That was the first thing we started looking at.

It would actually be better technically (since it would use the 
back-channel between PF and VFs rather than needing an explicit virtual 
network link between host/guest) but it would require work in all the 
PF/VF drivers.  We'd need to get support from all the driver maintainers.

The main advantage of doing it in bonding is that we'd only need to 
modify the code in one place.
