Sadly that's life with Xen. Upstream Xen has basically stopped all kernel

What's this? Xen kernel development has stopped? What does that mean -
is the GPL project dead?
Not at all.
In fact, I'd strongly disagree with Daniel's characterisation that Xen
has "stopped all kernel development" Redhat need to "finish off" the
paravirt_ops port. I've been working on it full time for the last
couple of years, and have done the vast majority of the work needed to
get paravirt_ops working.
Redhat have contributed valuable work in areas like the paravirtual
framebuffer device, and are working on 64-bit and dom0 support. But all
of that is based on the work I've been doing on paravirt-ops
infrastructure itself and the Xen implementation which uses it.
I'm still actively working on pvops/Xen, and currently focusing on
bringing it up to feature parity with the old 2.6.18-xen patches. In
the last few weeks I've implemented balloon support, save/restore and
starting work on pv-hvm driver support.
Meanwhile, open source Xen is also being actively developed by the
original Xen developers and anyone who wishes to contribute.
