2.9. External Providers

2.9.1. Introduction to External Providers in Red Hat Virtualization

In addition to resources managed by the Red Hat Virtualization Manager itself, Red Hat Virtualization can also take advantage of resources managed by external sources. The providers of these resources, known as external providers, can provide resources such as virtualization hosts, virtual machine images, and networks.

Red Hat Virtualization currently supports the following external providers:

Red Hat Satellite for Host Provisioning
Satellite is a tool for managing all aspects of the life cycle of both physical and virtual hosts. In Red Hat Virtualization, hosts managed by Satellite can be added to and used by the Red Hat Virtualization Manager as virtualization hosts. After you add a Satellite instance to the Manager, the hosts managed by the Satellite instance can be added by searching for available hosts on that Satellite instance when adding a new host. For more information on installing Red Hat Satellite and managing hosts using Red Hat Satellite, see the Red Hat Satellite Quick Start Guide and Red Hat Satellite Managing Hosts.
KubeVirt/Openshift Virtualization
Openshift Virtualization (formerly container-native virtualization or "CNV") enables you to bring virtual machines (VMs) into containerized workflows so you can develop, manage, and deploy virtual machines side-by-side with containers and serverless. In RHV Manager, adding this provider is one of the requirements for using Openshift Virtualization. For details, see Adding KubeVirt/Openshift Virtualization as an external provider.
OpenStack Image Service (Glance) for Image Management
OpenStack Image Service provides a catalog of virtual machine images. In Red Hat Virtualization, these images can be imported into the Red Hat Virtualization Manager and used as floating disks or attached to virtual machines and converted into templates. After you add an OpenStack Image Service to the Manager, it appears as a storage domain that is not attached to any data center. Virtual disks in a Red Hat Virtualization environment can also be exported to an OpenStack Image Service as virtual disks.
Note

Support for OpenStack Glance is now deprecated. This functionality will be removed in a later release.

VMware for Virtual Machine Provisioning
Virtual machines created in VMware can be converted using V2V (virt-v2v) and imported into a Red Hat Virtualization environment. After you add a VMware provider to the Manager, you can import the virtual machines it provides. V2V conversion is performed on a designated proxy host as part of the import operation.
RHEL 5 Xen for Virtual Machine Provisioning
Virtual machines created in RHEL 5 Xen can be converted using V2V (virt-v2v) and imported into a Red Hat Virtualization environment. After you add a RHEL 5 Xen host to the Manager, you can import the virtual machines it provides. V2V conversion is performed on a designated proxy host as part of the import operation.
KVM for Virtual Machine Provisioning
Virtual machines created in KVM can be imported into a Red Hat Virtualization environment. After you add a KVM host to the Manager, you can import the virtual machines it provides.
Open Virtual Network (OVN) for Network Provisioning
Open Virtual Network (OVN) is an Open vSwitch (OVS) extension that provides software-defined networks. After you add OVN to the Manager, you can import existing OVN networks, and create new OVN networks from the Manager. You can also automatically install OVN on the Manager using engine-setup.

To import virtual machines from a KVM external provider, see Importing a Virtual Machine from a KVM Host in the Virtual Machine Management Guide.

2.9.2.7. Adding Open Virtual Network (OVN) as an External Network Provider

You can use Open Virtual Network (OVN) to create overlay virtual networks that enable communication among the virtual machines without adding VLANs or changing the infrastructure. OVN is an extension of Open vSwitch (OVS) that provides native support for virtual L2 and L3 overlays.

You can also connect an OVN network to a native Red Hat Virtualization network. See Connecting an OVN Network to a Physical Network for more information. This feature is available as a Technology Preview only.

The ovirt-provider-ovn exposes an OpenStack Networking REST API. You can use this API to create networks, subnets, ports, and routers. For details, see OpenStack Networking API v2.0.

For more details, see the Open vSwitch Documentation and Open vSwitch Manpages.

2.9.2.7.1. Installing a New OVN Network Provider

Installing OVN using engine-setup performs the following steps:

  • Sets up an OVN central server on the Manager machine.
  • Adds OVN to Red Hat Virtualization as an external network provider.
  • On the Default cluster only, sets the Default Network Provider to ovirt-provider-ovn.
Important
  • Installing OVN changes the Default Network Provider setting on the Default cluster only, not on other clusters.
  • Changing the Default Network Provider setting does not update hosts in that cluster to use the Default Network Provider.
  • For hosts and virtual machines to use OVN, perform the addition tasks described in the "Next steps" at the end of this topic.

Procedure

  1. Optional: If you use a preconfigured answer file with engine-setup, add the following entry to install OVN: 

    OVESETUP_OVN/ovirtProviderOvn=bool:True
  2. Run engine-setup on the Manager machine.

  3. If you do not use a preconfigured answer file, answer Yes when the engine-setup asks: 

    Configuring ovirt-provider-ovn also sets the Default cluster's default network provider to ovirt-provider-ovn.
Non-Default clusters may be configured with an OVN after installation.
Configure ovirt-provider-ovn (Yes, No) [Yes]:

  4. Answer the following question: 

    Use default credentials (admin@internal) for ovirt-provider-ovn (Yes, No) [Yes]?:

    If Yes, engine-setup uses the default engine user and password specified earlier in the setup process. This option is only available during new installations. 

    oVirt OVN provider user[admin]:
oVirt OVN provider password[empty]:

    You can use the default values or specify the oVirt OVN provider user and password.

Note

To change the authentication method later, you can edit the /etc/ovirt-provider-ovn/conf.d/10_engine_setup.conf file, or create a new /etc/ovirt-provider-ovn/conf.d/20_engine_setup.conf file. Restart the ovirt-provider-ovn service for the change to take effect. See oVirt external network provider for OVN for more information about OVN authentication.

Next steps

Before you can create virtual machines that use a newly-installed OVN network, complete these additional steps:

  1. Add a network to the Default cluster.

    1. While doing so, select the Create on external provider check box. This creates a network based on ovirt-provider-ovn.
    2. Optional: To connect the OVN network to a physical network, select the Connect to physical network check box and specify the Red Hat Virtualization network to use.
    3. Optional: Determine whether the network should use a security group and select one from the Security Groups drop-down. For more information on the available options see Logical Network General Settings Explained.
  2. Add hosts to or reinstall the hosts on the Default cluster so they use the cluster’s new Default Network Provider, ovirt-provider-ovn.

  3. Optional: Edit non-Default clusters and set Default Network Provider to ovirt-provider-ovn.

    1. Optional: Reinstall the hosts on each non-Default cluster so they use the cluster’s new Default Network Provider, ovirt-provider-ovn.

2.9.2.7.2. Updating the OVN Tunnel Network on a Single Host

You can update the OVN tunnel network on a single host with vdsm-tool: 

# vdsm-tool ovn-config OVN_Central_IP Tunneling_IP_or_Network_Name Host_FQDN
Note

The Host_FQDN must match the FQDN that is specified in the engine for this host.

Example 2.4. Updating a Host with vdsm-tool

# vdsm-tool ovn-config 192.168.0.1 MyNetwork MyFQDN
2.9.2.7.3. Connecting an OVN Network to a Physical Network
Important

This feature relies on Open vSwitch support, which is available only as a Technology Preview in Red Hat Virtualization. Technology Preview features are not supported with Red Hat production service level agreements (SLAs), might not be functionally complete, and Red Hat does not recommend using them for production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information on Red Hat Technology Preview features support scope, see Technology Preview Features Support Scope.

You can create an external provider network that overlays a native Red Hat Virtualization network so that the virtual machines on each appear to be sharing the same subnet.

Important

If you created a subnet for the OVN network, a virtual machine using that network will receive an IP address from there. If you want the physical network to allocate the IP address, do not create a subnet for the OVN network.

Prerequisites

  • The cluster must have OVS selected as the Switch Type. Hosts added to this cluster must not have any pre-existing Red Hat Virtualization networks configured, such as the ovirtmgmt bridge.
  • The physical network must be available on the hosts. You can enforce this by setting the physical network as required for the cluster (in the Manage Networks window, or the Cluster tab of the New Logical Network window).

Procedure

  1. Click Compute Clusters.
  2. Click the cluster’s name. This opens the details view.
  3. Click the Logical Networks tab and click Add Network.
  4. Enter a Name for the network.
  5. Select the Create on external provider check box. ovirt-provider-ovn is selected by default.
  6. Select the Connect to physical network check box if it is not already selected by default.

  7. Choose the physical network to connect the new network to:

    • Click the Data Center Network radio button and select the physical network from the drop-down list. This is the recommended option.

    • Click the Custom radio button and enter the name of the physical network. If the physical network has VLAN tagging enabled, you must also select the Enable VLAN tagging check box and enter the physical network’s VLAN tag.

      Important

      The physical network’s name must not be longer than 15 characters, or contain special characters.

  8. Click OK.
