KubeVirt Hyperconverged is not yet supported on an OpenShift cluster configured with single stack IPv6. It’s progress is being tracked on this issue.

Impact

    $ kubectl describe network cluster

Mitigation

It is recommended to use single stack IPv4 or a dual stack IPv4/IPv6 networking to use KubeVirt Hyperconverged. Refer the documentation.
