KubeVirt

Limited vCluster Tenancy Configuration Support

This feature is only available when using the following worker node types:

  • Host Nodes
Enterprise-Only Feature

This feature is an Enterprise feature. See our pricing plans or contact our sales team for more information.

vCluster offers the possibility to reuse a KubeVirt installation of the host cluster within the vCluster. vCluster is able to sync KubeVirt resources from the vCluster to the host cluster and allows you to use virtctl within the vCluster.

Enable KubeVirt Integration​

To enable the integration, use the following configuration inside your vcluster.yaml:

integrations:
  kubeVirt:
    enabled: true
    # If you want vCluster to sync data volumes as well.
    #sync:
    #  dataVolumes:
    #    enabled: true

Next you can deploy and use KubeVirt resources inside the vCluster which will be synced to the host cluster.

Sync DataVolumes​

In order to sync KubeVirt DataVolumes, please make sure to install the KubeVirt Containerized Data Importer. Then enable the following setting in the vcluster.yaml:

integrations:
  kubeVirt:
    enabled: true
    sync:
      dataVolumes:
        enabled: true

After vCluster restarts, the DataVolumes CRD should be visible within the vCluster.

Limitations​

vCluster currently only supports syncing and using the following resources inside the vCluster:

  • VirtualMachine
  • VirtualMachineInstance
  • VirtualMachinePool
  • VirtualMachineClone
  • DataVolume (needs to be enabled via integrations.kubeVirt.sync.dataVolumes.enabled)

The following virtctl commands are supported:

  • virtctl start
  • virtctl stop
  • virtctl migrate
  • virtctl ssh
  • virtctl vnc
  • virtctl pause
  • virtctl unpause
  • virtctl scp
  • virtctl restart
  • virtctl port-forward
  • virtctl console
