Hello,
On FreeBSD 7-STABLE, qemu refuses to exit even after the window is closed.
It is stuck so badly that even kill -9 fails to stop it. I looked in top to
see what it was doing that would cause it to lock so badly:
PID USERNAME THR PRI NICE SIZE RES STATE TIME WCPU COMMAND
34859 root 1 -8 20 433M 416M devdrn 9:49 0.00% qemu
I believe the problem is that qemu for some reason refuses to stop trying
to use the kqemu device.
I am running the latest qemu (0.9.1). I can provide a backtrace on request
(I'm really busy right now with other things, so I didn't have time to
attach one).
Yeah this looks like its the same FreeBSD 7.x/SMP issue that I already
got reports of (refcount problem, similar to what has already been fixed
once, only this time it seems to be a race...)
If it is, you should be able to work around it by using an uniprocessor
host kernel until a fix is known.
Sorry...
