I tried to create a new VM with a disk. Foreman didn't achieve to launch VM because oVirt was doing the '/bin/dd' to create a fully provisioned disk.
Foreman displayed the error 'Failed to power up a compute devovirt2 (oVirt) instance myvm.example.com: Cannot run VM: VM's image is locked.
Please try again in a few minutes.'
Foreman rolled back the VM creation and deleted VM, Disk and Nic on oVirt
