Paravirtualized pv_ops Xen domU (guest) support is included in the default kernels; 
"kernel-PAE" for 32bit and "kernel" for 64bit Fedora 10.

Fedora 11 will also ship with PV pv_ops Xen domU support included in the default kernels.

There's this bug in F10 which affects 32bit domU installs:
https://bugzilla.redhat.com/show_bug.cgi?id=470905

Also see this tip if you want to install 32bit F10 domUs:
https://www.redhat.com/archives/fedora-xen/2009-March/msg00067.html

F11 (when it's out) should also install out of the box as a Xen PV domU.

Also earlier Fedora versions should work as a domU out of the box.

If you're talking about dom0 (host) then Fedora 8 is currently the latest
Fedora release having Xen dom0 capable kernel. 

dom0 support will be added back to Fedora when pv_ops dom0 support is included in the
vanilla/mainline Linux kernels (merging should happen for Linux 2.6.30).
