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