_type>image</storage_type> </disk> - Attach the disk to the storage domain:
POST /ovirt-engine/api/storagedomains/6ab65b16-0f03-4b93-85a7-5bc3b8d52be0/disks;unregistered Accept: application/xml Content-Type: application/xml <disk id='b662f6da-3e97-4bb6-8a50-bda9980a6e83'></disk>
The disk is now attached to the imported block storage domain.
12.9. Sub-Collections
12.9.1. Files Sub-Collection
The
files sub-collection under each storage domain provides a way for clients to list available files. This sub-collection is specifically targeted to ISO storage domains, which contain ISO images and virtual floppy disks (VFDs) that an administrator uploads through Red Hat Virtualization Manager.
The addition of a CD-ROM device to a VM requires an ISO image from the
files sub-collection of an ISO storage domain.
Example 12.15. Listing the files sub-collection of an ISO storage domain

12.10. Actions
12.10.1. Importing an Existing Storage Domain
Note
The export storage domain is deprecated. Storage data domains can be unattached from a data center and imported to another data center in the same environment, or in a different environment. Virtual machines, floating virtual disk images, and templates can then be uploaded from the imported storage domain to the attached data center. See the Importing Existing Storage Domains section in the Red Hat Virtualization Administration Guide for information on importing storage domains.
The API provides a user with the ability to remove an ISO or Export storage domain from one Red Hat Virtualization Manager instance without re-formatting the underlying storage and import it into another instance. Importing is achieved similarly to adding a new storage domain, except the
name is not specified.
Example 12.16. Importing an existing export storage domain
POST /ovirt-engine/api/storagedomains HTTP/1.1
Accept: application/xml
Content-Type: application/xml
<storage_domain>
<type>export</type>
<storage>
<type>nfs</type>
<address>172.31.0.6</address>
<path>/exports/RHEVX/export-domain</path>
</storage>
<host id="2ab5e1da-b726-4274-bbf7-0a42b16a0fc3"/>
</storage_domain>
HTTP/1.1 201 Created
Content-Type: application/xml
<storage_domain id="fabe0451-701f-4235-8f7e-e20e458819ed"
href="/ovirt-engine/api/storagedomains/fabe0451-701f-4235-8f7e-e20e458819ed">
<name>export1</name>
...
</storage_domain>
12.10.2. Deleting a Storage Domain
A
storage_domain reference is passed in the body of a DELETE request for a storage domain. The storage_domain reference is in the following form:
<storage_domain>
<host id="..."/>
</storage_domain>
OR
<storage_domain>
<host>
<name>...</name>
</host>
</storage_domain>
Format Storage Domain
An API user provides a optional format element to specify whether or not to format the storage domain after deletion.
Example 12.17. Formatting a storage domain after deletion
<storage_domain>
<host id="..."/>
<format>true</format>
</storage_domain>
If no
format element is passed, the storage domain remains unformatted.
Logical Removal of Storage Domain
The API also provides a function for the logical removal of the storage domain. This retains the storage domain's data for import. Use the destroy element to logically remove the storage domain and retain the data.
Example 12.18. Logical removal of a storage domain
<storage_domain>
<host id="..."/>
<destroy>true</destroy>
</storage_domain>
12.10.3. Refreshing the LUN Size
Users can refresh the LUN size after increasing the size of the underlying LUN on the storage server. The
refreshluns action forces a rescan of the provided LUNs and updates the database with the new size if required.
Example 12.19. Refreshing the LUN Size
POST /ovirt-engine/api/storagedomains/262b056b-aede-40f1-9666-b883eff59d40/refreshluns HTTP/1.1
Accept: application/xml
Content-type: application/xml

13.3. Methods
13.3.1. Creating a New Storage Connection
Creating a new storage connection requires a
POST request.
It is possible to create a new storage connection without adding a storage domain. The host
id or name is optional; providing it will attempt a connection to the storage via the host.
Example 13.2. Creating a New Storage Connection
POST /ovirt-engine/api/storageconnections HTTP/1.1
Accept: application/xml
Content-type: application/xml
<storage_connection>

<path>/export/storagedata/username/data</path>
<host>
<name>Host_Name</name>
</host>
</storage_connection>
13.3.2. Deleting a Storage Connection
Deleting a storage connection requires a
DELETE request. A storage connection can only be deleted if neither storage domain nor LUN disks reference it.
The host
name or id is optional; providing it unmounts the connection from that host.
Example 13.3. Deleting Storage Connection
DELETE /ovirt-engine/api/storageconnections/Storage_Connection_ID HTTP/1.1 Accept: application/xml Content-type: application/xml <host> <name>Host_Name</name> </host>

Updating an existing storage connection requires a
PUT request. The storage domain must be in either maintenance mode or unattached to successfully update the connection.
Providing the host
name or id is optional; if provided, the host attempts a connection to the updated storage details.
Example 13.4. Updating a Storage Connection
PUT /ovirt-engine/api/storageconnections/Storage_Connection_ID HTTP/1.1
Accept: application/xml
Content-type: application/xml
<storage_connection>
<address>updated.example.domain.com</address>
<host>
<name>Host_name</name>
</host>
</storage_connection>
13.3.4. Updating an iSCSI Storage Connection
Updating an existing iSCSI storage connection requires a
PUT request. An iSCSI storage domain must be in maintenance mode or unattached to successfully update the connection.
Example 13.5. Updating a Storage Connection
PUT /ovirt-engine/api/storageconnections/Storage_Connection_ID HTTP/1.1 Accept: application/xml Content-type: application/xml <storage_connection> <port>3456</port> </storage_connection>
13.3.5. Adding New Storage Domain with Existing Storage Connection
Adding a new storage domain with existing storage connection requires a
POST request. This is only applicable with file-based storage domains: NFS, POSIX, and local.
Example 13.6. Adding a New Storage Domain with Existing Storage Connection
POST /ovirt-engine/api/storagedomains HTTP/1.1
Accept: application/xml
Content-type: application/xml
<storage_domain>
<name>New_Domain</name>
<type>data</type>
<storage id="Storage_Connection_ID"/>
<host>
<name>Host_Name</name>
</host>
</storage_domain>
13.3.6. Attaching an Additional Storage Connection to iSCSI Storage
Attaching an additional storage connection to an iSCSI storage domain requires a
POST request.
Example 13.7. Attaching an Additional Storage Connection to iSCSI Storage
POST /ovirt-engine/api/storagedomains/iSCSI_Domain_ID/storageconnections HTTP/1.1 Accept: application/xml Content-type: application/xml <storage_connection id="Storage_Connection_ID"> </storage_connection>
13.3.7. Detaching a Storage Connection from iSCSI Storage
Detaching a storage connection from an iSCSI storage domain requires a
DELETE request.
Example 13.8. Detaching a Storage Connection from iSCSI Storage
DELETE /ovirt-engine/api/storagedomains/iSCSI_Domain_ID/storageconnections/Storage_Connection_ID HTTP/1.1 Accept: application/xml Content-type: application/xml
13.3.8. Defining Credentials to an iSCSI Target
When an iSCSI storage domain is added using the Administration Portal, only a single user name and password can be specified for that domain. However, some setups require that each host in the cluster use a separate user name and password. Specific credentials can be applied to each iSCSI target per host by using the
storageconnectionextensions element.
Example 13.9. Defining credentials to an iSCSI target
POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/storageconnectionextensions HTTP/1.1
Accept: application/xml
Content-type: application/xml
<storageconnectionextension>
<target>iqn.2010.05.com.example:iscsi.targetX</target>
<username>jimmy</username>
<password>p@55w0Rd!</password>
</storageconnectionextension>

14.4. Power Management Elements
The
power_management element provides users with the ability to set a power management configuration, which is required for host fencing. Certain sub-elements are required when configuring power_management.
| Element | Type | Description | Properties |
|---|---|---|---|
type= | fencing device code | A list of valid fencing device codes are available in the capabilities collection. |
|
enabled | Boolean: true or false | Indicates whether power management configuration is enabled or disabled. |
|
address | string | The host name or IP address of the host. |
|
username | string | A valid user name for power management. | |
password | string | A valid, robust password for power management. | |
options | complex | Fencing options for the selected type= specified with the option name="" and value="" strings. | |
agents | complex | Specifies fence agent options when multiple fences are used. Use the order sub-element to prioritize the fence agents. Agents are run sequentially according to their order until the fence action succeeds. When two or more fence agents have the same order, they are run concurrently. Other sub-elements include type, ip, user, password, and options. | |
automatic_pm_enabled | Boolean: true or false | Toggles the automated power control of the host in order to save energy. When set to true, the host will be automatically powered down if the cluster's load is low, and powered on again when required. This is set to true when a host is created, unless disabled by the user. | |
kdump_detection | Boolean: true or false | Toggles whether to determine if kdump is running on the host before it is shut down. When set to true, the host will not shut down during a kdump process. This is set to true when a host has power management enabled, unless disabled by the user. |
The
options element requires a list of option sub-elements. Each option requires a name and type attributes. Certain options are only available for specific fencing types as defined in the capabilities collection.
A new host includes an optional
power_management configuration when POSTing to the host resource. The power_management configuration is updatable using a PUT request.
Example 14.3. An XML representation of a host's power management configuration
<host id="2ab5e1da-b726-4274-bbf7-0a42b16a0fc3"

...
</host>
14.5. Memory Management Elements
The API provides two configuration settings for a host's memory management.
Kernel SamePage Merging (KSM) reduces references to memory pages from multiple identical pages to a single page reference. This helps with optimization for memory density. KSM uses the
ksm element.
Example 14.4. Setting KSM memory management
PUT /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3 HTTP/1.1
Accept: application/xml
Content-Type: application/xml
<host id="2ab5e1da-b726-4274-bbf7-0a42b16a0fc3"
href="/ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3">
<ksm>true</ksm>
</host>
Transparent Hugepage support expands the size of memory pages beyond the standard 4kB limit. This reduces memory consumption and increases host performance. Transparent Hugepage support uses the
transparent_hugepages element.
Example 14.5. Setting Transparent Hugepage memory management
PUT /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3 HTTP/1.1
Accept: application/xml
Content-Type: application/xml
<host id="2ab5e1da-b726-4274-bbf7-0a42b16a0fc3"
href="/ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3">
<transparent_hugepages>true</transparent_hugepages>
</host>
Availability of Transparent Hugepage support is found in the
capabilities collection.
14.6. Methods
14.6.1. Creating a Host
Creation of a new host requires the
name, address and root_password elements.
Example 14.6. Creating a host
POST /ovirt-engine/api/hosts HTTP/1.1
Accept: application/xml
Content-type: application/xml
<host>
<name>host2</name>
<address>host2.example.com</address>
<root_password>p@55w0Rd!</root_password>
</host>
The
root_password element is only included in the client-provided initial representation and is not exposed in the representations returned from subsequent requests.
14.6.2. Updating a Host
The
name, description, cluster, power_management, transparent_hugepages and ksm elements are updatable post-creation.
Example 14.7. Updating a host
POST /ovirt-engine/api/hosts/00000000-0000-0000-0000-000000000000 HTTP/1.1
Accept: application/xml
Content-type: application/xml
<host>
<name>host3</name>
</host>
14.6.3. Removing a Host
Removal of a host requires a
DELETE request.
Example 14.8. Removing a host
DELETE /ovirt-engine/api/hosts/00000000-0000-0000-0000-000000000000 HTTP/1.1 HTTP/1.1 204 No Content
14.7. Sub-Collections
14.7.1. Host Network Attachments Sub-Collection

</network_attachment>
When attaching a network to a host, the
network and host_nic elements are required, with either an id or a name. The host_nic ID can refer to either an unused network interface card or a bond.
Example 14.10. Attach a network to a host
POST /ovirt-engine/api/hosts/00000000-0000-0000-0000-000000000000/nics/00000000-0000-0000-0000-000000000000/networkattachments HTTP/1.1
Accept: application/xml
Content-type: application/xml
<network_attachment>
<network id="00000000-0000-0000-0000-000000000000"/>
<host_nic id="00000000-0000-0000-0000-000000000000"/>
</network_attachment>
The
host_nic, ip_address_assignments, and properties elements are updatable post-creation. Changing the host_nic ID moves the network to a different network interface card.
Example 14.11. Modifying a host network attachment
PUT /ovirt-engine/api/hosts/00000000-0000-0000-0000-000000000000/nics/00000000-0000-0000-0000-000000000000/networkattachments/00000000-0000-0000-0000-000000000000 HTTP/1.1

</network_attachment>
Detach a network from the host with a
DELETE request on the network attachment.
Example 14.12. Detach a network from a host
DELETE /ovirt-engine/api/hosts/00000000-0000-0000-0000-000000000000/nics/00000000-0000-0000-0000-000000000000/networkattachments/00000000-0000-0000-0000-000000000000 HTTP/1.1 Accept: application/xml Content-type: application/xml HTTP/1.1 204 No Content

Remove a network interface with a
DELETE request.
DELETE /ovirt-engine/api/hosts/00000000-0000-0000-0000-000000000000/nics/ 00000000-0000-0000-0000-000000000000 HTTP/1.1 HTTP/1.1 204 No Content
14.7.2.2. Bonded Interfaces
A bonded interface is represented as a
host_nic resource containing a bonding element.
| Element | Type | Description | Properties |
|---|---|---|---|
options | complex | A list of option elements for a bonded interface. Each option contains property name and value attributes. |
[a]
|
slaves | complex | A list of slave host_nic id= elements for a bonded interface. |
[b]
|
[a]
Only required when adding bonded interfaces. Other interfaces are read-only and cannot be added.
[b]
Only required when adding bonded interfaces. Other interfaces are read-only and cannot be added.
| |||
An API user creates a new bond when creating a new
host_nic (POST) or updating a host_nic (PUT). Use either the id or name elements to identify the slave host_nic elements. When adding a new network interface, the name and network elements are required. Identify the network element with the id attribute or name element.
Example 14.14. Creating a bonded interface

fence action. The capabilities lists available fence_type options.
Example 14.31. Action to fence a host
POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/fence
Accept: application/xml
Content-Type: application/xml
<action>
<fence_type>start</fence_type>
</action>
14.8.5. Deactivate Host Action
Deactivate the host to perform maintenance tasks.
Example 14.32. Action to deactivate a host
POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/deactivate HTTP/1.1 Accept: application/xml Content-type: application/xml <action/>
14.8.6. Host iSCSI Login Action
The
iscsilogin action enables a host to login to an iSCSI target. Logging into a target makes the contained LUNs available in the host_storage collection.
Example 14.33. Action to enable a host to login to iSCSI target
POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/iscsilogin HTTP/1.1
Accept: application/xml
Content-Type: application/xml
<action>
<iscsi>
<address>mysan.example.com</address>
<target>iqn.2009-08.com.example:mysan.foobar</target>
<username>jimmy</username>
<password>s3kr37</password>
</iscsi>
</action>
14.8.7. Host iSCSI Discover Action
The
iscsidiscover action enables an iSCSI portal to be queried for its list of targets.
Example 14.34. Action to query a list of targets for iSCSI portal
POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/iscsidiscover HTTP/1.1
Accept: application/xml
Content-Type: application/xml

<iscsi>
<address>mysan.example.com</address>
<port>3260</port>
</iscsi>
</action>
14.8.8. Commit Host Network Configuration Action
An API user commits the network configuration to persist a host network interface attachment or detachment, or persist the creation and deletion of a bonded interface.
Example 14.35. Action to commit network configuration
POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/commitnetconfig HTTP/1.1 Accept: application/xml Content-type: application/xml <action/>
Important
Networking configuration is only committed after the Manager has established that host connectivity is not lost as a result of the configuration changes. If host connectivity is lost, the host requires a reboot and automatically reverts to the previous networking configuration.
14.8.9. Setting SPM
Manually set a host as the Storage Pool Manager (SPM).
Example 14.36. Action to Set Host as SPM
POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/forceselectspm HTTP/1.1 Accept: application/xml Content-type: application/xml <action/>
Chapter 15. Virtual Machines
15.1. Virtual Machine Elements
The
vms collection provides information about virtual machines in a Red Hat Virtualization environment. An API user accesses this information through the rel="vms" link obtained from the entry point URI.
Additional information can be retrieved for
GET requests using the All-Content: true header.
The following table shows specific elements contained in a virtual machine resource representation.
| Element | Type | Description | Properties |
|---|---|---|---|
link rel="applications" | relationship | A link to the applications sub-collection for virtual machine resources, which shows the applications installed on the virtual machine. | |
link rel="disks" | relationship | A link to the disks sub-collection for virtual machine resources. | |
link rel="nics" | relationship | A link to the nics sub-collection for virtual machine resources. | |
link rel="numanodes" | relationship | A link to the numanodes sub-collection for virtual machine resources. | |
link rel="cdroms" | relationship | A link to the cdroms sub-collection for virtual machine resources. | |
link rel="snapshots" | relationship | A link to the snapshots sub-collection for virtual machine resources. | |
link rel="tags" | relationship | A link to the tags sub-collection for virtual machine resources. | |
link rel="permissions" | relationship | A link to the permissions sub-collection for virtual machine permissions. | |
link rel="statistics" | relationship | A link to the statistics sub-collection for virtual machine resources. |
|
link rel="reporteddevices" |
relationship
|
A link to the
reporteddevices sub-collection for virtual machine resources.
| |
link rel="watchdogs" |
relationship
|
A link to the
watchdogs sub-collection for virtual machine resources.
| |
link rel="sessions" |
relationship
|
A link to the
sessions sub-collection for virtual machine resources.
| |
type | enumerated | The virtual machine type. A list of enumerated values are available in capabilities. |
|
status | See below | The virtual machine status. |
|
memory | integer | The amount of memory allocated to the guest in bytes. | |
cpu | complex |
Defines CPU details for the virtual machine. The
topology sub-element sets number of logical sockets available to the guest and the number of cores per socket. The total cores available to the virtual machine equals the number of sockets multiplied by the cores per socket.
The
cputune sub-element maps virtual CPUs to physical host CPUs using a series of vcpupin elements. Each vcpupin elements contains a virtual CPU attribute (vcpu) and an attribute to define which physical to use (cpuset). Set the cpuset to either a single CPU (cpuset="0"), multiple CPUs (cpuset="0,2"), a CPU range (cpuset="0-3") or a CPU range with exclusion (cpuset="0-3,^2").
The
cpu_mode sub-element defines how closely the virtual CPU relates to the host CPU. It has three values: custom is the default if no mode is given, host_model copies the host CPU as best as libvirt can understand, and host_passthrough passes all aspects of the host to the guest, even those that libvirt does not recognize. However, host_passthrough will prevent migration of that virtual machine.
| |
os type= | string, e.g. RHEL5 or WindowsXP | The guest operating system type. | |
os boot dev= | enumerated | A list of boot devices described by a dev attribute on a boot element. A list of enumerated values are available in capabilities. | |
os kernel | string | A path to a kernel image the virtual machine is configured to boot. This option supports booting a Linux kernel directly rather than through the BIOS bootloader. | |
os initrd | string | A path to an initrd image to be used with the previously specified kernel. This option supports booting a Linux kernel directly rather than through the BIOS bootloader. | |
os cmdline | string | A kernel command line parameter string to be used with the defined kernel. This option supports booting a Linux kernel directly rather than through the BIOS bootloader. | |
high_availability | complex | Set enabled to true if the virtual machine should be automatically restarted if the virtual machine or its host crashes. A priority element controls the order in which virtual machines are re-started. | |
display | complex |
The display
type (either vnc or spice), port, and the number of monitors. The allow_reconnect Boolean value specifies if a client can reconnect to the machine via display.
The
smartcard_enabled sub-element is a Boolean (true or false) to specify if a Smartcard attached to a client is passed through to a virtual machine. The default is false.
| |
cluster id= | GUID | A reference to the virtual machine's host cluster. |
|
template id= | GUID | A reference to the template on which this virtual machine is based. |
|
domain id= | GUID | A reference to the virtual machine's domain. |
|
start_time | xsd:dateTime format: YYYY-MM-DDThh:mm:ss | The date and time at which this virtual machine was started. |
|
stop_time | xsd:dateTime format: YYYY-MM-DDThh:mm:ss | The date and time at which this virtual machine was stopped. |
|
creation_time | xsd:dateTime format: YYYY-MM-DDThh:mm:ss | The date and time at which this virtual machine was created. |
|
origin | One of rhev, ovirt, vmware or xen | The system from which this virtual machine originated. |
|
stateless | Boolean: true or false | true if the virtual machine is stateless. A stateless virtual machine contains a snapshot of its disk image taken at boot and deleted at shutdown. This means state changes do not persist after a reboot. | |
delete_protected | Boolean: true or false | If set to true, the virtual machine cannot be deleted. | |
sso | string | A reference to the method of single sign-on for the virtual machine. Includes a method element with an ip attribute. | |
placement_policy | complex | Sets the placement policy for virtual machine migration. Requires a default host= and an affinity (one of migratable, user_migratable or pinned). Leave the host element empty to set no preferred host. Use multiple host elements to specify a subset of preferred hosts within a cluster. | |
memory_policy | complex | Sets the memory policy for virtual machines. Defines the minimum amount of guaranteed memory on a host in order for the virtual machine to run. | |
quota id= | GUID | Sets a quota for the virtual machine. | |
custom_properties | complex | A set of user-defined environment variable passed as parameters to custom scripts. Each custom_property contains name and value attributes. A list of enumerated values are available in capabilities. | |
usb | complex | Defines the USB policy for a virtual machine. Requires an enabled element set to a Boolean value and a type element set to either native or legacy.
Important
The Legacy USB option has been deprecated and will be removed in Red Hat Virtualization 4.1.
| |
migration_downtime | integer | Represents the maximum number of milliseconds the virtual machine can be down during live migration. A value of 0 means that the VDSM default will be used. | |
cpu_profile id= | GUID | A reference to the virtual machine's cpu profile. | |
next_run_configuration | Boolean: true or false | true if changes to the virtual machine's configuration will be applied when the virtual machine is next restarted. | |
numa_tune_mode | string | Reference to the mode of memory allocation (interleave, strict, or preferred) of the host NUMA node. | |
guest_info | complex | A reference to the guest client information. Includes an ip element with an address= attribute. |
|
vmpool | complex | A reference to the virtual machine pool. This element only appears for virtual machines part of a pool. |
|
timezone | tz database format: Area/Location | The Sysprep timezone setting for a Windows virtual machine. | |
domain | complex | The Sysprep domain setting for a Windows virtual machine. Requires a name from the domains collection. | |
initialization | complex |
Defines a list of values applied to the virtual machine on boot using Cloud-Init for Linux-based virtual machines, or Sysprep for Windows-based virtual machines.
| |
payloads | complex |
Defines a set of
payload elements to deliver content to a virtual machine upon boot. Each payload requires a type attribute, either cdrom or floppy, and a set of file elements. Within each file element is a name element that specifies the name and location of the file, and a content element that defines the content to deliver to the file.
The
payloads element is used by the cloud-init feature. When cloud-init is used to configure a virtual machine, a payload is automatically created with the type attribute set to cd-rom and two file sub-elements, openstack/latest/meta_data.json and openstack/latest/user_data, which pass configuration parameters to the virtual machine.
|
The
status contains one of the following enumerative values: unassigned, down, up, powering_up, powered_down, paused, migrating_from, migrating_to, unknown, not_responding, wait_for_launch, reboot_in_progress, saving_state, restoring_state, suspended, image_illegal, image_locked or powering_down. These states are listed in vm_states under capabilities.

15.3. XML Representation of Additional OVF Data for a Virtual Machine
Use a
GET request for a virtual machine with the All-Content: true header to include additional OVF data with the representation of the virtual machine.
The
Accept header defaults to application/xml if left blank, and the data is represented with HTML entities so as not to interfere with the XML tags. Specifying the Accept: application/json header will return the data in standard XML tagging. This example representation has been formatted from its standard block format to improve legibility.

15.5. Methods
15.5.1. Creating a Virtual Machine
Creating a new virtual machine requires the
name, template, and cluster elements. Identify the template and cluster elements with the id attribute or name element. Identify the CPU profile ID with the cpuprofiles attribute.
Example 15.4. Creating a virtual machine with 512 MB that boots from CD-ROM
POST /ovirt-engine/api/vms HTTP/1.1
Accept: application/xml
Content-type: application/xml
<vm>
<name>vm2</name>
<description>Virtual Machine 2</description>
<type>desktop</type>
<memory>536870912</memory>
<cluster>
<name>default</name>
</cluster>
<template>
<name>Blank</name>
</template>
<os>
<boot dev="cdrom"/>
</os>
<cdroms>
<cdrom>
<file id="example_windows_7_x64_dvd_u_677543.iso"/>
</cdrom>
</cdroms>
<cpu_profile id="0000001a-001a-001a-001a-00000000035e"/>
</vm>
Example 15.5. Creating a virtual machine with 512 MB that boots from a virtual hard disk
POST /ovirt-engine/api/vms HTTP/1.1
Accept: application/xml
Content-type: application/xml
<vm>
<name>vm2</name>
<description>Virtual Machine 2</description>
<type>desktop</type>
<memory>536870912</memory>
<cluster>
<name>default</name>
</cluster>
<template>
<name>Blank</name>
</template>
<os>
<boot dev="hd"/>
</os>
<cpu_profile id="0000001a-001a-001a-001a-00000000035e"/>
</vm>
Note
Memory in the previous example is converted to bytes using the following formula:
512MB * 1024 2 = 536870912 bytes
15.5.2. Updating a Virtual Machine
The
name, description, cluster, type, memory, cpu, os, high_availability, display, timezone, domain, stateless, placement_policy, memory_policy, usb, payloads, origin and custom_properties elements are updatable post-creation.
Example 15.6. Updating a virtual machine to contain 1 GB of memory
PUT /ovirt-engine/api/vms/082c794b-771f-452f-83c9-b2b5a19c0399 HTTP/1.1
Accept: application/xml
Content-type: application/xml
<vm>
<memory>1073741824</memory>
</vm>
Note
Memory in the previous example is converted to bytes using the following formula:
1024MB * 1024 2 = 1073741824 bytes
Note
Memory hot plug is supported in Red Hat Virtualization. If the virtual machine's operating system supports memory hot plug, you can use the example above to increase memory while the virtual machine is running.
Example 15.7. Hot plugging vCPUs
Add virtual CPUs to a running virtual machine without having to reboot it. In this example, the number of sockets is changed to 2.
PUT /ovirt-engine/api/vms/082c794b-771f-452f-83c9-b2b5a19c0399 HTTP/1.1
Accept: application/xml
Content-type: application/xml
<vm>
<cpu>
<topology sockets="2" cores="1"/>
</cpu>
</vm>Note
CPU hot unplug is currently not supported in Red Hat Virtualization.
Example 15.8. Pinning a virtual machine to multiple hosts
A virtual machine that is pinned to multiple hosts cannot be live migrated, but in the event of a host failure, any virtual machine configured to be highly available is automatically restarted on one of the other hosts to which the virtual machine is pinned. Multi-host pinning can be used to restrict a virtual machine to hosts with, for example, the same hardware configuration.
PUT /ovirt-engine/api/vms/082c794b-771f-452f-83c9-b2b5a19c0399 HTTP/1.1
Accept: application/xml
Content-type: application/xml
<vm>
<high_availability>
<enabled>true</enabled>
<priority>1</priority>
</high_availability>
<placement_policy>
<hosts>
<host><name>Host1</name></host>
<host><name>Host2</name></host>
</hosts>
<affinity>pinned</affinity>
</placement_policy>
</vm>15.5.3. Removing a Virtual Machine
Removal of a virtual machine requires a
DELETE request.
Example 15.9. Removing a virtual machine
DELETE /ovirt-engine/api/vms/082c794b-771f-452f-83c9-b2b5a19c0399 HTTP/1.1 HTTP/1.1 204 No Content
15.5.4. Removing a Virtual Machine but not the Virtual Disk
Detach the virtual disk prior to removing the virtual machine. This preserves the virtual disk. Removal of a virtual machine requires a
DELETE request.
Example 15.10. Removing a virtual machine
DELETE /ovirt-engine/api/vms/082c794b-771f-452f-83c9-b2b5a19c0399 HTTP/1.1
Accept: application/xml
Content-type: application/xml
<action>
<vm>
<disks>
<detach_only>true</detach_only>
</disks>
</vm>
</action>
15.6. Sub-Collections
15.6.1. Disks Sub-Collection
15.6.1.1. Disks Sub-Collection
The
disks sub-collection represents all virtual hard disk devices on a virtual machine. A disk representation contains the following elements:
| Element | Type | Description | Properties |
|---|---|---|---|
link rel="statistics" | relationship | A link to the statistics sub-collection for a virtual machine's disk statistics. |
|
link rel="permissions" | relationship | A link to the permissions sub-collection. |
|
alias | string | The unique identifier for the disk. Use alias instead of name. | |
image_id | string | A reference to the virtual machine image stored on the defined storage domain. | |
storage_domains | complex | The storage domains associated with this disk. Each storage_domain element contains an id attribute with the associated storage domain's GUID. Update this element with POST to perform live migration of a disk from one data storage domain to another. |
[a] |
size | integer | Size of the disk in bytes. Deprecated; replaced by provisioned_size. |
|
provisioned_size | integer | The provisioned size of the disk in bytes. |
|
actual_size | integer | Actual size of the disk in bytes. |
|
status | One of illegal, invalid, locked or ok | The status of the disk device. These states are listed in disk_states under capabilities. |
|
interface | enumerated | The type of interface driver used to connect to the disk device. A list of enumerated values is available in capabilities. | |
format | enumerated | The underlying storage format. A list of enumerated values is available in capabilities. Copy On Write (COW) allows snapshots, with a small performance overhead. Raw does not allow snapshots, but offers improved performance. |
|
sparse | Boolean: true or false | true if the physical storage for the disk should not be preallocated. |
|
bootable | Boolean: true or false | true if this disk is to be marked as bootable. | |
shareable | Boolean: true or false | true to share the disk with multiple virtual machines. | |
wipe_after_delete | Boolean: true or false | true if the underlying physical storage for the disk should be zeroed when the disk is deleted. This increases security but is a more intensive operation and may prolong delete times. | |
propagate_errors | Boolean: true or false | true if disk errors should not cause virtual machine to be paused and, instead, disk errors should be propagated to the guest OS. | |
vm id= | GUID | The ID of the containing virtual machine. |
|
quota id= | GUID | Sets a quota for the disk. | |
lun_storage | complex | A reference to a direct LUN mapping for storage usage. Requires a logical_unit element that contains iSCSI or FCP device details. |
|
active | Boolean | Defines if the disk is connected to the virtual machine. |
|
read_only | Boolean | Defines if the disk is read-only. | |
link rel="disk_profile" | relationship | A link to the disk_profile sub-collection. | |
[a]
This element is only required if the disk is being added to a virtual machine and not created from a virtual machine template.

Important
Search queries for virtual disks based upon disk name require the
alias search parameter instead of name.
15.6.1.3. Disk Statistics Sub-Collection
Each virtual machine's disk exposes a
statistics sub-collection for disk-specific statistics. Each statistic contains the following elements:
| Element | Type | Description |
|---|---|---|
name | string | The unique identifier for the statistic entry. |
description | string | A plain text description of the statistic. |
unit | string | The unit or rate to measure the statistical values. |
type | One of GAUGE or COUNTER | The type of statistic measures. |
values type= | One of INTEGER or DECIMAL | The data type for the statistical values that follow. |
value | complex | A data set that contains datum. |
datum | see values type | An individual piece of data from a value. |
disk id= | relationship | A relationship to the containing disk resource. |
The following table lists the statistic types for virtual disks.
|
Name
|
Description
|
|---|---|
data.current.read |
The data transfer rate in bytes per second when reading from the disk.
|
data.current.write |
The data transfer rate in bytes per second when writing to the disk.

</statistics>
Note
This
statistics sub-collection is read-only.
15.6.1.4. Floating Disk Attach and Detach Actions
Attach a disk from the main
rel="disks" collection using a POST request on the virtual machine's disks sub-collection. Include the id of the disk to attach.
Example 15.20. Attach a floating disk
POST /ovirt-engine/api/vms/082c794b-771f-452f-83c9-b2b5a19c0399/disks HTTP/1.1 Accept: application/xml Content-type: application/xml <disk id="d135f1c5-b5e1-4238-9381-b3277f5a3742"> </disk>
Detach a disk from a virtual machine's
disks sub-collection using a DELETE request on the disk resource but ensure to include a detach Boolean element so the disk is not destroyed.
Example 15.21. Detach a disk from a virtual machine
DELETE /ovirt-engine/api/vms/082c794b-771f-452f-83c9-b2b5a19c0399/disks/

Note
Virtual machines only contain a single CD-ROM device.
15.6.5. Snapshots Sub-Collection
15.6.5.1. Snapshots Sub-Collection
A virtual machine saves and restores disk state as a number of snapshots. These are represented and managed through a
rel="snapshot" sub-collection that behaves similar to other collections.
Each virtual machine snapshot is represented with an individual
snapshot element that contains the following sub-elements:
| Element | Type | Description | Properties |
|---|---|---|---|
vm id= | GUID | The ID and URI of the virtual machine to which this snapshot pertains. |
|
link rel="restore" | relationship | A link to restore the snapshot of the virtual machine. |
|
link rel="prev" | relationship | A link to the previous snapshot of this virtual machine. |
|
type | string | The type of the snapshot. For example, active or regular. |
|
date | xsd:dateTime format: YYYY-MM-DDThh:mm:ss | The date and time at which the snapshot was created. |
|
snapshot_status | string | The current status of the snapshot. |
|
persist_memorystate | Boolean | Defines whether the snapshot also includes the state of the memory of the virtual machine at the time the snapshot was taken. |
|
Note
It is not possible to modify snapshot elements using
PUT.
Example 15.39. An XML representation of a virtual machine snapshot
<snapshot id="00000000-0000-0000-0000-000000000000"

<date>2010-08-16T14:24:29</date>
<snapshot_status>ok</snapshot_status>
<persist_memorystate>false</persist_memorystate>
</snapshot>
Use a
GET request for a virtual machine snapshot with the All-Content: true header to include additional OVF data with the representation of the snapshot.
The
Accept header defaults to application/xml if left blank, and the data is represented with HTML entities so as not to interfere with the XML tags. Specifying the Accept: application/json header will return the data in standard XML tagging. This example representation has been formatted from its standard block format to improve legibility.
Example 15.40. XML representation of additional ovf data for a snapshot

You can create a snapshot of a virtual machine that is running (a live snapshot) or shut down by using the
POST method:
Example 15.41. Creating a Virtual Machine Snapshot
POST /ovirt-engine/api/vms/00000000-0000-0000-0000-000000000000/snapshots/ HTTP/1.1 Accept: application/xml Content-type: application/xml <snapshot> <description>Snapshot description</description> </snapshot>
Important
Before taking a live snapshot of a virtual machine that uses OpenStack Volume (Cinder) disks, you must freeze and thaw the guest filesystem manually. See Section 15.7.14, “Freeze Virtual Machine Filesystems Action” and Section 15.7.15, “Thaw Virtual Machine Filesystems Action” for more information.
You can restore a virtual machine snapshot using the
rel="restore" action link in the snapshot representation:
Example 15.42. Restoring a Virtual Machine Snapshot
POST /ovirt-engine/api/vms/00000000-0000-0000-0000-000000000000/snapshots/00000000-0000-0000-0000-000000000000/restore HTTP/1.1 Accept: application/xml Content-type: application/xml <action/>
15.6.5.2. Clone a Virtual Machine from a Snapshot
API provides a function to create virtual machines from a snapshot of a previous machine. API users create a new virtual machine while retaining the original virtual machine with all snapshots intact.
Creation of a virtual machines from a snapshot requires an additional
snapshots element to a standard representation of a virtual machine, which a user sends in a POST request to the vms collection.
The
snapshots element contains a snapshot id= element to define the specific snapshot to use as a basis for the virtual machine.
Example 15.43. Clone Virtual Machine from Snapshot
POST /ovirt-engine/api/vms HTTP/1.1
Accept: application/xml
Content-type: application/xml
<vm>
...
<snapshots>
<snapshot id="3f68ee63-0016-4f8c-9b8a-11d9f28f7c9e"/>
</snapshots>
...
</vm>
15.6.6. Statistics Sub-Collection
Each virtual machine resource exposes a
statistics sub-collection for virtual machine-specific statistics. Each statistic contains the following elements:
| Element | Type | Description |
|---|---|---|
name | string | The unique identifier for the statistic entry. |
description | string | A plain text description of the statistic. |
unit | string | The unit or rate to measure the statistical values. |
type | One of GAUGE or COUNTER | The type of statistic measures. |
values type= | One of INTEGER or DECIMAL | The data type for the statistical values that follow. |
value | complex | A data set that contains datum. |
datum | see values type | An individual piece of data from a value. |
vm id= | relationship | A relationship to the containing vm resource. |
The following table lists the statistic types for virtual machines.
|
Name
|
Description
|
|---|---|
memory.installed |
Total memory in bytes allocated for the virtual machine's use.
|
memory.used |
Current memory in bytes used by the virtual machine.
|
cpu.current.guest |
Percentage of CPU used by the guest.
|
cpu.current.hypervisor |
Percentage of CPU overhead on the hypervisor.
|
cpu.current.total |
Total percentage of the current CPU in use.
|
Example 15.44. An XML representation of a virtual machine's statistics sub-collection

</statistic>
...
</statistics>
Note
A virtual machine's
statistics sub-collection is read-only.
15.6.7. Displaying Virtual Machine Session Information
Submit a
GET request for a virtual machine and use the session sub-collection to view the session information for the user that initiated the SPICE console session and the user logged in to the virtual machine.
The
session information of a virtual machine is listed as a sub-collection:
Example 15.45. Displaying the session information of a virtual machine
GET /ovirt-engine/api/roles/a1a701f1-aa06-4f02-af17-158be31489b3/sessions HTTP/1.1

15.7. Actions
15.7.1. Start Virtual Machine Action
The start action launches a stopped, shutdown, or suspended virtual machine.
Example 15.46. Action to start a virtual machine
POST /ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720/start HTTP/1.1 Accept: application/xml Content-type: application/xml <action/>
The start action allows a
vm element to be provided as a parameter. If a vm element is provided, the virtual machine uses the values from the provided element and overrides system settings at start time. Using the start action with the vm element in REST API is equivalent to using the Run Once window in the Administration or User Portal. These settings persist until a user stops the virtual machine. Examples of these elements include os, domain, placement_policy, cdroms, stateless and display type.
Example 15.47. Action to start a virtual machine with overridden parameters
POST /ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720/start HTTP/1.1
Accept: application/xml
Content-type: application/xml

</domain>
<placement_policy>
<host id="02447ac6-bcba-448d-ba2b-f0f453544ed2"/>
</placement_policy>
</vm>
</action>
Note
- The
domainelement is used for Windows systems only for overriding parameters on boot with thestartaction. Thedomainelement determines the domain that the Windows virtual machine joins. If the domain does not exist in thedomainscollection, this element requires additionaluserauthentication details, including auser_nameandpassword. If the domain exists in thedomainscollection, the action requires no additionaluserauthentication details. - The CD image and floppy disk file must be available in the ISO domain already. If not, use the ISO uploader tool to upload the files. See The ISO Uploader Tool for more information.
15.7.2. Start Virtual Machine with Cloud-Init Action
Cloud-Init is a tool for automating the initial setup of virtual machines. You can use the tool to configure the host name, network interfaces, the DNS service, authorized keys, and set user names and passwords. You can also use the
custom_script tag to specify a custom script to run on the virtual machine when it boots.
Note
The
cloud-init element can only be used to start virtual machines with the cloud-init package installed. When the cloud-init element is used, any element within the initialization element but outside the cloud-init element will be ignored.
Example 15.48. Action to start a virtual machine using Cloud-Init
This example shows you how to start a virtual machine using the Cloud-Init tool to set the host name, change the root password, set a static IP for the
eth0 interface, configure DNS, and add an SSH key for the root user.

15.7.3. Stop Virtual Machine Action
The stop action forces a virtual machine to power-off.
Example 15.49. Action to stop a virtual machine
POST /ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720/stop HTTP/1.1 Accept: application/xml Content-type: application/xml <action/>
15.7.4. Shutdown Virtual Machine Action
The shutdown action sends a shutdown request to a virtual machine.
Example 15.50. Action to send a shutdown request to a virtual machine
POST /ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720/shutdown HTTP/1.1 Accept: application/xml Content-type: application/xml <action/>
15.7.5. Suspend Virtual Machine Action
The suspend action saves the virtual machine state to disk and stops it. Start a suspended virtual machine and restore the virtual machine state with the start action.
Example 15.51. Action to save virtual machine state and suspend the machine
POST /ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720/suspend HTTP/1.1 Accept: application/xml Content-type: application/xml <action/>
15.7.6. Reboot Virtual Machine Action
The reboot action sends a reboot request to a virtual machine.
Example 15.52. Action to send a reboot request to a virtual machine
POST /ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720/reboot HTTP/1.1 Accept: application/xml Content-type: application/xml <action/>
15.7.7. Enable user logon to access a virtual machine from an external console
The logon action enables users to access a virtual machine from consoles outside of the Red Hat Virtualization environment.
This action requires the rhevm-guest-agent-gdm-plugin and the rhevm-guest-agent-pam-module packages to be installed and the
ovirt-guest-agent service to be running on the virtual machine.
Users require the appropriate user permissions for the virtual machine in order to access the virtual machine from an external console.
Example 15.53. Logging onto a virtual machine
POST /ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720/logon HTTP/1.1
Content-Type: application/json
Content-Length: 2
{}
15.7.8. Detach Virtual Machine from Pool Action
The detach action detaches a virtual machine from a pool.
Example 15.54. Action to detach a virtual machine
POST /ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720/detach HTTP/1.1 Accept: application/xml Content-type: application/xml <action/>
15.7.9. Migrate Virtual Machine Action
The migrate action migrates a virtual machine to another physical host. The destination
host element is an optional element as Red Hat Virtualization Manager automatically selects a default host for migration. If an API user requires a specific host, the user can specify the host with either an id or name parameter.
Example 15.55. Action to migrate a virtual machine to another host
POST /ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720/migrate HTTP/1.1
Accept: application/xml
Content-type: application/xml
<action>
<host id="2ab5e1da-b726-4274-bbf7-0a42b16a0fc3"/>
</action>
15.7.10. Cancel Virtual Machine Migration Action
The cancel migration action stops any migration of a virtual machine to another physical host.
Example 15.56. Action to cancel migration of a virtual machine to another host
POST /ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720/cancelmigration HTTP/1.1 Accept: application/xml Content-type: application/xml <action/>
15.7.11. Export Virtual Machine Action
Note
The export storage domain is deprecated. Storage data domains can be unattached from a data center and imported to another data center in the same environment, or in a different environment. Virtual machines, floating virtual disk images, and templates can then be uploaded from the imported storage domain to the attached data center. See the Importing Existing Storage Domains section in the Red Hat Virtualization Administration Guide for information on importing storage domains.
The export action exports a virtual machine to an
export storage domain. A destination storage domain must be specified with a storage_domain reference.
The export action reports a failed action if a virtual machine of the same name exists in the destination domain. Set the
exclusive parameter to true to change this behavior and overwrite any existing virtual machine.
If snapshots of the virtual machine are not included with the exported virtual machine, set the
discard_snapshots parameter to true.
Example 15.57. Action to export a virtual machine to an export storage domain
POST /ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720/export HTTP/1.1
Accept: application/xml
Content-type: application/xml
<action>
<storage_domain>
<name>export1</name>
</storage_domain>
<exclusive>true</exclusive>
<discard_snapshots>true</discard_snapshots>
</action>
15.7.12. Virtual Machine Ticket Action
The ticket action generates a time-sensitive authentication token for accessing a virtual machine's display. The client-provided
action optionally includes a ticket representation containing a value (if the token string needs to take on a particular form) and/or an expiry time in minutes. In any case, the response specifies the actual ticket value and expiry used.
Example 15.58. Action to generate authentication token for a virtual machine

15.7.13. Force Remove Virtual Machine Action
An API user forces the removal of a faulty virtual machine with the
force action. This action requires a DELETE method. The request body contains an action representation with the force parameter set to true. The request also requires an additional Content-type: application/xml header to process the XML representation in the body.
Example 15.59. Force remove action on a virtual machine
DELETE /ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720 HTTP/1.1
Accept: application/xml
Content-type: application/xml
<action>
<force>true</force>
</action>
15.7.14. Freeze Virtual Machine Filesystems Action
The
freezefilesystems action freezes a virtual machine's filesystems using the QEMU guest agent when taking a live snapshot of a running virtual machine. Normally, this is done automatically by the Manager, but this must be executed manually with the REST API for virtual machines using OpenStack Volume (Cinder) disks.
Freezing the filesystems on the guest operating system ensures a consistent snapshot. Once the snapshot is finished, the guest filesystems must then be thawed. On virtual machines not using a OpenStack Volume disk, the freezing and thawing actions can also be invoked manually using the REST API, which can be useful in the case of a failure during the snapshot process.
Example 15.60. Action to freeze a virtual machine's filesystems
POST /ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720/freezefilesystems HTTP/1.1 Accept: application/xml Content-type: application/xml <action/>
For more information on snapshots, see Section 15.6.5.1, “Snapshots Sub-Collection” or the Snapshots section in the Red Hat Virtualization Virtual Machine Management Guide.
15.7.15. Thaw Virtual Machine Filesystems Action
The
thawfilesystems action thaws a virtual machine's filesystems using the QEMU guest agent when taking a live snapshot of a running virtual machine. Normally, this is done automatically by the Manager, but this must be executed manually with the REST API for virtual machines using OpenStack Volume (Cinder) disks.
Freezing the filesystems on the guest operating system ensures a consistent snapshot. Once the snapshot is finished, the guest filesystems must then be thawed. On virtual machines not using a OpenStack Volume disk, the freezing and thawing actions can also be invoked manually using the REST API, which can be useful in the case of a failure during the snapshot process. For example, if the virtual machine became unresponsive during thaw, you can execute the thaw operation again manually; otherwise the virtual machine may remain unresponsive.
Example 15.61. Action to thaw a virtual machine's filesystems
POST /ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720/thawfilesystems HTTP/1.1 Accept: application/xml Content-type: application/xml <action/>
For more information on snapshots, see Section 15.6.5.1, “Snapshots Sub-Collection” or the Snapshots section in the Red Hat Virtualization Virtual Machine Management Guide.
Chapter 16. Floating Disks
16.1. Floating Disk Elements
The
disks collection provides information about all disks in a Red Hat Virtualization environment. A user attaches and detaches disks from any virtual machine and floats them between virtual machines. An API user accesses this information through the rel="disks" link obtained from the entry point URI.
The following table shows specific elements contained in a
disks resource representation.
| Element | Type | Description | Properties |
|---|---|---|---|
link rel="statistics" | relationship | A link to the statistics sub-collection for a virtual machine's disk statistics. |
|
image_id | GUID | A reference to the virtual machine image stored on the defined storage domain. |
|
storage_domains | Complex | The storage domains associated with this disk. Each storage_domain element contains an id attribute with the associated storage domain's GUID. Update this element with POST to perform live migration of a disk from one data storage domain to another. |
|
size | integer | Size of the disk in bytes. |
|
provisioned_size | integer | The provisioned size of the disk in bytes. |
|
actual_size | integer | Actual size of the disk in bytes. |
|
status | One of illegal, invalid, locked or ok | The status of the disk device. These states are listed in disk_states under capabilities. |
|
interface | enumerated | The type of interface driver used to connect to the disk device. A list of enumerated values is available in capabilities. | |
format | enumerated | The underlying storage format. A list of enumerated values is available in capabilities. Copy On Write (COW) allows snapshots, with a small performance overhead. Raw does not allow snapshots, but offers improved performance. |
|
sparse | Boolean: true or false | true if the physical storage for the disk should not be preallocated. |
|
bootable | Boolean: true or false | true if this disk is to be marked as bootable. | |
shareable | Boolean: true or false | true to share the disk with multiple virtual machines. | |
wipe_after_delete | Boolean: true or false | true if the underlying physical storage for the disk should be zeroed when the disk is deleted. This increases security but is a more intensive operation and may prolong delete times. | |
propagate_errors | Boolean: true or false | true if disk errors should not cause virtual machine to be paused and, instead, disk errors should be propagated to the guest OS. | |
quota id= | GUID | Sets a quota for the disk. | |
lunStorage | complex | A reference to a direct LUN mapping for storage usage. Requires a storage element that contains iSCSI or FCP device details. |
|
active | Boolean | Defines if the disk is connected to the virtual machine. |
|
Important
Search queries for disks based upon name require the
alias search parameter instead of name.

17.4. Actions
17.4.1. Export Template Action
Note
The export storage domain is deprecated. Storage data domains can be unattached from a data center and imported to another data center in the same environment, or in a different environment. Virtual machines, floating virtual disk images, and templates can then be uploaded from the imported storage domain to the attached data center. See the Importing Existing Storage Domains section in the Red Hat Virtualization Administration Guide for information on importing storage domains.
The
templates collection contains an export action.
The export action exports a template to an
Export storage domain. A destination storage domain is specified with a storage_domain reference.
The export action reports a failed action if a virtual machine template of the same name exists in the destination domain. Set the
exclusive parameter to true to change this behavior and overwrite any existing virtual machine template.
Example 17.7. Action to export a template to an export storage domain

|---|---|---|---|
user_name | string | The user principal name (UPN). The UPN is used as a more convenient identifier when adding a new user. |
|
link rel="tags" | relationship | A link to the tags sub-collection for user resources. | |
link rel="roles" | relationship | A link to the roles sub-collection for user resources. | |
name | string | A free-text name for the user. |
|
domain | string | The containing directory service domain. |
|
groups | complex | A list of directory service groups for this user. |
|
22.2. XML representation of a User Resource
Example 22.1. An XML representation of a user resource
GET /ovirt-engine/api/users HTTP/1.1
Accept: application/xml
<user id="225f15cd-e891-434d-8262-a66808fcb9b1"
href="/ovirt-engine/api/users/225f15cd-e891-434d-8262-a66808fcb9b1">
<name>RHEV-M Admin</name>
<actions/>
<link rel="roles"

<domain>domain.example.com</domain>
<logged_in>false</logged_in>
<user_name>rhevmadmin@domain.example.com</user_name>
<groups>
<group>Group Policy Creator Owners@domain.example.com/Users</group>
<group>Domain Admins@domain.example.com/Users</group>
<group>Enterprise Admins@domain.example.com/Users</group>
<group>Schema Admins@domain.example.com/Users</group>
<group>Administrators@domain.example.com/Builtin</group>
</groups>
</user>
22.3. Methods
22.3.1. Adding a User
The API adds an existing directory service user to the Red Hat Virtualization Manager database with a
POST request to the users collection. The client-provided new user representation includes an embedded roles list with at least one initial role to assign to the user. For example, the following request assigns two initial roles to the user joe@domain.example.com:
Example 22.2. Adding a user from directory service and assigning two roles
POST /ovirt-engine/api/users HTTP/1.1
Content-Type: application/xml
Accept: application/xml
<user>
<user_name>joe@domain.example.com</user_name>
<roles>
<role>
<name>RHEVMPowerUser</name>
</role>
<role id="00000000-0000-0000-0001-000000000003"/>
</roles>
</user>
The new user is identified either by Red Hat Virtualization Manager user ID or via the directory service user principal name (UPN). The user ID format reported from the directory service domain might be different to the expected Red Hat Virtualization Manager format, such as in LDIF [5] , the ID has the opposite byte order and is base-64 encoded. Hence it is usually more convenient to refer to the new user by UPN.
Note
The user exists in the directory service domain before it is added to the Red Hat Virtualization Manager database. An API user has the option to query this domain through the
domains collection prior to creation of the user.
Roles are identified either by name or ID. The example above shows both approaches.
22.3.2. Adding Roles to a User
Further roles are attached or detached with
POST or DELETE requests to the roles sub-collection of an individual user. The example below illustrates how the API adds the RHEVMVDIUser role to the role assignments for a particular user.
Note
The embedded user roles list of the
user element is only used for the initial creation. All interactions post-creation with the user's role assignments go through the roles sub-collection.
Example 22.3. Adding roles to a user
POST /ovirt-engine/api/users/225f15cd-e891-434d-8262-a66808fcb9b1/roles HTTP/1.1
Content-Type: application/xml
Accept: application/xml
<role>
<name>RHEVMVDIUser</name>
</role>
Chapter 23. MAC Address Pools
23.1. MAC Address Pool Elements
The
macpools collection provides information about the MAC address pools in a Red Hat Virtualization environment. An API user accesses this information through the rel="macpools" link obtained from the entry point URI. The following table shows specific elements contained in a MAC address pool resource representation.
| Element | Type | Description | Properties |
|---|---|---|---|
name | string | A plain text, human-readable name for the MAC address pool. |
|
description | string | A plain text, human-readable description of the MAC address pool. | |
allow_duplicates | Boolean: true or false | Defines whether duplicate MAC addresses are permitted in the pool. If not specified, allow_duplicates defaults to false. | |
default_pool | Boolean: true or false | Defines whether this is the default pool. If not specified, default_pool defaults to false. |
|
ranges | complex | Defines the range of MAC addresses for the pool. Multiple ranges can be defined within the ranges element. |
|

Chapter 24. Tags
24.1. Tag Elements
The
tags collection provides information about tags in a Red Hat Virtualization environment. An API user accesses this information through the rel="tags" link obtained from the entry point URI.
The following table shows specific elements contained in a tag resource representation.
| Element | Type | Description | Properties |
|---|---|---|---|
host | GUID | A reference to the host which the tag is attached. |
|
user | GUID | A reference to the user which the tag is attached. |
|
vm | GUID | A reference to the VM which the tag is attached. |
|
parent | complex | A reference to the VM which the tag is attached. |
24.2. XML Representation of a Tag Resource
Example 24.1. An XML representation of a tag resource
<tag id="f436ebfc-67f2-41bd-8ec6-902b6f7dcb5e"
href="/ovirt-engine/api/tags/f436ebfc-67f2-41bd-8ec6-902b6f7dcb5e">
<name>Finance</name>
<description>Resources for the Finance department</description>
<parent>
<tag id="-1" href="/ovirt-engine/api/tags/-1"/>
</parent>
</tag>
24.3. Associating Tags
24.3.1. Associating Tags With a Host, User or VM
The collection referenced by
link rel="tags" from a host, user or vms represents the set of tags associated with the entity.
These
tag representations also contain a host id, user id or vm id reference to the entity in question.
Associating a tag with an entity is achieved by
POSTing a tag reference (identifying the tag either by its id or name) to the collection.
Example 24.2. Associating a tag with a virtual machine
POST /ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720/tags HTTP/1.1
Accept: application/xml
Content-Type: application/xml

href="/ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720"/>
</tag>
24.3.2. Removing a Tag
Removing an association is achieved with a
DELETE request to the appropriate element in the collection.
Example 24.3. Removing a tag from a virtual machine
DELETE /ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720/tags/f436ebfc-67f2-41bd-8ec6-902b6f7dcb5e HTTP/1.1 HTTP/1.1 204 No Content
24.3.3. Querying a Collection for Tagged Resources
To query the set of entities associated with a given tag, the
collection/search URI template for the appropriate collection should be used to search for entities matching tag=MyTag.
Example 24.4. Querying a collection for tagged resources
GET /ovirt-engine/api/vms?search=tag%3DFinance HTTP/1.1
Accept: application/xml
HTTP/1.1 200 OK
Content-Type: application/xml
<vms>
<vm id="5114bb3e-a4e6-44b2-b783-b3eea7d84720"
href="/ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720">
...
</vm>
...
</vms>
24.4. Parent Tags
24.4.1. Parent Tags
An API user assigns a
parent element to a tag to create a hierarchical link to a parent tag. The tags are presented as a flat collection, which descends from the root tag, with tag representations containing a link element to a parent tag
Note
The
root tag is a special pseudo-tag assumed as the default parent tag if no parent tag is specified. The root tag cannot be deleted nor assigned a parent tag.
This tag hierarchy is expressed in the following way:
Example 24.5. Tag Hierarchy
<tags>
<tag id="-1" href="/ovirt-engine/api/tags/-1">
<name>root</name>
<description>root</description>
<parent>
<tag id="-1" href="/ovirt-engine/api/tags/-1"/>
</parent>
</tag>
<tag id="f436ebfc-67f2-41bd-8ec6-902b6f7dcb5e"
href="/ovirt-engine/api/tags/f436ebfc-67f2-41bd-8ec6-902b6f7dcb5e">
<name>Finance</name>
<description>Resources for the Finance department</description>
<parent>
<tag id="-1" href="/ovirt-engine/api/tags/-1"/>
</parent>
</tag>
<tag id="ac18dabf-23e5-12be-a383-a38b165ca7bd"
href="/ovirt-engine/api/tags/ac18dabf-23e5-12be-a383-a38b165ca7bd">
<name>Billing</name>
<description>Billing Resources</description>
<parent>
<tag id="f436ebfc-67f2-41bd-8ec6-902b6f7dcb5e"
href="/ovirt-engine/api/tags/f436ebfc-67f2-41bd-8ec6-902b6f7dcb5e"/>
</parent>
</tag>
</tags>
In this XML representation, the tags follow this hierarchy:
root (id: -1)
- Finance (id: f436ebfc-67f2-41bd-8ec6-902b6f7dcb5e)
- Billing (id: ac18dabf-23e5-12be-a383-a38b165ca7bd)
24.4.2. Setting a Parent Tag
POSTing a new tag with a parent element creates an association with a parent tag, using either the id attribute or the name element to reference the parent tag
Example 24.6. Setting an association with a parent tag with the id attribute
POST /ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720/tags HTTP/1.1
Accept: application/xml
Content-Type: application/xml
HTTP/1.1 200 OK
Content-Type: application/xml
<tag>
<name>Billing</name>
<description>Billing Resources</description>
<parent>
<tag id="f436ebfc-67f2-41bd-8ec6-902b6f7dcb5e"/>
</parent>
</tag>
Example 24.7. Setting an association with a parent tag with the name element
POST /ovirt-engine/api/vms/5114bb3e-a4e6-44b2-b783-b3eea7d84720/tags HTTP/1.1
Accept: application/xml
Content-Type: application/xml

<description>Billing Resources</description>
<parent>
<tag>
<name>Finance</name>
</tag>
</parent>
</tag>
24.4.3. Changing a Parent Tag
A tag changes a parent using a
PUT request:
Example 24.8. Changing the parent tag
PUT /ovirt-engine/api/tags/ac18dabf-23e5-12be-a383-a38b165ca7bd HTTP/1.1
Accept: application/xml
Content-Type: application/xml

Chapter 25. Events
25.1. Event Elements
The
rel="events" link obtained from the entry point URI accesses the events collection and lists system events from Red Hat Virtualization Manager.
| Element | Type | Description |
|---|---|---|
description | string | A description of the system event |
code | integer | The integer event code. |
severity | One of normal, warning, error or alert | The level of severity for the event. |
time | xsd:dateTime format: YYYY-MM-DDThh:mm:ss | The timestamp indicating when the event happened. |
correlation_id | string | The identification string for an action that is spread across layers of Red Hat Virtualization. |
user id= | GUID | The identification code for the user who triggered the event. |
origin | string | The source of the event. Standard events are reported by oVirt. |
custom_id | integer | A custom identification number for custom events. Standard events have a custom_id of -1. |
flood_rate | integer | The time, in seconds, during which the same event cannot reoccur in the event list. The default value is 30. |
external_status | complex | The external health status of a host. Contains the state element, which can be one of ok, info, error, warning, or failure. |
25.2. XML Representation of the Events Collection
Example 25.1. An XML representation of the events collection
<events>
<event id="537" href="/ovirt-engine/api/events/537">
<description>User vdcadmin logged in.</description>
<code>30</code>
<severity>normal</severity>
<time>2011-01-12T10:48:27.827+02:00</time>
<user id="9b9002d1-ec33-4083-8a7b-31f6b8931648"
href="/ovirt-engine/api/users/9b9002d1-ec33-4083-8a7b-31f6b8931648"/>
</event>
...
</events>
25.3. XML Representation of a Virtual Machine Creation Event
In addition to
user, an event representation also contains a set of XML element relationships to resources relevant to the event.
Example 25.2. An XML representation of a virtual machine creation event
<event id="635" href="/ovirt-engine/api/events/635">
<description>VM bar was created by rhevadmin.</description>
<code>34</code>
<severity>normal</severity>
<time>2011-07-11T16:32:03.172+02:00</time>
<user id="4621b611-43eb-4d2b-ae5f-1180850268c4"
href="/ovirt-engine/api/users/4621b611-43eb-4d2b-ae5f-1180850268c4"/>
<vm id="9b22d423-e16b-4dd8-9c06-c8e9358fbc66"
href="/ovirt-engine/api/vms/9b22d423-e16b-4dd8-9c06-c8e9358fbc66"/>
<storage_domain id="a8a0e93d-c570-45ab-9cd6-3c68ab31221f"
href="/ovirt-engine/api/storagedomains/a8a0e93d-c570-45ab-9cd6-3c68ab31221f"/>
</event>
This example representation provides XML element relationships to a virtual machine resource and a storage domain resource.
25.4. Methods
25.4.1. Searching Events
The
events collection provides search queries similar to other resource collections. An additional feature when searching the events collection is the ability to search from a certain event. This queries all of events since a specified event.
Querying from an event requires an additional
from parameter added before the search query. This from argument references an event id code.
Example 25.3. Searching from an event
GET /ovirt-engine/api/events;from=1012?search=type%3D30 HTTP/1.1 Accept: application/xml
This displays all events with
type set to 30 since id="1012"
HTTP/1.1 200 OK
Content-Type: application/xml
<events>
<event id="1018" href="/ovirt-engine/api/events/1018">
<description>User admin logged in.</description>
<code>30</code>
<severity>normal</severity>
<time>2011-07-11T14:03:22.485+10:00</time>
<user id="80b71bae-98a1-11e0-8f20-525400866c73"
href="/ovirt-engine/api/users/80b71bae-98a1-11e0-8f20-525400866c73"/>
</event>
<event id="1016" href="/ovirt-engine/api/events/1016">
<description>User admin logged in.</description>
<code>30</code>
<severity>normal</severity>
<time>2011-07-11T14:03:07.236+10:00</time>
<user id="80b71bae-98a1-11e0-8f20-525400866c73"
href="/ovirt-engine/api/users/80b71bae-98a1-11e0-8f20-525400866c73"/>
</event>
<event id="1014" href="/ovirt-engine/api/events/1014">
<description>User admin logged in.</description>
<code>30</code>
<severity>normal</severity>
<time>2011-07-11T14:02:16.009+10:00</time>
<user id="80b71bae-98a1-11e0-8f20-525400866c73"
href="/ovirt-engine/api/users/80b71bae-98a1-11e0-8f20-525400866c73"/>
</event>
</events>
Example 25.4. Searching using a specific event severity
GET /ovirt-engine/api/events?search=severity>normal HTTP/1.1 Accept: application/xml
This displays all events with severity higher than
normal. Severity levels include normal, warning, error and alert.
HTTP/1.1 200 OK
Content-Type: application/xml
<events>
<event id="2823" href="/ovirt-engine/api/events/2823">
<description>Host Host-05 has time-drift of 36002 seconds while maximum configured value is 300 seconds.</description>
<code>604</code>
<severity>warning</severity>
<time>2015-07-11T14:03:22.485+10:00</time>
<host href= "/ovirt-engine/api/hosts/44e52bb2-27d6-4d35-8038-0c4b4db89789" id="44e52bb2-27d6-4d35-8038-0c4b4db89789"/>
<cluster href= "/ovirt-engine/api/clusters/00000001-0001-0001-0001-00000000021b" id="00000001-0001-0001-0001-00000000021b"/>
<origin>oVirt</origin>
<custom_id>-1</custom_id>
<flood_rate>30</flood_rate>
</event>
...
</events>
25.4.2. Paginating Events
A virtualization environment generates a large amount of events after a period of time. However, the API only displays a default number of events for one search query. To display more than the default, the API separates results into pages with the
page command in a search query.
The following search query tells the API to paginate results using a
page value in combination with the sortby clause:
sortby time asc page 1
The
sortby clause defines the base element to order of the results and whether the results are ascending or descending. For search queries of events, set the base element to time and the order to ascending (asc) so the API displays all events from the creation of your virtualization environment.
The
page condition defines the page number. One page equals the default number of events to list. Pagination begins at page 1. To view more pages, increase the page value:
sortby time asc page 2
sortby time asc page 3
sortby time asc page 4
Example 25.5. Paginating events
This example paginates
event resources. The URL-encoded request is:
GET /ovirt-engine/api/events?search=sortby%20time%20asc%20page%201 HTTP/1.1 Accept: application/xml
Increase the
page value to view the next page of results.
GET /ovirt-engine/api/events?search=sortby%20time%20asc%20page%202 HTTP/1.1 Accept: application/xml
Use an additional
from argument to set the starting id.
GET /ovirt-engine/api/events?search=sortby%20time%20asc%20page%202&from=30 HTTP/1.1 Accept: application/xml
25.4.3. Adding Events
The API can add custom events with a
POST request to the events collection. A new event requires the description, severity, origin, and custom_id elements. Custom events can also include flood_rate, user id, and the id codes of any resources relevant to the event. host and storage_domain elements can contain the external_status element to set an external health status.
Example 25.6. Adding a custom event to the event list
POST /ovirt-engine/api/events HTTP/1.1
Accept: application/xml
Content-type: application/xml
<event>
<description>The heat of the host is above 30 Oc</description>
<severity>warning</severity>
<origin>HP Openview</origin>
<custom_id>1</custom_id>
<flood_rate>30</flood_rate>
<host id="f59a29cd-587d-48a3-b72a-db537eb21957" >
<external_status>
<state>warning</state>
</external_status>
</host>
</event>25.4.4. Removing Events
Removal of an event from the event list requires a
DELETE request.
Example 25.7. Removing an event
DELETE /ovirt-engine/api/events/1705 HTTP/1.1 HTTP/1.1 204 No Content
Appendix A. API Usage with cURL
A.1. API Usage with cURL
This appendix provides instructions on adapting REST requests for use with cURL. cURL is a command line tool for transferring data across various protocols, including HTTP, and supports multiple platforms such as Linux, Windows, Mac and Solaris. Most Linux distributions include cURL as a package.
A.2. Installing cURL
A Red Hat Enterprise Linux user installs cURL with the following terminal command:
yum install curl
For other platforms, seek installation instructions on the cURL website (http://curl.haxx.se/).
A.3. Using cURL
cURL uses a command line interface to send requests to a HTTP server. Integrating a request requires the following command syntax:
Usage: curl [options] uri
The
uri refers to target HTTP address to send the request. This is a location on your Red Hat Virtualization Manager host within the API entry point path (/ovirt-engine/api).
cURL options
- -X COMMAND, --request COMMAND
- The request command to use. In the context of the REST API, use
GET,POST,PUTorDELETE.Example:-X GET - -H LINE, --header LINE
- HTTP header to include with the request. Use multiple header options if more than one header is required.Example:
-H "Accept: application/xml" -H "Content-Type: application/xml" - -u USERNAME:PASSWORD, --user USERNAME:PASSWORD
- The user name and password of the Red Hat Virtualization user. This attribute acts as a convenient replacement for the
Authorization:header.Example:-u admin@internal:p@55w0rd! - --cacert CERTIFICATE
- The location of the certificate file for SSL communication to the REST API. The certificate file is saved locally on the client machine. Use the
-kattribute to bypass SSL.Example:--cacert ~/Certificates/rhevm.cer - -d BODY, --data BODY
- The body to send for requests. Use with
POST,PUTandDELETErequests. Ensure to specify theContent-Type: application/xmlheader if a body exists in the request.Example:-d "<cdrom><file id='rhel-server-6.0-x86_64-dvd.iso'/></cdrom>"
A.4. Examples
A.4.1. GET Request with cURL
Example A.1. GET request
The following
GET request lists the virtual machines in the vms collection. Note that a GET request does not contain a body.
GET /ovirt-engine/api/vms HTTP/1.1 Accept: application/xml
Adapt the method (
GET), header (Accept: application/xml) and URI (https://[RHEVM-Host]:443/ovirt-engine/api/vms) into the following cURL command:
$ curl -X GET -H "Accept: application/xml" -u [USER:PASS] --cacert [CERT] https://[RHEVM-Host]:443/ovirt-engine/api/vms
An XML representation of the
vms collection displays.
A.4.2. POST Request with cURL
Example A.2. POST request
The following
POST request creates a virtual machine in the vms collection. Note that a POST request requires a body.
POST /ovirt-engine/api/vms HTTP/1.1
Accept: application/xml
Content-type: application/xml
<vm>
<name>vm1</name>
<cluster>
<name>default</name>
</cluster>
<template>
<name>Blank</name>
</template>
<memory>536870912</memory>
<os>
<boot dev="hd"/>
</os>
</vm>
Adapt the method (
POST), headers (Accept: application/xml and Content-type: application/xml), URI (https://[RHEVM-Host]:443/ovirt-engine/api/vms) and request body into the following cURL command:
$ curl -X POST -H "Accept: application/xml" -H "Content-type: application/xml" -u [USER:PASS] --cacert [CERT] -d "<vm><name>vm1</name><cluster><name>default</name></cluster><template><name>Blank</name></template><memory>536870912</memory><os><boot dev='hd'/></os></vm>" https://[RHEVM-Host]:443/ovirt-engine/api/vms
The REST API creates a new virtual machine and displays an XML representation of the resource.
A.4.3. PUT Request with cURL
Example A.3. PUT request
The following
PUT request updates the memory of a virtual machine resource. Note that a PUT request requires a body.
PUT /ovirt-engine/api/vms/082c794b-771f-452f-83c9-b2b5a19c0399 HTTP/1.1
Accept: application/xml
Content-type: application/xml
<vm>
<memory>1073741824</memory>
</vm>
Adapt the method (
PUT), headers (Accept: application/xml and Content-type: application/xml), URI (https://[RHEVM-Host]:443/ovirt-engine/api/vms/082c794b-771f-452f-83c9-b2b5a19c0399) and request body into the following cURL command:
$ curl -X PUT -H "Accept: application/xml" -H "Content-type: application/xml" -u [USER:PASS] --cacert [CERT] -d "<vm><memory>1073741824</memory></vm>" https://[RHEVM-Host]:443//ovirt-engine/api/vms/082c794b-771f-452f-83c9-b2b5a19c039
The REST API updates the virtual machine with a new memory configuration.
A.4.4. DELETE Request with cURL
Example A.4. DELETE request
The following
DELETE request removes a virtual machine resource.
DELETE /ovirt-engine/api/vms/082c794b-771f-452f-83c9-b2b5a19c0399 HTTP/1.1
Adapt the method (
DELETE) and URI (https://[RHEVM-Host]:443/ovirt-engine/api/vms/082c794b-771f-452f-83c9-b2b5a19c0399) into the following cURL command:
$ curl -X DELETE -u [USER:PASS] --cacert [CERT] https://[RHEVM-Host]:443//ovirt-engine/api/vms/082c794b-771f-452f-83c9-b2b5a19c039
The REST API removes the virtual machine. Note the
Accept: application/xml request header is optional due to the empty result of DELETE requests.
A.4.5. DELETE Request Including Body with cURL
Example A.5. DELETE request with body
The following
DELETE request force removes a virtual machine resource as indicated with the optional body.
DELETE /ovirt-engine/api/vms/082c794b-771f-452f-83c9-b2b5a19c0399 HTTP/1.1 Accept: application/xml Content-type: application/xml <action> <force>true</force> </action>
Adapt the method (
DELETE), headers (Accept: application/xml and Content-type: application/xml), URI (https://[RHEVM-Host]:443/ovirt-engine/api/vms/082c794b-771f-452f-83c9-b2b5a19c0399) and request body into the following cURL command:
$ curl -X DELETE -H "Accept: application/xml" -H "Content-type: application/xml" -u [USER:PASS] --cacert [CERT] -d "<action><force>true</force></action>" https://[RHEVM-Host]:443//ovirt-engine/api/vms/082c794b-771f-452f-83c9-b2b5a19c039
The REST API force removes the virtual machine.
Appendix B. Enumerated Value Translation
