+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.
