Subject: [PATCH] qemu: Don't emit SUSPENDED_POSTCOPY event on destination
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When pause-before-switchover QEMU capability is enabled, we get STOP
event before MIGRATION event with postcopy-active state. To properly
handle post-copy migration and emit correct events commit
v4.10.0-rc1-4-geca9d21e6c added a hack to
qemuProcessHandleMigrationStatus which translates the paused state
reason to VIR_DOMAIN_PAUSED_POSTCOPY and emits
VIR_DOMAIN_EVENT_SUSPENDED_POSTCOPY event when migration state changes
to post-copy.

However, the code was effective on both sides of migration resulting in
a confusing VIR_DOMAIN_EVENT_SUSPENDED_POSTCOPY event on the destination
host, where entering post-copy mode is already properly advertised by
VIR_DOMAIN_EVENT_RESUMED_POSTCOPY event.
