This probably could be implemented through a CRM command and would be nice
to have in the long-run. The more HA and non-HA resources can be managed
the same the better, as otherwise it's causing friction to use HA.
The same holds for the qemu-server patch.
But, I'm fine with doing this separately later on, as this on its own is
already an improvement for quite a few users.
