Public bug reported:
Binary package hint: qemu-kvm
Repeatable. Triggered by high disk use. (when I run an rsync backup from
remote host.) Guest is also crashing during guest fdisk checks at
bootup. In this case, guest thread on server is not showing high cpu
use. This is the only guest this happens on. This guest is unique in
that is it running -cpu qemu32, and its disk bus is IDE as opposed to
virtio.
/var/log/messages on guest instance shows the following,
