Installing OKD Virtualization using the CLI

Install OKD Virtualization to add virtualization functionality to your OKD cluster. You can subscribe to and deploy the OKD Virtualization Operators by using the command line to apply manifests to your cluster.

Prerequisites

• Install OKD 4.10 on your cluster.

• Install the OpenShift CLI (oc).

• Log in as a user with cluster-admin privileges.

Subscribing to the OKD Virtualization catalog by using the CLI

Before you install OKD Virtualization, you must subscribe to the OKD Virtualization catalog. Subscribing gives the openshift-cnv namespace access to the OKD Virtualization Operators.

To subscribe, configure Namespace, OperatorGroup, and Subscription objects by applying a single manifest to your cluster.

Procedure

1. Create a YAML file that contains the following manifest:

   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.v4.10.0
     channel: "stable" (1)

   1	Using the stable channel ensures that you install the version of OKD Virtualization that is compatible with your OKD version.

2. Create the required Namespace, OperatorGroup, and Subscription objects for OKD Virtualization by running the following command:

   $ oc apply -f <file name>.yaml

Deploying the OKD Virtualization Operator by using the CLI

You can deploy the OKD Virtualization Operator by using the oc CLI.

Prerequisites

• An active subscription to the OKD Virtualization catalog in the openshift-cnv namespace.

Procedure

1. Create a YAML file that contains the following manifest:

   apiVersion: hco.kubevirt.io/v1beta1
   kind: HyperConverged
   metadata:
     name: kubevirt-hyperconverged
     namespace: openshift-cnv
   spec:

2. Deploy the OKD Virtualization Operator by running the following command:

   $ oc apply -f <file_name>.yaml

Verification

• Ensure that OKD Virtualization deployed successfully by watching the PHASE of the cluster service version (CSV) in the openshift-cnv namespace. Run the following command:

  $ watch oc get csv -n openshift-cnv

  The following output displays if deployment was successful:

  Example output

  NAME                                      DISPLAY                    VERSION   REPLACES   PHASE
  kubevirt-hyperconverged-operator.v4.10.0   OKD Virtualization   4.10.0                Succeeded

Next steps

You might want to additionally configure the following components:

• The hostpath provisioner is a local storage provisioner designed for OKD Virtualization. If you want to configure local storage for virtual machines, you must enable the hostpath provisioner first.
