Subject: [PATCH] qemu: Don't ignore resume events
5ff110
5ff110
Since commit v4.7.0-302-ge6d77a75c4 processing RESUME event is mandatory
5ff110
for updating domain state. But the event handler explicitly ignored this
5ff110
event in some cases. Thus the state would be wrong after a fake reboot
5ff110
or when a domain was rebooted after it crashed.
5ff110
5ff110
BTW, the code to ignore RESUME event after SHUTDOWN didn't make sense
5ff110
even before making RESUME event mandatory. Most likely it was there as a
5ff110
result of careless copy&paste from qemuProcessHandleStop.
5ff110
5ff110
The corresponding debug message was clarified since the original state
5ff110
does not have to be "paused" only and while we have a "resumed" event,
5ff110
the state is called "running".
