The situation is pretty much like this: - Upstream vendor (Xensource) only develops 2.6.18 Xen dom0/domU kernel atm. - paravirt_ops (pv_ops) Xen support in vanilla (v2.6.24+) Linux kernels is currently domU only. Also it's 32bit PAE only, no 64bit yet. Other features are missing too (compared to xensource 2.6.18 xen kernel). - Xen kernel features from 2.6.18 are being ported and added slowly to 2.6.2x pv_ops kernels but it takes time and effort to get them ported and accepted upstream (by linus). Currently Jeremy Fitzhardinge (from Xensource) is doing this work. I think currently he's working on getting 64bit domU support ready/integrated. - Redhat/Fedora has done some pv_ops xen dom0 support work, but it's not ready yet and it hasn't had much progress lately.. unfortunately. - 2.6.22 and 2.6.24 (non pv_ops) kernels with forward ported patches from 2.6.18 are a real pain for kernel maintainers.. - Fedora decided to drop dom0 xen kernel for Fedora 9. Fedora 9 only ships with xen pv_ops domU kernel. They're planning to add dom0 support back for Fedora 10 if/when (pv_ops) dom0 support is included in the upstream vanilla (linus) kernel.
