I expect you know this, but just to clarify HVM is independent of the Linux 
domU kernel.  If dom0 and Xen support it then it'll work.

Glad it's a good step for you.

The suspend / resume / migration needs cleaning up, plus I think it conflicts 
with other features (pre-emption?) at the moment.

Hopefully it'll minimise the diff between a fully featured Xenified kernel, 
and the mainline, even if there are still patches required for full 
functionality.  In the long run this ought to make life easier for everyone 
concerned.

Enjoy.  Would be nice to have some success reports (or bug reports if 
appropriate) once you've tried out the new kernels.

Cheers,
Mark
