You might want to try Konrad's branch for now:

http://git.kernel.org/?p=linux/kernel/git/konrad/xen.git

There may be some patches that have not been merged yet that apply to
your situation. For example, I believe some VGA stuff will not make it
into the kernel until 3.1

If that kernel doesn't work for you, then use the suggestions on this
page to maximize xen and kernel output and post all relevant logs to
the xen-devel mailing list.

Thanks,
Todd
