Yep, and that's excellent progress. As soon as the stock rawhide kernel
makes its first move to 2.6.27, I plan to build a new kernel-xen based
on that.

What we're discussing currently, though, is whether at that point we
should immediately progress with the plan of merging kernel-xen back
into the stock kernel so that you boot the same pv_ops enabled kernel
for Xen DomU and bare-metal.

If it looks like the Dom0 work is making progress, we might hold off on
doing that until Dom0 is upstream. Personally, I can't see Dom0 being in
shape for F10 and so we should proceed with completing the DomU work.

Cheers,
Mark.
