Interesting link, and I will need it in the future, however my first hurdle is enumerating and then mapping the PCI device into my PV domain. I am reading through the Linux kernel initialisation at the moment to see how it gains access to PCI devices. I can see the PCI device references in the Xenstore, but am still working out how to go from that data to an available PCI device in the PV domain.
