Unfortunately, fence_ack_manual only works if executed on the fence master.
So it is not trivial to implement. I am also unsure if we want to put
that on the GUI - it's considered very dangerous (a simple button press can 
result I a split brain!).

Yes - I simply had no time to implement that.

Yes. Maybe we should implement a 'qm mirtate-from' command?
