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.

Regards.
