I'd like whatever information you can provide about the domU panic. It
should dump you into the kernel debugger. Please type "bt" at the
(ddb) prompt and then provide me with a copy of the domU console
output. Don't kill the domain either; I may ask for further ddb
commands.
Here is a full log and the output of bt :
The fsck bit is because of previous crash :-(

Welcome to FreeBSD!
Before seeking technical support, please use the following resources:
o Security advisories and updated errata information for all
releases are
at http://www.FreeBSD.org/releases/ - always consult the ERRATA
section
for your release first as it's updated frequently.
o The Handbook and FAQ documents are at http://www.FreeBSD.org/ and,
along with the mailing lists, can be searched by going to
http://www.FreeBSD.org/search/. If the doc distribution has
been installed, they're also available formatted in /usr/share/doc.
If you still have a question or problem, please take the output of
`uname -a', along with any relevant error messages, and email it
as a question to the [email protected] mailing list. If you are
unfamiliar with FreeBSD's directory layout, please refer to the hier(7)
manual page. If you are not familiar with manual pages, type `man man'.
You may also use sysinstall(8) to re-enter the installation and
configuration utility. Edit /etc/motd to change this login
announcement.
