There has been no pcifront in recent Fedora kernels, you'll have to
stick with older centOS kernels. or wait until pv_ops domU has landed
(so 2.6.31 at the earliest) *and* the pcifront has been re-implemented
(not sure if anyone other than Jeremy has this in their sights)
Jeremy's git tree has pv_ops pcifront now.
<whisper> or look at ubuntu which I think has forward ported
the old
non-pv_ops xen to more recent kernels </whisper>
Ubuntu's ports are known to be a bit buggy.. I wouldn't recommend those.
Novell/opensuse forward-ports are better.. they're shipping those patches
with SLES11 (Suse Linux Enterprise 11) and with OpenSUSE kernels.
Patches exist up to 2.6.31 currently.

Those patches also work for domU, not only dom0.
