In regular KVM thin disks can be made fully preallocated when you 'expand' them to the predefined maximum size. Usually I create a large file and then I delete it. Something like this: 'dd if=/dev/zero of=/path/to/mounted/qcow2/disk/largefile bs=4M status=progress ; rm -f /path/to/mounted/qcow2/disk/largefile I doubt it's different in oVirt as backend is the same (KVM/qemu/raw or qcow2).

Hi Jorge,
Currently, there is no mechanism for doing this operation on the disk, but there is workaround such as:
- Export the VM as OVA or to an export domain and import it back with the needed allocation method.
