    ugh, PC boards are actually far worse and far more diverse than any
    variances between hypervisors, but i digress.

    anyway, my point stands: the Linux kernel is significantly more
    maintainable and easier to QA if it has only a single 'external'
    hypervisor ABI to worry about - and that might as well be VMI. This is a
    really obvious point, i expected the discussion to center more around
    the specifics of such a move ;-)
