I have a series of screen casts (here) that talk about setting up Hyper-V, but I wanted to let you know that we just released a new Hyper-V: Live Migration Network Configuration Guide here.  I wish I would have had this when I was building out my demos.  This guide does a good job of detailing the different scenarios that are supported and those that are not recommended.  One of the things I did that is different from this guide is that I dedicated two of my four network adapters to my iSCSI connection and I did not dedicate a network connection just for Live Migration.  I like the idea of dedicating a network for Live Migration, I chose to use the two iSCSI NICs and leverage MPIO.  If I was in a production environment, I would lean towards dedicating a network adapter for Live Migration instead.  Or, better yet, I’d consider adding a fifth network adapter so I could do it all. 

It all comes down to where you expect your loads and bottlenecks to occur.  While it is ideal to have a dedicated network for Live Migration, if you don’t, the server will just leverage one of the other network adapters to handle the task. 

I hope this guide helps.
