Mailing lists can often be a better way to get help from developers, so
posting here is no problem.

Also, fedora-virt redhat com might be a better place to post questions
these days - it's not clear whether the fedora-xen list has a future.

You've seen this then, right?

Okay, sounds like it might "just" be a F10 kernel bug.

Try doing this to get a stack trace:

  1) Set "on_crash=preserve" in your domain config

  2) Copy the guest kernel's System.map to the host

  2) Once the guest has crashed, run:

       /usr/lib/xen/bin/xenctx -s System.map <domid>
