Removing leftover resources from container-native virtualization 2.1 uninstallation

Uninstalling container-native virtualization 2.1 does not remove all container-native virtualization resources from the cluster. These resources prevent the openshift-cnv namespace from being deleted and prevents re-installation of container-native virtualization. This content is not included.BZ#1757705, This content is not included.BZ#1712429

The workaround is to manually delete these resources and the openshift-cnv namespace.

Procedure

1. The hco-operator Cluster Service Version (CSV) remains in one or more namespaces. Use the following command to find and delete these CSVs:

   1. List the namespaces that have the kubevirt-hyperconverged-operator CSV:

       $ oc get csv --all-namespaces | grep kubevirt-hyperconverged-operator
      

   2. Delete each CSV from the namespaces listed in the previous step. Run this command for each of the namespaces:

       $ oc delete csv kubevirt-hyperconverged-operator -n <namespace>
      

2. Delete the following resources:

    $ oc delete service kubemacpool-service -n openshift-cnv
    $ oc delete og hco-catalogsource -n openshift-marketplace
    $ oc delete apiservices v1alpha3.subresources.kubevirt.io -n openshift-cnv
   

3. Delete the openshift-cnv namespace:

    $ oc delete ns openshift-cnv
