Actually, this leads to an interesting idea. How about a Xen VMM for the zSeries. z/VM aside, I'm talking about an open source VM implementation to run inside an LPAR. I wonder if IBM would assist in that project? ;)
Well, the way to start here would be to take Hercules, and then replace most of the instruction emulation pieces with straight calls to the instructions themselves; this works for all problem-mode instructions. Then look at how to take privileged instructions and dispatch 'em with SIE, I guess. Of course then you'd have to deal with device virtualization. So, uh, lotta work.
