      Description of problem:

      Deployed OPENSHIFT VIRTUALIZATION + ODF (internal mode) + HyperShift, created a managed control plane and used VIRT as worker nodes.

      It is currently found that after creating a PV on the managed cluster, the dynamically bound storage cannot be found when the node where the PV is located is restarted via the OCP-V UI.

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

      OPENSHIFT version 4.16.23

      How reproducible:
      Steps to Reproduce:
      1. Create a PV on the managed cluster, and attach to a pod
      2. Reboot the worker node where is the pod located in the OCP-V UI
      3. We can see the corresponding virt-launcher-xxxx pod is restarted

      Actual results:
      The pod failed to start due to the missing storage
      Couldn't find the storage information in the virtualmachineinstance and the corresponding virt-launcher-xxxx pod

      Expected results:
      The storage can be persistent after VM's rebooting

      Additional info:

      The issue doesn't happen when running reboot in the VM
