Start the VM 2. Dump the VM xml 3. Destroy 4. Add "<boot order="X" /> to every disk entry in the dump file 5. virsh define VM.xml 6. virsh start VM Sadly I can't set more than 1 disk as bootable in oVirt.

There was recently issue [1] with specific lvm version (lvm2-2.03.14-1.el8.x86_64) which could cause boot failures.
