I've done it in the past by creating a snapshot of a VM and then cloning
the snapshot and selecting preallocated for the cloned disks (if you have
to do it without powering off the source VM)
Or directly creating a clone of the VM if it is powered off, I think it
creates a full preallocated copy and btw you have no way to tell to clone
as thin if I remember correctly
