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 -

   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.
