Subject: [PATCH] i6300esb watchdog: bugfix: Add a runstate transition
|
||
|
|
|
||
|
|
QEMU will abort() for the reasons now:
|
||
|
|
|
||
|
|
invalid runstate transition: 'prelaunch' -> 'postmigrate'
|
||
|
|
Aborted
|
||
|
|
|
||
|
|
This happens when:
|
||
|
|
|<- watchdog timeout happened, then sets reset_requested to
|
||
|
|
| SHUTDOWN_CAUSE_GUEST_RESET;
|
||
|
|
|<- hot-migration thread sets vm state to RUN_STATE_FINISH_MIGRATE
|
||
|
|
| before the last time of migration;
|
||
|
|
|<- main thread gets the change of reset_requested and triggers
|
||
|
|
| reset, then sets vm state to RUN_STATE_PRELAUNCH;
|
||
|
|
|<- hot-migration thread sets vm state to RUN_STATE_POSTMIGRATE.
|
||
|
|
|
||
|
|
Then 'prelaunch' -> 'postmigrate' runstate transition will happen.
|
||
|
|
It is legal so add this transition to runstate_transitions_def.
