Subject: [PATCH] qemu: Map running reason to resume event detail
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Thanks to the previous commit the RESUME event handler knows what reason
should be used when changing the domain state to VIR_DOMAIN_RUNNING, but
the emitted VIR_DOMAIN_EVENT_RESUMED event still uses a generic
VIR_DOMAIN_EVENT_RESUMED_UNPAUSED detail. Luckily, the event detail can
be easily deduced from the running reason, which saves us from having to
pass one more value to the handler.
