Hello,
I'm running libvirt 1.2.2 and QEMU 1.7.91 on an Ubuntu 12.04LTS
host.
Prior to a recent upgrade, I've been able to run FreeBSD guests
(both
10.0 and 9.2) perfectly fine without issue. Now, this the
aforementioned versions, I'm running into a kernel panic almost
immediately after booting, same message with both 10.0 & 9.2:
"Fatal
trap 12: page fault while in kernel mode".
To ensure that it had nothing to do with my configuration [of the
guest OS] I've tried installing the guest from guest using
virt-install, however I still run into the same kernel panic. It'll
be hard for me to post the output of the panic, so I'll try to show
as
much info as possible via images[1].
Upon researching, I've come across a few threads (e.g., this one[2])
that appear to be related, but none have helped. Any information
that
you can provide to help me get to the root of this issue would be
greatly appreciated!

After using my noggin a bit, I've determine the culprit to be atkbd.
If
I disable it via the bootloader with "set hint.atkbd.0.disabled=1",
the
vm will boot fine. HOWEVER, my problem then is that I cannot use the
keyboard via VNC. I'm trying to figure out ways around this...any
help
would be much appreciated. I've already tried setting different
flags
for atkbd, but no matter which flag I set, I get the kernel panic --
ostensibly because atkbd is enabled (as it must be for a flag to be
set
for it).
I think you have hit this issue for which the workaround is a patch
to seabios:

Hm for some reason that link got truncated, try this one:

Lol, yeah, I was gonna say...but thanks! Not sure if I'm into
implementing a patch vs. finding a way around this, and I'm wondering
why it reared it's head after an update to libvirt & qemu vs. earlier in
my testing -- makes me think it may be an unrelated, albeit similar bug.
Thanks again Juergen.
