We found out that it's possible to use a pci backend hack to hide a device
from Dom0 and bind it to a specific DomU.

The thing is that this will not fix my problem, as all I need is to the DomU
to see specific data about the network controller. I can't hide this device
from Dom0, or several other things will stop working. :)

I was thinking about writing a module that will assign a fake PCI device
just to provide my software with the information needed, but I was hoping
some expert soul on this list would help me get through with an easier
solution.

Thanks

I can only conform this:
# cat /proc/bus/pci/devices
