I was wondering about that. It looks like
Documentation/virtual/kvm/api.txt might cover some of that already in
section 5, but it doesn't look complete...

Also, could I get a 00-INDEX file for this directory explaining what
these individual files are? I think "api.txt" is supposed to be
host-side API for controlling a guest VM (from userspace via ioctls,
looks like), and hypercalls.txt is guest-side API for poking the host.
How someone would write host-side code that _responds_ to a hypercall, I
have no idea.  (It goes in the host kernel?)

Either it's "mere aggregation", or a license violation.  Pick one.
