Commit Message

CA-422282 Fix race condition about xenops cache (#6813)

There is race condition about vm cache between pool_migrate_complete and
VM event.
In the cross-pool migration case, it is designed to create vm with
power_state Halted in XAPI db. In pool_migrate_complete, add_caches
create an empty xenops_chae for the VM, then refresh_vm compares the
cache powerstate None with its real state Running to update the right
powerstate to XAPI db.
In the fail case, it is found that:
-> VM event 1 update_vm
-> pool_migrate_complete add_caches (cache power_state None)
-> pool_migrate_complete refresh_vm
-> VM event 1 update cache (cache power_state Running)
-> VM event 2 update_vm (Running <-> Running, XAPI DB not update)
When pool_migrate_complete add_caches, the cache update of previous VM
event 1 breaks the design intention.

This commit add a wait in pool_migrate_complete to ensure all in-flight
events complete before add_caches. Then there will be no race condition.
