I have something to confess: I installed qemu (qemu-0.9.0-i386.tar.gz),
too. Needed that qemu-img to convert an raw to a qcow.
Removed all the files from the package now, rebooted then, but still
Dom0 crashes.
The guest crashing the Dom0 is not using that qcow image.

RHEL 5, and thus CentOS 5, both have auto-updates turned on by default
with yum-updatesd. I consider this *insane*, since it will patch things
without a chance to say "hmm, I'm busy today, let's not do that Xen
kernel patch right now!".
Can you bring up the machine without Xen and check /var/log/rpmpkgs,
created by /etc/cron.daily/rpm, to check the software you've installed?
