The root cause is when the guest shutdown, the state of VM will switch COLO to SHUTDOWN. When do checkpoint again, the state will be changed to COLO. But the state switch is undefined in runstate_transitions_def, we should add it. This patch fixes the following: qemu-system-x86_64: invalid runstate transition: 'shutdown' -> 'colo' Aborted Signed-off-by: leirao Signed-off-by: Zhang Chen Reviewed-by: Zhang Chen --- softmmu/vl.c | 1 + 1 file changed, 1 insertion(+) diff --git a/softmmu/vl.c b/softmmu/vl.c index 5a11a62f78..bafe7c5b70 100644 --- a/softmmu/vl.c +++ b/softmmu/vl.c @@ -632,6 +632,7 @@ static const RunStateTransition runstate_transitions_def[] = { { RUN_STATE_SHUTDOWN, RUN_STATE_PAUSED }, { RUN_STATE_SHUTDOWN, RUN_STATE_FINISH_MIGRATE }, { RUN_STATE_SHUTDOWN, RUN_STATE_PRELAUNCH }, + { RUN_STATE_SHUTDOWN, RUN_STATE_COLO }, { RUN_STATE_DEBUG, RUN_STATE_SUSPENDED }, { RUN_STATE_RUNNING, RUN_STATE_SUSPENDED },
