When you deploy multiple virtual RDSH Servers on a Hyper-C cluster you want in most cases some control in the placement of these servers. If you have a two-server RDS Farm you don't want those two nodes to be running on the same Hyper-V Node.
Now it is possible to define anti-affinity for clustergroups. You can create an anti-affinity object called NLBCLuster1 and try to prevent running both RDSH server on the same Hyper-V node by running the following commands:
Cluster.exe group "RDSH01" /prop AntiAffinityClassNames="NLBCluster1"
Cluster.exe group "RDSH02" /prop AntiAffinityClassNames="NLBCluster1"
The anti-affinity can be overridden in some cases where a cluster with reduced capacity needs to keep the VM's running.
