Thanks to the previous commit the RESUME event handler knows what reason
|
|
|
5ff110 |
should be used when changing the domain state to VIR_DOMAIN_RUNNING, but
|
|
|
5ff110 |
the emitted VIR_DOMAIN_EVENT_RESUMED event still uses a generic
|
|
|
5ff110 |
VIR_DOMAIN_EVENT_RESUMED_UNPAUSED detail. Luckily, the event detail can
|
|
|
5ff110 |
be easily deduced from the running reason, which saves us from having to
|
|
|
5ff110 |
pass one more value to the handler.
