VM Groups in Windows Server 2016 Hyper-V

Q. What are VM Groups in Windows Server 2016?

A. VM Groups provide a new way to manage VMs by grouping VMs together that need actions performed on together. There are two types of group:

  • VM Collection Group - A collection of VMs

  • Management Collection Group - A collection of VM Collection Groups and/or other Management Collection Groups

VM Groups must be used when backing up VHD Sets (Shared VHDX) or replicating them with Hyper-V Replica as it enables the necessary orchestration between multiple VMs when performing actions on shared VHDX files. They also provide easy management of multiple VMs when using VM Collection Groups. Below is some example PowerShell to create and use the groups.
