Xen-0 is a __major__ patch, redirecting all ring-0 ops if xen-0 is
enabled. Currently, HVM guests are not waiting on this .. and pv guests
have alternates.

Feeding that patch to LKML in an agreeable way is not going to be easy,
I do not envy that task.. neither does anyone working for Redhat, SUSE
or working on Debian.

Xen (open source) is and always be an integrator's tool box. If you
really , really need a new kernel, grab the Debian/SUSE 2.6.26 and start
sending in bug reports (even better, patches)... otherwise
(unfortunately) you have no other choice but to wait for one of two
possible outcomes:

1 - Xen-0 is accepted in mainline
2 - XenLinux jumps to 2.6.27 (or so).

I completely agree with you, and it is frustrating to make Xen an
offering or a tool that gets past your bosses. If xen-0 does not appear
soon in mainline, I'll be begging for a newer official XenLinux too.

But please, give it a little more time. The patch involved is really
__anything__ but trivial. We're all stuck in the same rut.
