Mice Xia commented on CLOUDSTACK-118:
-------------------------------------
no clue for the exception which xenserver throws, but indeed there is a race
condition between migrating thread and delta sync thread, i.e. delta sync
thread might force-update VM's status during VM migration, and that will cause
migrating thread fail to update VM status.
Plus, can not cancel maintenance because there is no such state transition in
resource state machine.
