Description of problem:
Create a VM and wait for it becomes running, clone the VM, check the VM disk, it use the same PVC of the source VM, which is wrong as when this VM is up, the source VM is not able to turn up. And also it causes confused delete issues, from what I see the VM is stucking at terminating status forever when delete both of them at the same time.

It's happens on 4.12 and 4.13, regression from 4.11.
