I gave a talk on this at LCA, and have been lax in getting my slides online.

If you are talking about the ARCH=um business, UML will always be a
different compile target.
However, the rest of that will be true (with some crossed fingers on

UML will look exactly the same as it does now, and will provide all
the same functionality in pretty much the same way. KVM, plus a
yet-to-be-written userspace controller, together will handle the VT
