6.50.3.2. follow

Indicates which inner links should be followed. The objects referenced by these links will be fetched as part of the current request. See here for details.

6.50.4. move POST

Moves a disk to another storage domain.

For example, to move the disk with identifier 123 to a storage domain with identifier 456 send the following request:

POST /ovirt-engine/api/disks/123/move

With the following request body:

<action>
  <storage_domain id="456"/>
</action>

If the disk profile or the quota used currently by the disk aren’t defined for the new storage domain, then they can be explicitly specified. If they aren’t then the first available disk profile and the default quota are used.

For example, to explicitly use disk profile 987 and quota 753 send a request body like this:

`quota`	Quota	In	Quota for the disk in the new storage domain.
`storage_domain`	StorageDomain	In

6.50.4.1. disk_profile

Disk profile for the disk in the new storage domain.

Disk profiles are defined for storage domains, so the old disk profile will not exist in the new storage domain. If this parameter is not used, the first disk profile from the new storage domain to which the user has permissions will be assigned to the disk.

6.50.4.2. quota

Quota for the disk in the new storage domain.

This optional parameter can be used to specify new quota for the disk, because the current quota may not be defined for the new storage domain. If this parameter is not used and the old quota is not defined for the new storage domain, the default (unlimited) quota will be assigned to the disk.

6.50.5. reduce POST

Reduces the size of the disk image.

Invokes reduce on the logical volume (i.e. this is only applicable for block storage domains). This is applicable for floating disks and disks attached to non-running virtual machines. There is no need to specify the size as the optimal size is calculated automatically.

Table 6.150. Parameters summary
Name	Type	Direction	Summary
`async`	Boolean	In	Indicates if the remove should be performed asynchronously.

6.50.6. refreshlun POST

Refreshes a direct LUN disk with up-to-date information from the storage.

Refreshing a direct LUN disk is useful when:

The LUN was added using the API without the host parameter, and therefore does not contain any information from the storage (see DisksService::add).
New information about the LUN is available on the storage and you want to update the LUN with it.

To refresh direct LUN disk 123 using host 456, send the following request:

POST /ovirt-engine/api/disks/123/refreshlun

With the following request body:

<action>
  <host id='456'/>
</action>

Table 6.151. Parameters summary
Name	Type	Direction	Summary
`host`	Host	In	The host that will be used to refresh the direct LUN disk.

6.50.7. remove DELETE

Removes a disk.

Table 6.152. Parameters summary
Name	Type	Direction	Summary
`async`	Boolean	In	Indicates if the remove should be performed asynchronously.

6.50.8. sparsify POST

Sparsify the disk.

Sparsification frees space in the disk image that is not used by its filesystem. As a result, the image will occupy less space on the storage.

Currently sparsification works only on disks without snapshots. Disks having derived disks are also not allowed.

6.50.9. update PUT

This operation updates the disk with the appropriate parameters. The only field that can be updated is qcow_version.

For example, update disk can be facilitated using the following request:

PUT /ovirt-engine/api/disks/123

With a request body like this:

<disk>
  <qcow_version>qcow2_v3</qcow_version>
</disk>

Since the backend operation is asynchronous the disk element which will be returned to the user might not be synced with the changed properties.

Table 6.153. Parameters summary
Name	Type	Direction	Summary
`disk`	Disk	In/Out	The update to apply to the disk.

Table 6.173. Methods summary
Name	Summary
`add`	Adds a new floating disk.
`list`	Get list of disks.

6.57.1. add POST

Adds a new floating disk.

There are three types of disks that can be added - disk image, direct LUN and Cinder disk.

Adding a new image disk:

When creating a new floating image Disk, the API requires the storage_domain, provisioned_size and format attributes.

Note that block storage domains (i.e., storage domains with the storage type of iSCSI or FCP) don’t support the combination of the raw format with sparse=true, so sparse=false must be stated explicitly.

To create a new floating image disk with specified provisioned_size, format and name on a storage domain with an id 123, send a request as follows:

POST /ovirt-engine/api/disks

With a request body as follows:

<disk>
  <storage_domains>
    <storage_domain id="123"/>
  </storage_domains>
  <name>mydisk</name>
  <provisioned_size>1048576</provisioned_size>
  <format>cow</format>
</disk>

Adding a new direct LUN disk:

When adding a new floating direct LUN via the API, there are two flavors that can be used:

With a host element - in this case, the host is used for sanity checks (e.g., that the LUN is visible) and to retrieve basic information about the LUN (e.g., size and serial).
Without a host element - in this case, the operation is a database-only operation, and the storage is never accessed.

To create a new floating direct LUN disk with a host element with an id 123, specified alias, type and logical_unit with an id 456 (that has the attributes address, port and target), send a request as follows:

POST /ovirt-engine/api/disks

With a request body as follows:

<disk>
  <alias>mylun</alias>
  <lun_storage>
    <host id="123"/>
    <type>iscsi</type>
    <logical_units>
      <logical_unit id="456">
        <address>10.35.10.20</address>
        <port>3260</port>
        <target>iqn.2017-01.com.myhost:444</target>
      </logical_unit>
    </logical_units>
  </lun_storage>
</disk>

To create a new floating direct LUN disk without using a host, remove the host element.

Adding a new Cinder disk:

To create a new floating Cinder disk, send a request as follows:

POST /ovirt-engine/api/disks

With a request body as follows:

<disk>
  <openstack_volume_type>
    <name>myceph</name>
  </openstack_volume_type>
  <storage_domains>
    <storage_domain>
      <name>cinderDomain</name>
    </storage_domain>
  </storage_domains>
  <provisioned_size>1073741824</provisioned_size>
  <interface>virtio</interface>
  <format>raw</format>
</disk>

Adding a floating disks in order to upload disk snapshots:

Since version 4.2 of the engine it is possible to upload disks with snapshots. This request should be used to create the base image of the images chain (The consecutive disk snapshots (images), should be created using disk-attachments element when creating a snapshot).

The disk has to be created with the same disk identifier and image identifier of the uploaded image. I.e. the identifiers should be saved as part of the backup process. The image identifier can be also fetched using the qemu-img info command. For example, if the disk image is stored into a file named b7a4c6c5-443b-47c5-967f-6abc79675e8b/myimage.img:

$ qemu-img info b7a4c6c5-443b-47c5-967f-6abc79675e8b/myimage.img
image: b548366b-fb51-4b41-97be-733c887fe305
file format: qcow2
virtual size: 1.0G (1073741824 bytes)
disk size: 196K
cluster_size: 65536
backing file: ad58716a-1fe9-481f-815e-664de1df04eb
backing file format: raw

To create a disk with with the disk identifier and image identifier obtained with the qemu-img info command shown above, send a request like this:

POST /ovirt-engine/api/disks

With a request body as follows:

<disk id="b7a4c6c5-443b-47c5-967f-6abc79675e8b">
  <image_id>b548366b-fb51-4b41-97be-733c887fe305</image_id>
  <storage_domains>
    <storage_domain id="123"/>
  </storage_domains>
  <name>mydisk</name>
  <provisioned_size>1048576</provisioned_size>
  <format>cow</format>
</disk>

`add`	Adds an external event to the internal audit log.
`list`	Get list of events.
`undelete`

6.67.1. add POST

Adds an external event to the internal audit log.

This is intended for integration with external systems that detect or produce events relevant for the administrator of the system. For example, an external monitoring tool may be able to detect that a file system is full inside the guest operating system of a virtual machine. This event can be added to the internal audit log sending a request like this:

POST /ovirt-engine/api/events
<event>
  <description>File system /home is full</description>
  <severity>alert</severity>
  <origin>mymonitor</origin>
  <custom_id>1467879754</custom_id>
</event>

Events can also be linked to specific objects. For example, the above event could be linked to the specific virtual machine where it happened, using the vm link:

POST /ovirt-engine/api/events
<event>
  <description>File system /home is full</description>
  <severity>alert</severity>
  <origin>mymonitor</origin>
  <custom_id>1467879754</custom_id>
  <vm id="aae98225-5b73-490d-a252-899209af17e9"/>
</event>

Note

When using links, like the vm in the previous example, only the id attribute is accepted. The name attribute, if provided, is simply ignored.

The following events occur:

id="1" - The API logs in the admin user account.
id="2" - The API logs out of the admin user account.

The order of the returned list of events is always garanteed. If the sortby clause is included in the search parameter, then the events will be ordered according to that clause. If the sortby clause isn’t included, then the events will be sorted by the numeric value of the id attribute, starting with the highest value. This, combined with the max parameter, simplifies obtaining the most recent event:

GET /ovirt-engine/api/events?max=1

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

Below example paginates event resources. The URL-encoded request is:

GET /ovirt-engine/api/events?search=sortby%20time%20asc%20page%201

Increase the page value to view the next page of results.

GET /ovirt-engine/api/events?search=sortby%20time%20asc%20page%202

Returns the list of ISO images and virtual floppy disks available in the storage domain. The order of the returned list is not guaranteed.

If the refresh parameter is false, the returned list may not reflect recent changes to the storage domain; for example, it may not contain a new ISO file that was recently added. This is because the server caches the list of files to improve performance. To get the very latest results, set the refresh parameter to true.

The default value of the refresh parameter is true, but it can be changed using the configuration value ForceRefreshDomainFilesByDefault:

# engine-config -s ForceRefreshDomainFilesByDefault=false

Important

Setting the value of the refresh parameter to true has an impact on the performance of the server. Use it only if necessary.

Sets the maximum number of bricks to return. If not specified all the bricks are returned.

6.92.4. migrate POST

Start migration of data prior to removing bricks.

Removing bricks is a two-step process, where the data on bricks to be removed, is first migrated to remaining bricks. Once migration is completed the removal of bricks is confirmed via the API remove. If at any point, the action needs to be cancelled stopmigrate has to be called.

For instance, to delete a brick from a gluster volume with id 123, send a request:

POST /ovirt-engine/api/clusters/567/glustervolumes/123/glusterbricks/migrate

With a request body like this:

<action>
  <bricks>
    <brick>
      <name>host1:/rhgs/brick1</name>
    </brick>
  </bricks>
</action>

The migration process can be tracked from the job id returned from the API using job and steps in job using step

`async`	Boolean	In	Indicates if the migration should be performed asynchronously.
`bricks`	GlusterBrick[]	In	List of bricks for which data migration needs to be started.

6.92.5. remove DELETE

Removes bricks from gluster volume.

The recommended way to remove bricks without data loss is to first migrate the data using stopmigrate and then removing them. If migrate was not called on bricks prior to remove, the bricks are removed without data migration which may lead to data loss.

For example, to delete the bricks from gluster volume 123, send a request like this:

DELETE /ovirt-engine/api/clusters/567/glustervolumes/123/glusterbricks

6.109. Hosts

A service that manages hosts.

Table 6.333. Methods summary
Name	Summary
`add`	Creates a new host.
`list`	Get a list of all available hosts.

6.109.1. add POST

Creates a new host.

The host is created based on the attributes of the host parameter. The name, address and root_password properties are required.

For example, to add a host send the following request:

POST /ovirt-engine/api/hosts

With the following request body:

<host>
  <name>myhost</name>
  <address>myhost.example.com</address>
  <root_password>myrootpassword</root_password>
</host>

Note

The root_password element is only included in the client-provided initial representation and is not exposed in the representations returned from subsequent requests.

Important

Since version 4.1.2 of the engine when a host is newly added we override the host firewall definitions by default.

To add a hosted engine host, use the optional deploy_hosted_engine parameter:

POST /ovirt-engine/api/hosts?deploy_hosted_engine=true

If the cluster has a default external network provider which is supported for automatic deployment, the external network provider is deployed when adding the host. Only external network providers for OVN are supported for the automatic deployment. To deploy an external network provider that differs to what is defined in the clusters, overwrite the external network provider when adding hosts by sending a request like this:

POST /ovirt-engine/api/hosts

With a request body that contains a reference to the desired provider in the external_network_provider_configuration:

<host>
  <name>myhost</name>
  <address>myhost.example.com</address>
  <root_password>123456</root_password>
  <external_network_provider_configurations>
    <external_network_provider_configuration>
      <external_network_provider name="ovirt-provider-ovn"/>
    </external_network_provider_configuration>
  </external_network_provider_configurations>
</host>

6.113. ImageTransfer

This service provides a mechanism to control an image transfer. The client will have to create a transfer by using add of the Section 6.114, “ImageTransfers” service, stating the image to transfer data to/from.

After doing that, the transfer is managed by this service.

Using oVirt’s Python’s SDK:

Uploading a disk with id 123 (on a random host in the data center):

transfers_service = system_service.image_transfers_service()
transfer = transfers_service.add(
   types.ImageTransfer(
      disk=types.Disk(
         id='123'
      )
   )
)

Uploading a disk with id 123 on host id 456:

transfers_service = system_service.image_transfers_service()
transfer = transfers_service.add(
   types.ImageTransfer(
      disk=types.Disk(
         id='123'
      ),
      host=types.Host(
         id='456'
     )
   )
)

If the user wishes to download a disk rather than upload, he/she should specify download as the direction attribute of the transfer. This will grant a read permission from the image, instead of a write permission.

E.g:

transfers_service = system_service.image_transfers_service()
transfer = transfers_service.add(
   types.ImageTransfer(
      disk=types.Disk(
         id='123'
      ),
      direction=types.ImageTransferDirection.DOWNLOAD
   )
)

Transfers have phases, which govern the flow of the upload/download. A client implementing such a flow should poll/check the transfer’s phase and act accordingly. All the possible phases can be found in ImageTransferPhase.

After adding a new transfer, its phase will be initializing. The client will have to poll on the transfer’s phase until it changes. When the phase becomes transferring, the session is ready to start the transfer.

For example:

transfer_service = transfers_service.image_transfer_service(transfer.id)
while transfer.phase == types.ImageTransferPhase.INITIALIZING:
   time.sleep(3)
   transfer = transfer_service.get()

At that stage, if the transfer’s phase is paused_system, then the session was not successfully established. One possible reason for that is that the ovirt-imageio-daemon is not running in the host that was selected for transfer. The transfer can be resumed by calling resume of the service that manages it.

If the session was successfully established - the returned transfer entity will contain the proxy_url and signed_ticket attributes, which the client needs to use in order to transfer the required data. The client can choose whatever technique and tool for sending the HTTPS request with the image’s data.

proxy_url is the address of a proxy server to the image, to do I/O to.
signed_ticket is the content that needs to be added to the Authentication header in the HTTPS request, in order to perform a trusted communication.

For example, Python’s HTTPSConnection can be used in order to perform a transfer, so an transfer_headers dict is set for the upcoming transfer:

transfer_headers = {
   'Authorization' :  transfer.signed_ticket,
}

Using Python’s HTTPSConnection, a new connection is established:

# Extract the URI, port, and path from the transfer's proxy_url.
url = urlparse.urlparse(transfer.proxy_url)

# Create a new instance of the connection.
proxy_connection = HTTPSConnection(
   url.hostname,
   url.port,
   context=ssl.SSLContext(ssl.PROTOCOL_SSLv23)
)

For upload, the specific content range being sent must be noted in the Content-Range HTTPS header. This can be used in order to split the transfer into several requests for a more flexible process.

For doing that, the client will have to repeatedly extend the transfer session to keep the channel open. Otherwise, the session will terminate and the transfer will get into paused_system phase, and HTTPS requests to the server will be rejected.

E.g., the client can iterate on chunks of the file, and send them to the proxy server while asking the service to extend the session:

path = "/path/to/image"
MB_per_request = 32
with open(path, "rb") as disk:
   size = os.path.getsize(path)
   chunk_size = 1024*1024*MB_per_request
   pos = 0
   while (pos < size):
      transfer_service.extend()
      transfer_headers['Content-Range'] = "bytes %d-%d/%d" % (pos, min(pos + chunk_size, size)-1, size)
      proxy_connection.request(
         'PUT',
         url.path,
         disk.read(chunk_size),
         headers=transfer_headers
      )
      r = proxy_connection.getresponse()
      print r.status, r.reason, "Completed", "{:.0%}".format(pos/ float(size))
      pos += chunk_size

Similarly, for a download transfer, a Range header must be sent, making the download process more easily managed by downloading the disk in chunks.

E.g., the client will again iterate on chunks of the disk image, but this time he/she will download it to a local file, rather than uploading its own file to the image:

output_file = "/home/user/downloaded_image"
MiB_per_request = 32
chunk_size = 1024*1024*MiB_per_request
total = disk_size

with open(output_file, "wb") as disk:
   pos = 0
   while pos < total:
      transfer_service.extend()
      transfer_headers['Range'] = "bytes=%d-%d" %  (pos, min(total, pos + chunk_size) - 1)
      proxy_connection.request('GET', proxy_url.path, headers=transfer_headers)
      r = proxy_connection.getresponse()
      disk.write(r.read())
      print "Completed", "{:.0%}".format(pos/ float(total))
      pos += chunk_size

When finishing the transfer, the user should call finalize. This will make the final adjustments and verifications for finishing the transfer process.

For example:

transfer_service.finalize()

In case of an error, the transfer’s phase will be changed to finished_failure, and the disk’s status will be changed to Illegal. Otherwise it will be changed to finished_success, and the disk will be ready to be used. In both cases, the transfer entity will be removed shortly after.

Using HTTP and cURL calls:

For upload, create a new disk first:
- Specify 'initial_size' and 'provisioned_size' in bytes.
- 'initial_size' must be bigger or the same as the size of the uploaded data.

POST /ovirt-engine/api/disks

With a request body as follows:

<disk>
  <storage_domains>
    <storage_domain id="123"/>
  </storage_domains>
  <alias>mydisk</alias>
  <initial_size>1073741824</initial_size>
  <provisioned_size>1073741824</provisioned_size>
  <format>raw</format>
</disk>

Create a new image transfer for downloading/uploading a disk with id 456:

POST /ovirt-engine/api/imagetransfers

With a request body as follows:

<image_transfer>
  <disk id="456"/>
  <direction>upload|download</direction>
</image_transfer>

Will respond:

<image_transfer id="123">
  <direction>download|upload</direction>
  <phase>initializing|transferring</phase>
  <proxy_url>https://proxy_fqdn:54323/images/41c732d4-2210-4e7b-9e5c-4e2805baadbb</proxy_url>
  <transfer_url>https://daemon_fqdn:54322/images/41c732d4-2210-4e7b-9e5c-4e2805baadbb</transfer_url>
  ...
</image_transfer>

Note: If the phase is 'initializing', poll the image_transfer till its phase changes to 'transferring'.

Use the 'transfer_url' or 'proxy_url' to invoke a curl command:
use 'transfer_url' for transferring directly from/to ovirt-imageio-daemon, or, use 'proxy_url' for transferring from/to ovirt-imageio-proxy. Note: using the proxy would mitigate scenarios where there’s no direct connectivity to the daemon machine, e.g. vdsm machines are on a different network than the engine.

— Download:

$ curl --cacert /etc/pki/ovirt-engine/ca.pem https://daemon_fqdn:54322/images/41c732d4-2210-4e7b-9e5c-4e2805baadbb -o <output_file>

— Upload:

$ curl --cacert /etc/pki/ovirt-engine/ca.pem --upload-file <file_to_upload> -X PUT https://daemon_fqdn:54322/images/41c732d4-2210-4e7b-9e5c-4e2805baadbb

For example, to remove the association of network 456 to data center 123 send a request like this:

DELETE /ovirt-engine/api/datacenters/123/networks/456

Note

To remove an external logical network, the network has to be removed directly from its provider by OpenStack Networking API. The entity representing the external network inside Red Hat Virtualization is removed automatically, if auto_sync is enabled for the provider, otherwise the entity has to be removed using this method.

6.139. NetworkFilters

Represents a readonly network filters sub-collection.

The network filter enables to filter packets send to/from the VM’s nic according to defined rules. For more information please refer to NetworkFilter service documentation

Network filters are supported in different versions, starting from version 3.0.

A network filter is defined for each vnic profile.

A vnic profile is defined for a specific network.

A network can be assigned to several different clusters. In the future, each network will be defined in cluster level.

Currently, each network is being defined at data center level. Potential network filters for each network are determined by the network’s data center compatibility version V. V must be >= the network filter version in order to configure this network filter for a specific network. Please note, that if a network is assigned to cluster with a version supporting a network filter, the filter may not be available due to the data center version being smaller then the network filter’s version.

Example of listing all of the supported network filters for a specific cluster:

GET http://localhost:8080/ovirt-engine/api/clusters/{cluster:id}/networkfilters

Output:

Table 6.564. Methods summary
Name	Summary
`add`	Creates a virtual machine snapshot.
`list`	Returns the list of snapshots of the storage domain or virtual machine.

6.187.1. add POST

Creates a virtual machine snapshot.

For example, to create a new snapshot for virtual machine 123 send a request like this:

POST /ovirt-engine/api/vms/123/snapshots

With a request body like this:

<snapshot>
  <description>My snapshot</description>
</snapshot>

For including only a sub-set of disks in the snapshots, add disk_attachments element to the request body. Note that disks which are not specified in disk_attachments element will not be a part of the snapshot. If an empty disk_attachments element is passed, the snapshot will include only the virtual machine configuration. If no disk_attachments element is passed, then all the disks will be included in the snapshot.

For each disk, image_id element can be specified for setting the new active image id. This is used in order to restore a chain of images from backup. I.e. when restoring a disk with snapshots, the relevant image_id should be specified for each snapshot (so the identifiers of the disk snapshots are identical to the backup).

<snapshot>
  <description>My snapshot</description>
  <disk_attachments>
    <disk_attachment>
      <disk id="123">
        <image_id>456</image_id>
      </disk>
    </disk_attachment>
  </disk_attachments>
</snapshot>

Important

When a snapshot is created the default value for the persist_memorystate attribute is true. That means that the content of the memory of the virtual machine will be included in the snapshot, and it also means that the virtual machine will be paused for a longer time. That can negatively affect applications that are very sensitive to timing (NTP servers, for example). In those cases make sure that you set the attribute to false:

<snapshot>
  <description>My snapshot</description>
  <persist_memorystate>false</persist_memorystate>
</snapshot>

Without any special parameters, the storage domain is detached from the system and removed from the database. The storage domain can then be imported to the same or to a different setup, with all the data on it. If the storage is not accessible the operation will fail.

If the destroy parameter is true then the operation will always succeed, even if the storage is not accessible, the failure is just ignored and the storage domain is removed from the database anyway.

If the format parameter is true then the actual storage is formatted, and the metadata is removed from the LUN or directory, so it can no longer be imported to the same or to a different setup.

Table 6.591. Parameters summary
Name	Type	Direction	Summary
`async`	Boolean	In	Indicates if the remove should be performed asynchronously.
`destroy`	Boolean	In	Indicates if the operation should succeed, and the storage domain removed from the database, even if the storage is not accessible.

`host`	String	In	Indicates which host should be used to remove the storage domain.

6.195.5.1. destroy

Indicates if the operation should succeed, and the storage domain removed from the database, even if the storage is not accessible.

DELETE /ovirt-engine/api/storagedomains/123?destroy=true

This parameter is optional, and the default value is false. When the value of destroy is true the host parameter will be ignored.

6.195.5.2. host

Indicates which host should be used to remove the storage domain.

This parameter is mandatory, except if the destroy parameter is included and its value is true, in that case the host parameter will be ignored.

The value should contain the name or the identifier of the host. For example, to use the host named myhost to remove the storage domain with identifier 123 send a request like this:

DELETE /ovirt-engine/api/storagedomains/123?host=myhost

6.195.6. update PUT

Updates a storage domain.

Not all of the StorageDomain's attributes are updatable after creation. Those that can be updated are: name, description, comment, warning_low_space_indicator, critical_space_action_blocker and wipe_after_delete. (Note that changing the wipe_after_delete attribute will not change the wipe after delete property of disks that already exist).

To update the name and wipe_after_delete attributes of a storage domain with an identifier 123, send a request as follows:

PUT /ovirt-engine/api/storagedomains/123

With a request body as follows:

<storage_domain>

6.232. Templates

This service manages the virtual machine templates available in the system.

Table 6.705. Methods summary
Name	Summary
`add`	Creates a new template.
`list`	Returns the list of virtual machine templates.

6.232.1. add POST

Creates a new template.

This requires the name and vm elements. To identify the virtual machine use the vm.id or vm.name attributes. For example, to create a template from a virtual machine with the identifier 123 send a request like this:

POST /ovirt-engine/api/templates

With a request body like this:

<template>
  <name>mytemplate</name>
  <vm id="123"/>
</template>

The disks of the template can be customized, making some of their characteristics different from the disks of the original virtual machine. To do so use the vm.disk_attachments attribute, specifying the identifier of the disk of the original virtual machine and the characteristics that you want to change. For example, if the original virtual machine has a disk with the identifier 456, and, for that disk, you want to change the name to mydisk the format to Copy On Write and make it sparse, send a request body like this:

<template>
  <name>mytemplate</name>
  <vm id="123">
    <disk_attachments>
      <disk_attachment>
        <disk id="456">
          <name>mydisk</name>
          <format>cow</format>
          <sparse>true</sparse>
        </disk>
      </disk_attachment>
    </disk_attachments>
  </vm>
</template>

The template can be created as a sub-version of an existing template. This requires the name and vm attributes for the new template, and the base_template and version_name attributes for the new template version. The base_template and version_name attributes must be specified within a version section enclosed in the template section. Identify the virtual machine with the id or name attributes.

<template>
  <name>mytemplate</name>
  <vm id="123"/>
  <version>
    <base_template id="456"/>
    <version_name>mytemplate_001</version_name>
  </version>
</template>

The destination storage domain of the template can be customized, in one of two ways:

Globally, at the request level. The request must list the desired disk attachments to be created on the storage domain. If the disk attachments are not listed, the global storage domain parameter will be ignored.

<template>
  <name>mytemplate</name>
  <storage_domain id="123"/>
  <vm id="456">
    <disk_attachments>
      <disk_attachment>
        <disk id="789">
          <format>cow</format>
          <sparse>true</sparse>
        </disk>
      </disk_attachment>
    </disk_attachments>
  </vm>
</template>

Per each disk attachment. Specify the desired storage domain for each disk attachment. Specifying the global storage definition will override the storage domain per disk attachment specification.

<template>
  <name>mytemplate</name>
  <vm id="123">
    <disk_attachments>
      <disk_attachment>
        <disk id="456">
          <format>cow</format>
          <sparse>true</sparse>
          <storage_domains>
             <storage_domain id="789"/>
          </storage_domains>
        </disk>
      </disk_attachment>
    </disk_attachments>
  </vm>
</template>

Table 6.706. Parameters summary
Name	Type	Direction	Summary
`clone_permissions`	Boolean	In	Specifies if the permissions of the virtual machine should be copied to the template.
`seal`	Boolean	In	Seals the template.
`template`	Template	In/Out	The information about the template or template version.

6.232.1.1. clone_permissions

Specifies if the permissions of the virtual machine should be copied to the template.

If this optional parameter is provided, and its value is true, then the permissions of the virtual machine (only the direct ones, not the inherited ones) will be copied to the created template. For example, to create a template from the myvm virtual machine copying its permissions, send a request like this:

POST /ovirt-engine/api/templates?clone_permissions=true

With a request body like this:

<template>
  <name>mytemplate<name>
  <vm>
    <name>myvm<name>
  </vm>
</template>

6.232.1.2. seal

Seals the template.

If this optional parameter is provided and its value is true, then the template is sealed after creation.

Sealing erases all host-specific configuration from the filesystem: SSH keys, UDEV rules, MAC addresses, system ID, hostname, and so on, thus making it easier to use the template to create multiple virtual machines without manual intervention.

Currently, sealing is supported only for Linux operating systems.

6.232.2. list GET

Returns the list of virtual machine templates.

For example:

GET /ovirt-engine/api/templates

6.239.7.1. all_content

Indicates if all of the attributes of the virtual machine should be included in the response.

By default the following attributes are excluded:

console
initialization.configuration.data - The OVF document describing the virtual machine.
rng_source
soundcard
virtio_scsi

For example, to retrieve the complete representation of the virtual machine '123':

GET /ovirt-engine/api/vms/123?all_content=true

Note

These attributes are not included by default as they reduce performance. These attributes are seldom used and require additional queries to the database. Only use this parameter when required as it will reduce performance.

6.239.7.2. follow

Indicates which inner links should be followed. The objects referenced by these links will be fetched as part of the current request. See here for details.

6.239.7.3. next_run

Indicates if the returned result describes the virtual machine as it is currently running or if describes the virtual machine with the modifications that have already been performed but that will only come into effect when the virtual machine is restarted. By default the value is false.

If the parameter is included in the request, but without a value, it is assumed that the value is true. The the following request:

GET /vms/{vm:id};next_run

Is equivalent to using the value true:

GET /vms/{vm:id};next_run=true

6.239.8. logon POST

Initiates the automatic user logon to access a virtual machine from an external console.

This action requires the ovirt-guest-agent-gdm-plugin and the ovirt-guest-agent-pam-module packages to be installed and the ovirt-guest-agent service to be running on the virtual machine.

It allows to change or eject the disk by changing the value of the file attribute. For example, to insert or change the disk send a request like this:

PUT /ovirt-engine/api/vms/123/cdroms/00000000-0000-0000-0000-000000000000

The body should contain the new value for the file attribute:

<cdrom>
  <file id="mycd.iso"/>
</cdrom>

The value of the id attribute, mycd.iso in this example, should correspond to a file available in an attached ISO storage domain.

To eject the disk use a file with an empty id:

<cdrom>
  <file id=""/>
</cdrom>

By default the above operations change permanently the disk that will be visible to the virtual machine after the next boot, but they don’t have any effect on the currently running virtual machine. If you want to change the disk that is visible to the current running virtual machine, add the current=true parameter. For example, to eject the current disk send a request like this:

PUT /ovirt-engine/api/vms/123/cdroms/00000000-0000-0000-0000-000000000000?current=true

# Find the virtual machine:
vm = vms_service.list(search='name=myvm')[0]

# Locate the service that manages the virtual machine, as that is where
# the locators are defined:
vm_service = vms_service.vm_service(vm.id)

# Find the graphic console of the virtual machine:
graphics_consoles_service = vm_service.graphics_consoles_service()
graphics_console = graphics_consoles_service.list()[0]

# Generate the remote viewer connection file:
console_service = graphics_consoles_service.console_service(graphics_console.id)
remote_viewer_connection_file = console_service.remote_viewer_connection_file()

# Write the content to file "/tmp/remote_viewer_connection_file.vv"
path = "/tmp/remote_viewer_connection_file.vv"
with open(path, "w") as f:
    f.write(remote_viewer_connection_file)

When you create the remote viewer connection file, then you can connect to virtual machine graphic console, as follows:

url="https://engine.example.com/ovirt-engine/api"
user="admin@internal"
password="..."
curl \
--verbose \
--cacert /etc/pki/ovirt-engine/ca.pem \
--user "${user}:${password}" \
--request POST \
--header "Version: 4" \
--header "Content-Type: application/xml" \
--header "Accept: application/xml" \
--data '
<vm>
  <name>myvm</name>
  <template>
    <name>Blank</name>
  </template>
  <cluster>
    <name>mycluster</name>
  </cluster>
</vm>
' \
"${url}/vms"

From a snapshot. In this case the identifier of the snapshot has to be provided. For example, using a plain shel script and XML:

#!/bin/sh -ex

url="https://engine.example.com/ovirt-engine/api"
user="admin@internal"
password="..."
curl \
--verbose \
--cacert /etc/pki/ovirt-engine/ca.pem \
--user "${user}:${password}" \
--request POST \
--header "Content-Type: application/xml" \
--header "Accept: application/xml" \
--data '
<vm>
  <name>myvm</name>
  <snapshots>
    <snapshot id="266742a5-6a65-483c-816d-d2ce49746680"/>
  </snapshots>
  <cluster>
    <name>mycluster</name>
  </cluster>
</vm>
' \
"${url}/vms"

When creating a virtual machine from a template or from a snapshot it is usually useful to explicitly indicate in what storage domain to create the disks for the virtual machine. If the virtual machine is created from a template then this is achieved passing a set of disk_attachment elements that indicate the mapping:

<vm>
  ...
  <disk_attachments>
    <disk_attachment>
      <disk id="8d4bd566-6c86-4592-a4a7-912dbf93c298">
        <storage_domains>
          <storage_domain id="9cb6cb0a-cf1d-41c2-92ca-5a6d665649c9"/>
        </storage_domains>
      </disk>
    <disk_attachment>
  </disk_attachments>
</vm>

When the virtual machine is created from a snapshot this set of disks is slightly different, it uses the image_id attribute instead of id.

<vm>
  ...
  <disk_attachments>
    <disk_attachment>
      <disk>
        <image_id>8d4bd566-6c86-4592-a4a7-912dbf93c298</image_id>
        <storage_domains>
          <storage_domain id="9cb6cb0a-cf1d-41c2-92ca-5a6d665649c9"/>
        </storage_domains>
      </disk>
    <disk_attachment>
  </disk_attachments>
</vm>

It is possible to specify additional virtual machine parameters in the XML description, e.g. a virtual machine of desktop type, with 2 GiB of RAM and additional description can be added sending a request body like the following:

<vm>
  <name>myvm</name>
  <description>My Desktop Virtual Machine</description>
  <type>desktop</type>
  <memory>2147483648</memory>
  ...
</vm>

A bootable CDROM device can be set like this:

<vm>
  ...
  <os>
    <boot dev="cdrom"/>
  </os>
</vm>

In order to boot from CDROM, you first need to insert a disk, as described in the CDROM service. Then booting from that CDROM can be specified using the os.boot.devices attribute:

<vm>
  ...
  <os>
    <boot>
      <devices>
        <device>cdrom</device>
      </devices>
    </boot>
  </os>
</vm>

In all cases the name or identifier of the cluster where the virtual machine will be created is mandatory.

Table 6.825. Parameters summary
Name	Type	Direction	Summary
`clone`	Boolean	In	Specifies if the virtual machine should be independent of the template.
`clone_permissions`	Boolean	In	Specifies if the permissions of the template should be copied to the virtual machine.
`vm`	Vm	In/Out

6.262.1.1. clone

Specifies if the virtual machine should be independent of the template.

When a virtual machine is created from a template by default the disks of the virtual machine depend on the disks of the template, they are using the copy on write mechanism so that only the differences from the template take up real storage space. If this parameter is specified and the value is true then the disks of the created virtual machine will be cloned, and independent of the template. For example, to create an independent virtual machine, send a request like this:

POST /ovirt-engine/vms?clone=true

With a request body like this:

<vm>
  <name>myvm<name>
  <template>
    <name>mytemplate<name>
  </template>
  <cluster>
    <name>mycluster<name>
  </cluster>
</vm>

Note

When this parameter is true the permissions of the template will also be copied, as when using clone_permissions=true.

6.262.1.2. clone_permissions

Specifies if the permissions of the template should be copied to the virtual machine.

If this optional parameter is provided, and its values is true then the permissions of the template (only the direct ones, not the inherited ones) will be copied to the created virtual machine. For example, to create a virtual machine from the mytemplate template copying its permissions, send a request like this:

POST /ovirt-engine/api/vms?clone_permissions=true

With a request body like this:

<vm>
  <name>myvm<name>
  <template>
    <name>mytemplate<name>
  </template>
  <cluster>
    <name>mycluster<name>
  </cluster>
</vm>

6.262.2. list GET

Returns the list of virtual machines of the system.

The order of the returned list of virtual machines is guaranteed only if the sortby clause is included in the search parameter.

Table 6.826. Parameters summary
Name	Type	Direction	Summary
`all_content`	Boolean	In	Indicates if all the attributes of the virtual machines should be included in the response.
`case_sensitive`	Boolean	In	Indicates if the search performed using the `search` parameter should be performed taking case into account.
`filter`	Boolean	In	Indicates if the results should be filtered according to the permissions of the user.
`follow`	String	In	Indicates which inner links should be followed.
`max`	Integer	In	The maximum number of results to return.
`search`	String	In	A query string used to restrict the returned virtual machines.
`vms`	Vm[]	Out

6.262.2.1. all_content

Indicates if all the attributes of the virtual machines should be included in the response.

By default the following attributes are excluded:

console
initialization.configuration.data - The OVF document describing the virtual machine.
rng_source
soundcard
virtio_scsi

For example, to retrieve the complete representation of the virtual machines send a request like this:

GET /ovirt-engine/api/vms?all_content=true

Note

The reason for not including these attributes is performance: they are seldom used and they require additional queries to the database. So try to use the this parameter only when it is really needed.

6.262.2.2. case_sensitive

Indicates if the search performed using the search parameter should be performed taking case into account. The default value is true, which means that case is taken into account. If you want to search ignoring case set it to false.

6.262.2.3. follow

Indicates which inner links should be followed. The objects referenced by these links will be fetched as part of the current request. See here for details.

6.263. VnicProfile

Table 6.829. Parameters summary
Name	Type	Direction	Summary
`async`	Boolean	In	Indicates if the remove should be performed asynchronously.

6.263.3. update PUT

Updates details of a vNIC profile.

Table 6.830. Parameters summary

6.264. VnicProfiles

This service manages the collection of all vNIC profiles.

Table 6.831. Methods summary
Name	Summary
`add`	Add a vNIC profile.
`list`	List all vNIC profiles.

6.264.1. add POST

Add a vNIC profile.

For example to add vNIC profile 123 to network 456 send a request to:

POST /ovirt-engine/api/networks/456/vnicprofiles

With the following body:

<vnic_profile id="123">
  <name>new_vNIC_name</name>
  <pass_through>
    <mode>disabled</mode>
  </pass_through>
  <port_mirroring>false</port_mirroring>
</vnic_profile>

Please note that there is a default network filter to each VNIC profile. For more details of how the default network filter is calculated please refer to the documentation in NetworkFilters.

Note

The automatically created vNIC profile for the external network will be without network filter.

The output of creating a new VNIC profile depends in the body arguments that were given. In case no network filter was given, the default network filter will be configured. For example:

<vnic_profile href="/ovirt-engine/api/vnicprofiles/123" id="123">
  <name>new_vNIC_name</name>
  <link href="/ovirt-engine/api/vnicprofiles/123/permissions" rel="permissions"/>
  <pass_through>
    <mode>disabled</mode>
  </pass_through>
  <port_mirroring>false</port_mirroring>
  <network href="/ovirt-engine/api/networks/456" id="456"/>
  <network_filter href="/ovirt-engine/api/networkfilters/789" id="789"/>
</vnic_profile>

In case an empty network filter was given, no network filter will be configured for the specific VNIC profile regardless of the VNIC profile’s default network filter. For example:

<vnic_profile>
  <name>no_network_filter</name>
  <network_filter/>
</vnic_profile>

In case that a specific valid network filter id was given, the VNIC profile will be configured with the given network filter regardless of the VNIC profiles’s default network filter. For example:

<vnic_profile>
  <name>user_choice_network_filter</name>
  <network_filter id= "0000001b-001b-001b-001b-0000000001d5"/>
</vnic_profile>
