Deploy the OpenShift Virtualization Operator

  1. Deploy the OpenShift Virtualization Operator

    cat << EOF | oc apply -f -
    apiVersion: v1
    kind: Namespace
    metadata:
      name: openshift-cnv
    ---
    apiVersion: operators.coreos.com/v1
    kind: OperatorGroup
    metadata:
      name: kubevirt-hyperconverged-group
      namespace: openshift-cnv
    spec:
      targetNamespaces:
        - openshift-cnv
    ---
    apiVersion: operators.coreos.com/v1alpha1
    kind: Subscription
    metadata:
      name: hco-operatorhub
      namespace: openshift-cnv
    spec:
      source: redhat-operators
      sourceNamespace: openshift-marketplace
      name: kubevirt-hyperconverged
      startingCSV: kubevirt-hyperconverged-operator.v4.15.1
      channel: "stable"
    EOF
    
  2. If you want to see the progress of the operator you can log into the OpenShift Console (hint run oc whoami --show-console to get the URL)

  3. Create an OpenShift Virtualization operand

    Note: this is all defaults, so will not support a lot of the more advanced features you might want such as live migration.

    cat << EOF | oc apply -f -
    apiVersion: hco.kubevirt.io/v1beta1
    kind: HyperConverged
    metadata:
      name: kubevirt-hyperconverged
      namespace: openshift-cnv
      annotations:
        deployOVS: "false"
      labels:
        app: kubevirt-hyperconverged
    spec:
      applicationAwareConfig:
        allowApplicationAwareClusterResourceQuota: false
        vmiCalcConfigName: DedicatedVirtualResources
      certConfig:
        ca:
          duration: 48h0m0s
          renewBefore: 24h0m0s
        server:
          duration: 24h0m0s
          renewBefore: 12h0m0s
      evictionStrategy: LiveMigrate
      featureGates:
        alignCPUs: false
        autoResourceLimits: false
        deployKubeSecondaryDNS: false
        deployTektonTaskResources: false
        deployVmConsoleProxy: false
        disableMDevConfiguration: false
        enableApplicationAwareQuota: false
        enableCommonBootImageImport: true
        enableManagedTenantQuota: false
        nonRoot: true
        persistentReservation: false
        withHostPassthroughCPU: false
      infra: {}
      liveMigrationConfig:
        allowAutoConverge: false
        allowPostCopy: false
        completionTimeoutPerGiB: 800
        parallelMigrationsPerCluster: 5
        parallelOutboundMigrationsPerNode: 2
        progressTimeout: 150
      resourceRequirements:
        vmiCPUAllocationRatio: 10
      uninstallStrategy: BlockUninstallIfWorkloadsExist
      virtualMachineOptions:
        disableFreePageReporting: false
        disableSerialConsoleLog: true
      workloadUpdateStrategy:
        batchEvictionInterval: 1m0s
        batchEvictionSize: 10
        workloadUpdateMethods:
        - LiveMigrate
      workloads: {}
    EOF
    
  4. New “Virtualization” Section in the OpenShift Console

    Once the operator is installed you should see a new “Virtualization” section in the OpenShift Console (you may be prompted to refresh the page)

  5. Close the popup window and click the “Download virtctl” button to download the virtctl binary.
