Subject: [PATCH] Fixed a QEMU hang when guest poweroff in COLO mode
|
|
|
|
cherry picked from commit 795969ab1fe6d5a0f524be92e2e1ecd13f1873eb
|
|
|
|
When the PVM guest poweroff, the COLO thread may wait a semaphore
|
|
in colo_process_checkpoint().So, we should wake up the COLO thread
|
|
before migration shutdown.
