I thought I might have a poke at this, how do you go about reproducing
it? I've used your .config and it boots OK -- now I'm trying a kernbench
run since I think you mentioned compiling a kernel in domain 0 at one
point.

How much RAM does your host have? Are you running 32 or 64 bit
hypervisor? Which hypervisor version? From your .config I think your
dom0 kernel is 32 bit, right?

Ian.
