Do you use a Microsoft supported network setup for Hyper-V Clustering?

Microsoft lists several recommended and supported network configurations. It is very important that you configure your Hyper-V Cluster with one of the supported network types otherwise you will have performance issues once you load up the cluster. Figure: Check you have one of the supported configurations listed on the >Microsoft Hyper-V Live Migration – Network Configuration page (this example has 3 networks) It may work fine initially on a non-supported configuration but when you start loading more Virtual Machines on to the cluster the performance will be degrade dramatically.
