Not a chance unless you are a very hardcore kernel hacker :-) The Xen code is
very intrusive into the heart of the kernel, so updating it to newer kernel
versions is non-trivial. For Fedora we have a guy who works *fulltime*
just doing forward ports of Xen to newer upstream kernel trees & even then
we're typically 4-6 weeks behind upstream releases.

We just released a 2.6.20 + Xen 3.0.3 based kernel to FC6 updates-testing
if that's any use:

http://download.fedora.redhat.com/pub/fedora/linux/core/updates/testing/6/

Work is underway to port it to 2.6.21 as well, but I can't make any promises
for when that'll be released.

Meanwhile F7 is on 2.6.20 + 3.0.4, but this is not as stable as the FC6 3.0.3
based Xen tree is yet. By the time it is released in a couple of months F7
will probably be on 3.0.4 + 2.6.21, although if 3.0.5 comes out in the next
week or so we might skip 3.0.4 and go straight to 3.0.5 for F7.

Regards,
Dan.
