If the checkpoint occurs when the guest finishes restarting
but has not started running, the runstate_set() may reject
the transition from COLO to PRELAUNCH with the crash log:

{"timestamp": {"seconds": 1593484591, "microseconds": 26605},\
"event": "RESET", "data": {"guest": true, "reason": "guest-reset"}}
qemu-system-x86_64: invalid runstate transition: 'colo' -> 'prelaunch'

Long-term testing says that it's pretty safe.

I'd expect this to get ack from the relevant maintainers.

The scripts/get_maintainer.pl can't find relevant maintainers for this patch.
Maybe Paolo have time to cover this simple patch related to runstate?

This looks OK to me;

Acked-by: Dr. David Alan Gilbert <dgilbert@redhat.com>

it should be fine to merge it along with the pull that takes the other
patches.
