I'm running a pcie tuner in a Xen VM. Need bleeding edge software and io
virtualization.

. Works well once the bleeding is over with. Interesting, but a separate
box would probably be simpler&cheaper.  Main benefit for my private
setup has been all hard-drives in one box, so repurposing for different
usage (mythtv storage or other stuff) is convenient. Disk through-put in
Xen has been kind of sucky, getting better, recent kernel in both host
and guest helps a lot.
