Hi @nashok I will really appreciate the yamls of the original VM, and of the cloned VM. Also an explanation of the process of the VM clone that was done in this case. Thanks
Attaching the yamls of VMs. The VM clone was done from the OpenShift console using "clone" option. Looks like the issue is because the VirtualMachineSnapshotContent of cloned VM refers to the source VM PVC instead of cloned PVC. ~~~ yq -y '.spec.source.virtualMachine.spec.dataVolumeTemplates' /tmp/vmsnapshot-content-53237ca8-7ca8-4894-ab85-0ba132a968e0.yaml - metadata: creationTimestamp: null name: rhel8-resident-heron-clone-rhel8-resident-heron-2vald spec: source: pvc: name: rhel8-resident-heron <<<< namespace: nijin-cnv storage: accessModes: - ReadWriteMany resources: requests: storage: 30Gi storageClassName: ocs-external-storagecluster-ceph-rbd volumeMode: Block ~~~ The restore works if I manually edit this and changed it to cloned PVC.
Added known issue to 4.11 release notes. @dafrank Please review: https://github.com/openshift/openshift-docs/pull/48328. Thank you.
