Linux 2.6.25 contains Xen pv_ops domU support only.
There is currently no dom0 functionality in 2.6.25 kernel.
Redhat/Fedora is working on writing dom0 support for 2.6.25+ kernels, but
it's still a work in progress.
Currently you have to use either the xensource 2.6.18 based dom0 kernel, or
then some of the forward-ported 2.6.2x xen kernels, but those are less stable
than xensource 2.6.18 version.
I think ubuntu 8.04 has some forward port from xensource 2.6.18 to
2.6.24 with dom0 support.
Doing this "forward porting" is a pain in the ass for distro/kernel
developers, so noone is wanting to do it.
That's why Redhat/Fedora decided to step up and continue the pv_ops work for
2.6.25+ and try to get it integrated into vanilla/linus kernel, so no
patching or forward porting would be needed in the future.
Hopefully that helps.
