      Description of problem:

      [1] Created a new VM and is having below PVC:

      rhel8-tory-koala Bound pvc-6bafb6a3-e418-4860-91b2-f80af872a11f 30Gi RWX ocs-external-storagecluster-ceph-rbd 24s

      [2] Created a clone from this VM:

      rhel8-tory-koala-clone-rhel8-tory-koala-1m97p Bound pvc-90e296b3-20ba-40d4-b0b7-5d9769ae2657 30Gi RWX ocs-external-storagecluster-ceph-rbd 4s

      [3] Created a snapshot on the cloned VM:

      NAME READYTOUSE SOURCEPVC SOURCESNAPSHOTCONTENT RESTORESIZE SNAPSHOTCLASS SNAPSHOTCONTENT CREATIONTIME AGE
      vmsnapshot-70be6e17-b80d-46fb-a544-c52f6ee76a61-volume-rhel8-tory-koala true rhel8-tory-koala-clone-rhel8-tory-koala-1m97p 30Gi ocs-external-storagecluster-rbdplugin-snapclass snapcontent-4ce6eab1-62b0-42f1-bd72-f4a0a2d63dae 19s 20s

      [4] Deleted the VM and disk in [1].

      [5] Tried to restore the snapshot. Restoration failed with the error below:

      ~~~
      Error creating DataVolume restore-558e00db-857b-415d-8f37-bd7369194419-rhel8-tory-koala: admission webhook "datavolume-validate.cdi.kubevirt.io" denied the request: Source PVC default/rhel8-tory-koala not found
