qmp_cont() supports the "autostart" variable:
if (runstate_check(RUN_STATE_INMIGRATE)) {
autostart = 1;
} else {
That's since commit 1e9981465f ("qmp: handle stop/cont in INMIGRATE
state"). The commit message also mentioned libvirt used to use a loop
somehow.. and I'm surprised to know it wasn't trying to fix the libvirt
problem but something else..
That makes sense, as any delay on cont would be accounted as downtime (even
if trivially), if only executed after loading complete event.
