Public bug reported: During system update/upgrade in the host machine, all guest machines crashed. Looking at the apt logs we can see that libvirt packages have been upgraded during that process. Older libvirt packages are known to stop guests however in Lucid this is not suppose to happen.
Please take a look at the logs below. This issue can not be reproduced since it happened in the production server. The host machine has 24 CPUs and all guests are running the virtio driver for the network. Please provide some input regarding this issue and let me know if you guys need something else in order to debug the issue.
