    I have not setup any virtual machines for production work before and had a question about network adapters. If I was going to install Window 2k8 R2 with 2 VMs, would the best thing to do is have a dedicated NIC for each VM and one for the VM Host Server?

    You should have at least one dedicated network card for the Hyper-v Host server and at least one network card for your VMs. You can however have dedicated network cards for your VMs as well

    That is what I was planning on doing.  2nics teamed for the HOST, standard for me, and each VM will have 2nics teamed.

    Thanks for the article.

    Building your system in such a way that you dedicate physical NICs to VMs is possible but rarely necessary. 

    Only in cases where your VMs require the full bandwidth of a single NIC or the bandwidth of combined NICs that are load balanced in this way.  A 'does not play well with other' type of design.

    This assumes that your application can actually handle it and actually saturates the NIC.

    Otherwise VMs sharing physical NICs using virtual switches is fine and normal is most cases.

    I would have to agree with Brian shared virtual network is the norm.
