RE: [PATCH 02/10] Fix the qemu crash when guest shutdown during checkpoint
If user executes the shutdown normally and QEMU crashes, I think this is
unacceptable.
Since we can avoid this situation, why not do it?
Thanks,
Lei.

This patch fixes the 'colo' -> 'shutdown' transition. AFAIK then
colo_do_checkpoint_transaction will call vm_start() again, which does
'shutdown' -> 'running' and (rightfully) crashes. So I think it is better to
crash here too.

This patch fixes the 'colo' -> 'shutdown' transition. AFAIK then
colo_do_checkpoint_transaction will call vm_start() again, which
does 'shutdown' -> 'running' and (rightfully) crashes. So I think
it is better to crash here too.

RE: [PATCH 02/10] Fix the qemu crash when guest shutdown during checkpoint
The state will be set RUN_STATE_COLO in colo_do_checkpoint_transaction(). If
the guest executes power off or shutdown at this time and the QEMU main thread
will call vm_shutdown(), it will set the state to RUN_STATE_SHUTDOWN.
The state switch from RUN_STATE_COLO to RUN_STATE_SHUTDOWN is not defined in
runstate_transitions_def. this will cause QEMU crash. Although this is small
probability, it may still happen. By the way. Do you have any comments about
other patches?
Thanks,
Lei.

RE: [PATCH 02/10] Fix the qemu crash when guest shutdown during checkpoint
The Primary VM can be shut down when it is in COLO state, which may trigger
this bug.
About 'shutdown' -> 'colo' -> 'running', I think you are right, I did have the
problems you said. For 'shutdown'->'colo', The fixed
patch(5647051f432b7c9b57525470b0a79a31339062d2) have been merged.
Recently, I found another bug as follows in the test.
qemu-system-x86_64: invalid runstate transition: 'shutdown' -> 'running'
Aborted (core dumped)
The gdb bt as following:

I wonder how that is possible, since the VM is stopped during 'colo' state.
Unrelated to this patch, I think this area needs some work since the following
unintended runstate transition is possible:
'shutdown' -> 'colo' -> 'running'.
