Description of problem:

Live migration of OpenShift Virtualization VMs with ODF based shared disks (with RWX access mode) is failing with exceptions like:

"error encountered sending command SyncVMI.."

Version-Release number of selected component (if applicable):

4.8.2

How reproducible: nearly 100%

Steps to Reproduce:
1. Create an OpenShift Virtualization VM with disks based on openshift-ceph storage, shared access RWX of underlying PVC
2. Start Migration action using "Actions ==> Migrate"
3. Observe that VM gets into "Paused" state and check Events in the corresponding OpenShift UI Tab

Actual results:

Observed exception: ""Generated from virt-handler
219 times in the last 12 hours
unknown error encountered sending command SyncVMI: rpc error: code = DeadlineExceeded desc = context deadline exceeded"

Expected results:

VM gets migrated to another OCP node preserving its state (storage based on RWX PVC)

Additional info:

Please see attached exports of VMs and corresponding KubeVirt POD YAML descriptors for VM that fails to Migrate. Can provide access to the Lab OCP cluster where the issue is observed
