VMs are associated, via their settings, with a Virtual Network. A Virtual Network is associated (via Virtual Network Manager—from host computer node in Hyper-V Manager select it on the contex menu) with a specific NIC.

Then disable the host (i.e. parent partition) from using that NIC.

(This is the suggested configuration: avoiding both parent and guests all using the same NICs.)

Thank You. I just did it and it wokrs perfectly.. – user56979 Oct 13 '10 at 13:24
how do you disable the host from using the NIC for Hyper-V Server (not win2k8)? I didn't see anything in Hyper-V Manager. Is this a command-line operation? – kenwarner Oct 22 '10 at 1:53
@qntmfred: I think it would be just unbinding protocols from the NIC in the parent partition, but--as this is best practice--would start with the online H-V documentation. – Richard Oct 22 '10 at 21:16
