Maybe it is not designed tobe evil, but...

it is so complex it is 'hard' to opensource, it is missdesigned,
anyway... so fix the design.

My proposal would be: add open-source hypervisor interface, and keep
it updated for a while. If it is too hard to keep updated, we'll have
to solve it, somehow, but lets not overengineer it now.
