Subject: [PATCH] qemu: Don't emit SUSPENDED_POSTCOPY event on destination

When pause-before-switchover QEMU capability is enabled, we get STOP
|
|
|
fbe740 |
event before MIGRATION event with postcopy-active state. To properly
|
|
|
fbe740 |
handle post-copy migration and emit correct events commit
|
|
|
fbe740 |
v4.10.0-rc1-4-geca9d21e6c added a hack to
|
|
|
fbe740 |
qemuProcessHandleMigrationStatus which translates the paused state
|
|
|
fbe740 |
reason to VIR_DOMAIN_PAUSED_POSTCOPY and emits
|
|
|
fbe740 |
VIR_DOMAIN_EVENT_SUSPENDED_POSTCOPY event when migration state changes
|
|
|
fbe740 |
to post-copy.
|
|
|
fbe740 |
|
|
|
fbe740 |
However, the code was effective on both sides of migration resulting in
|
|
|
fbe740 |
a confusing VIR_DOMAIN_EVENT_SUSPENDED_POSTCOPY event on the destination
|
|
|
fbe740 |
host, where entering post-copy mode is already properly advertised by
|
|
|
fbe740 |
VIR_DOMAIN_EVENT_RESUMED_POSTCOPY event.
