One more though: it is probably a good idea to introduce selftests for
/dev/mshv (similar to KVM's selftests in
/tools/testing/selftests/kvm). Selftests don't really need a stable ABI
as they live in the same linux.git and can be updated in the same patch
series which changes /dev/mshv behavior. Selftests are very useful for
checking there are no regressions, especially in the situation when
there's no publicly available userspace for /dev/mshv.

I think this can wait until we merge the first implementation in tree.
There are still a lot of moving parts. Our (currently limited) internal
test cases need more cleaning up before they are ready. I certainly
don't want to distract Nuno from getting the foundation right.

I'm absolutely fine with this approach, selftests are a nice add-on, not
a requirement for the initial implementation. Also, to make them more
useful to mere mortals, a doc on how to run Linux as root Hyper-V
partition would come handy)
