In this case, shouldn't that be done by the upload-disk API ? When you
upload a VM, oVirt knows what to do with it and handle the locking and any
operations required to make the VM an oVirt VM.

This is trickier than you think. For LVM volumes somebody (VDSM) has to
lock and prepare the disks for you first and there is no external API to
do that AFAIK.
