OCP Admin Portal -> Virtualization Tab -> Note VM running with Not Migratable status -> Select the VM name -> Toggle to metrics and then click back again to overview. -> Notice Not Migratable tag is gone  -> Select Actions -> Select Migrate. -> Confirmed VM Live migrates works.

// VMs satisfy the pre-req's for Live Migrate.

1. Create a virtual machine with RWX storage that meets the prerequisites for live migration.
2. Notice VM running status with Not Migrateable from all projects view.
3. Select VM Toggle to metrics and then click back again to overview. 

VMs shows in-correct status as Not Migrate able.

VMs should show correct status migrate able. 

In my lab, everytime when I open VMs running on all namespaces shows non-migrate able status for all VMs and stays around 30 seconds and disappear.
