Yeah, i'm really just a user and code reviewer of tools/kvm/, in
terms of actual commits i'm barely on the radar compared to the
massive contributions of Pekka, Sasha, Asias, Cyrill and others.

That puzzles me as well.

If tools/kvm/ is really such a bad approach then it will just wither
and die, like one of the thousand stale drivers we have in the kernel
- or like lguest it ends up as a cool hack that didnt quite make it.

Judging by the many contributions tools/kvm/ has already attracted in
its limited form an out of tree project i'd not bet on that outcome
though.

Thanks,
