As mentioned in the other mail, libvirt should be doing that when the VM
starts as shutoff.

I guess we could support it for a running VM as well, but we'd need to fully
stop the VM first and restart a new qemu process. That's not how libvirt does
it currently, so it's restricted to only switching between snapshots with
idential hw config.
