Over the last two months, since our last round of patching, we have experienced several libvirt guests crashing with this in the qemu 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. This appears to be the same problem being experienced by a user who has filed bugs against QEMU and CentOS: http://bugs.centos.org/view.php?id=6928 https://bugs.launchpad.net/qemu/+bug/1268671 Our software versions are: libvirt-0.10.2-18.el6_4.14.x86_64 qemu-kvm-0.12.1.2-2.415.el6.x86_64 We have not successfully determined what seems to prompt the crash. The guests are running in different hardware and dedicated to different tasks (DNS server, MySQL server, hosting a jboss application, etc). Out of a population of a few hundred servers we seem to get about one crash a week, apparently randomly. I can't find any evidence that the problem is being worked on - is anyone else experiencing this issue since the last round of updates to 6.4, and if so, have you discovered a workaround or solution? I appreciate any insight anyone can provide. Adrian
