With the latest errata we pushed to FC5, the Xen stacks & kernels on both
FC5 and FC6 are practically identical[1] - they're both running 2.6.18 kernels
with Xen 3.0.3  hypervisor & kernel & userspace bits. So in terms of guest
OS compatability, stability,performance, etc you shouldn't see any difference
between Xen in FC5 & FC6 (assuming both a fully yum update'd). Thus I'd
recommend FC6 since you'll get a longer lifetime before needing to do another
major upgrade.

Regards,
Dan.

[1] In fact FC5 is currently a couple of changesets ahead of FC6, but we'll
    have an errata for FC6 to update this soon...
