[...] 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 ;-) Ingo
