I ran into the exact same thing on an install a few days ago. I did not
run into it with rc-6.

This looks like something trying to set the NX bit in a mapping, which
should be fine on this processor. Could it be disabled in BIOS or
something?

Hm, OK. Maybe the problem is that we haven't enabled NX in EFER at that
early point. I'll cook something up.

Well, for some reason, the BIOS had NX disabled by default. After
enabling, I can now get further. I've attached the output I'm now
seeing. Could this now be related to the myoung kernel?
Many thanks.

OK, good to know. I'll post a patch shortly which I hope will make it
work either way.

It's crashing because dom0 is trying to manipulate the DMAR hardware,
which Xen won't allow. I think there's a fix in Xen to hide the DMAR
from dom0, but in the meantime you can disable it in BIOS.

Subject: [PATCH] xen: check EFER for NX before setting up GDT mapping
x86-64 assumes NX is available by default, so we need to
explicitly check for it before using NX. Some first-generation
Intel x86-64 processors didn't support NX, and even recent systems
allow it to be disabled in BIOS.

kernel-2.6.31-1.2.67.xendom0.fc12.x86_64.rpm has this fix in if you want
to test it, at
http://koji.fedoraproject.org/koji/getfile?taskID=1681664&name=kernel-2.6.31-1.2.67.xendom0.fc12.x86_64.rpm
(the other kernel packages are available via
http://koji.fedoraproject.org/koji/taskinfo?taskID=1681662
) I haven't tested it so I don't know if it boots.

This absolutely fixes my issue. With the latest patch, I can boot my
system successfully if NX is enabled or disabled in the BIOS.
Just a final note, I do need to make sure VT-d is disabled in the
BIOS, and then I can boot. This was obviously not addressed in this
patch nor was it requested to be. It would be nice to have it working
at some point as this machine will hopefully have a bunch of NVidia
cards in it that will need to be dedicated to each of the domU's for
CUDA research.
Thank you all for your prompt and courteous responses. It makes me
proud to be a RHCE when I get support from a community of developers
like you guys.

Great, thanks for the confirmation. I'll push this patch upstream.

Just to clarify this a bit:
Are you saying that if you leave VT-d enabled in BIOS something bad
happens? Does it crash?
But ideally you'd like to enable it and have it working to allow
NVidia cards work, which require it?
Thanks,
J

This is coming from memory as I won't be in front of the machine
experiencing the issue for another three weeks. Gotta love paternity
leave. :)
From what I recall, if I leave VT-d enabled in the BIOS, I experience
the dom0 crash I had sent earlier as a .gz file. I can verify this at
a later date.
Ideally, I am looking to have the ability to assign the NVidia cards
to the individual domU machines for CUDA development. We want to see
how virtualization affects CUDA performance among other things.
The patch that you provided earlier now allows the machine to boot no
matter what the NX setting is in the BIOS.
Does that help clarify the situation?
