If you have two NICs, where one of them is PCI passthrough and
the other dedicated to the guests, then the second can serve as
netback/netfront.
Thought I wonder if you can have the netback in the guest. This
way you could fiddle with your registers in one domain, and export
a network interface (vif) to the other guests from the domain that
owns the PCI device.
