Subject: [PATCH] qemu: Don't ignore resume events
|
|
|
9c6c51 |
|
|
|
9c6c51 |
Since commit v4.7.0-302-ge6d77a75c4 processing RESUME event is mandatory
|
|
|
9c6c51 |
for updating domain state. But the event handler explicitly ignored this
|
|
|
9c6c51 |
event in some cases. Thus the state would be wrong after a fake reboot
|
|
|
9c6c51 |
or when a domain was rebooted after it crashed.
|
|
|
9c6c51 |
|
|
|
9c6c51 |
BTW, the code to ignore RESUME event after SHUTDOWN didn't make sense
|
|
|
9c6c51 |
even before making RESUME event mandatory. Most likely it was there as a
|
|
|
9c6c51 |
result of careless copy&paste from qemuProcessHandleStop.
|
|
|
9c6c51 |
|
|
|
9c6c51 |
The corresponding debug message was clarified since the original state
|
|
|
9c6c51 |
does not have to be "paused" only and while we have a "resumed" event,
|
|
|
9c6c51 |
the state is called "running".
