Can't help with the VM bit (for most people licensing is a problem
there) but I'll happily help people who want to add Linux/390 native
under Hercules on this image. It's less difficult than the strangeness
of it would seem to indicate. You really don't have to worry about the
fact that a 390 (or, more like, a 64-bit zSeries) doesn't have a bus in
the normal sense. Or what the "31-bit" name in the 390 architecture
means. Mostly it is just Linux with a funny looking main machine
console, and you can get a kick out of goingcat /proc/cpuinfo :-)

Comments:

  - all the others in the image are high-performance, or claim to be
    (Hercules isn't particularly efficient despite being very solid,
    and besides all the others are implemented in a like-on-like manner
    to maximise performance

  - on the other hand, Hercules implements up to 4CPUs, which the others
    can't, so perhaps people would find this useful for testing. Not
    sure how that fits with the goals for VMoppix. If that matters.

  - anyway, it's fun
