That makes a lot of sense to me.

I think we better have damn good technical reasons before we encourage a fork
of a subsystem within the kernel. Technical truth is not something we can
'agree to disagree' on, and it is not something we can compromise on really.

Both the host and the guest code is in Linux so adding another variant without
that variant replacing the old one (on the spot or gradually) makes no
technical sense.

Gregory, i'd suggest for you to shape this as a "this and this aspect of KVM
needs to be replaced/fixed" list of items, as suggested by Anthony. In my
experience the KVM folks are very approachable and very reasonable about
addressing technical shortcomings and acting upon feedback (and are happily
accepting code as well) - so to the extent there's room for improvement here
it should be done by shaping KVM, not by forking and rebranding it.
