To clarify, I didn't ask to implement anything in KVM or QNX. I asked to 
write the bindings in a way that they are not Xen specific to give a 
chance to for other to re-use them. Yes today KVM and QNX would not use 
them... But I also still don't see why we should actively prevent them 
to use the bindings you come up with...

Cheers,
