So I've managed to get my dom0 booting on top of xen however now I'm
running into a problem where my domU is kernel oopsing on startup. The
traces I've gotten seem to be in the memory allocation functions.
Normally this is a sign of memory corruption. Considering this VM was
working perfectly with the 2.6.31.10 dom0 based on the Novell patches
and xen 4.0 I don't think it is the VM that is the problem (however I
can try starting it under kvm to be certain. Any suggestions on what I
can do to try to hunt down the memory corruption?

Dave
