The guest should run after resetting it, but it does not run if its
old state is RUN_STATE_INTERNAL_ERROR or RUN_STATE_PAUSED.
We don't set runstate to RUN_STATE_PAUSED when resetting the guest,
so the runstate will be changed from RUN_STATE_INTERNAL_ERROR or
RUN_STATE_PAUSED
quring the status
of vm in destination host when migration completes.
