How many VMs can Hyper-V support?
In Windows Server 2008 R2, Hyper-V can support up to 384 virtual machines (VMs) as long as the number of virtual processors assigned to those VMs do not exceed 512. These numbers change a bit if you are running Hyper-V in a Failover Cluster. You can only support 64 VMs per node of the cluster. Since all business critical applications and services need to have a fault-tolerant solution, you will more than likely be running your VMs on a Failover Cluster. So, for the production environment, I would say 64 VMs is the limit.
