CentOS guest crashing due to assertion failure in qemu-char.c
Here is the log in /var/log/libvirt/qemu/centos_heavy.log
qemu-kvm: /builddir/build/BUILD/qemu-kvm-0.12.1.2/qemu-char.c:630: io_watch_poll_finalize: Assertion `iwp->src == ((void *)0)' failed.
2014-01-13 16:50:31.576+0000: shutting down
The code it's failing the assertion on has an interesting comment:
static void io_watch_poll_finalize(GSource *source)
{
/* Due to a glib bug, removing the last reference to a source
* inside a finalize callback causes recursive locking (and a
* deadlock). This is not a problem inside other callbacks,
* including dispatch callbacks, so we call io_remove_watch_poll
* to remove this source. A t this point, iwp->src must
* be NULL, or we would leak it.
*
* This would be solved much more elegantly by child sources,
* but we support older glib versions that do not have them.
*/
IOWatchPoll *iwp = io_watch_poll_from_source(source);
assert(iwp->src == NULL);
}
