Dom0 xen support in Fedora 15?

[M A Young]

I am trying to work out whether it is practical to propose Dom0 xen support as 
a feature for Fedora 15.

The current situation is that patches to allow a kernel to boot as a xen 
Domain 0 are in 2.6.37 but they aren't enough to run a reasonable xen 
guest system from it. The xen developers are aiming to get enough drivers 
accepted in 2.6.38 so that you can run at least basic guest machines.

Given the roughly 3 month kernel release cycle, I would expect Fedora 15 
to ship with a 2.6.37.x kernel, with 2.6.38 coming out at around the time 
of the Fedora 15 release but too late for it to be included, and that 
Fedora 15 will move to 2.6.38 at some later point. Thus Fedora 15 should 
be usable as a xen Domain 0 at some point in its life cycle.

However for xen dom0 support to be a Fedora 15 feature we would really 
need to have the appropriate drivers in the kernel when Fedora 15 ships, 
so my main question is how likely is it that backported xen drivers would 
be accepted into the Fedora kernel? I would also be interested in any 
other comments on this proposal.
