That's part of the problem -- it's not, and it can't be.  It's about the

hypervisor providing a specific service to its guest, and although we

can explain how Linux would use this, there is going to be an

expectation -- especially for Microsoft and Apple -- that other OSes

would use the same interfaces (to the extent they care, obviously.)
