My current usage of oVirt requires me to switch the boot priorities for virtual machines
from hard disk to pxe fairly often.
It would be nice to see an option added in that would set a one-off pxe boot for virtual
machines, reverting back to the original boot priorities after restart.
This would save some time when dealing with multiple machines, by eliminating the need to
switch them to pxe and then back to their previous boot options in the middle of their
boot process.
