Hrm, that's very interesting. You may want to try posting to
xen-users at lists.xensource.com .
qemu without the kernel module is used extensively for Xen.
I wonder if the driver hasn't been modified well enough to use
hypercalls instead of operations that won't work in a Xenofied Linux
kernel. The dom0 and domU kernels run in ring 1. I think I remember
reading something on the QEMU website about QEMU's not working with
Xen as well, but am certain that a modified userspace version of it
gets used for fully virtualized Xen domU's.
Hope this helps!
