Installing OKD Virtualization using the <strong>cli</strong> - Installing | Virtualization

Prerequisites
Subscribing to the OKD Virtualization catalog by using the cli
Deploying the OKD Virtualization Operator by using the cli
Next steps

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.

To specify the nodes where you want OKD Virtualization to install its components, configure node placement rules.

Prerequisites

Install OKD 4.12 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

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.v4.12.14
  channel: "stable" (1)

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

Create the required Namespace, OperatorGroup, and Subscription objects for OKD Virtualization by running the following command:
```
$ oc apply -f <file name>.yaml
```

You can configure certificate rotation parameters in the YAML file.

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

Create a YAML file that contains the following manifest:

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

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.v4.12.14   OKD Virtualization   4.12.14                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.
