I have about 100 old VM's in my cluster. They're powered down, ready for deletion. What I want to do is delete the VM's including disks without actually deleting the disk images from the storage array itself. Is that possible? At the end I want to be able to delete the storage domain (which then should not hold any data, as far as ovirt is concerned).

Reason for this: it's a ZFS pool with dedup enabled, deleting the images one by one will kill the array with 100% iowa for some time.
