    That's actually what I was talking about - my comparison to what IBM's
    done may have been a bad example since, as you say, they've virtualized
    the hardware in true IBM (shades of VM) fashion. I think that's
    actually overkill for many usage scenarios since all you really want is
    the ability to run an "instance" of the OS which allows for all the
    user-visible configuration knobs to be changed and the appropriate
    user-visible resource limits to be enforced independently. Essentially
    a jail where it's literally impossible to tell that you're not the only
    "OS" on the machine or to affect a user or resource running on another
    instance.
