So the vanilla/mainline Linux kernel can be used as Xen domU (guest) out-of-the-box. Fedora 10 and Fedora 11 run as Xen domU (guest), using the same/default kernel as baremetal. Xen dom0 (host) is a different thing. pv_ops Xen dom0 support is still under development, and it's not yet in mainline Linux kernel.
