What I'd like to see is some documentation describing the difference
between hiding PCI devices in Xen2 and Xen3 and how to upgrade from Xen2
to Xen3 on a host which hides PCI devices in dom0.

I have a firewall/router which uses Xen2 at the moment and I'd like to
be able to upgrade it to Xen3. However whenever I've tried to set up a
Xen3 box on the bench to hide PCI devices so far it has not even come
close to working...
