Hi,

we just release a guide on how to configure your Network Cards with Hyper-V  http://technet.microsoft.com/en-us/library/ff428137(WS.10).aspx

I had the chance to check this out up front, and if you just don't have plenty of NIC's (>3), the approach to use Quality of Service (QoS), worked out rather nice for me.

Cheers  

Robert
