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

rhevm-backend-3.5.1-0.4.el6ev.noarch


Actual results:

VM disappears from RHEV-M with logical volumes still left on storage 

Expected results:

There was no command issues to remove the VM, VM should stay in RHEV after successful or failed clone operation
