virsh: Always run event loop
Since virsh already implements event loop, it has to also run it. So far the event loop was only running during virsh console command.
Ahhh, I had discounted that because the date was Oct 11, and I figured we would have seen it by now. But that's just your original commit date, the merge date was Oct 24th. So yeah, I reckon this must be the culprit
I've been seeing this fairly often (about 25% of my 'make check' runs) since at least last Wednesday, on F16 when compiling at -O0; and the analysis of a race caused by not locking around ctl->quit seems like a reasonable culprit. -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
