I always thought that's commodity hardware .. oh well :-)

It's feasible, but currently not implemented. I also don't know enough  
of the s390x internals to do it as is :-). On S390 the hardware and OS  
handle most of the virtualization parts themselves.

Either way - let's focus on getting it working with KVM first!
