AVMA lets you install virtual machines on a properly activated Windows server without having to manage product keys for each individual virtual machine, even in disconnected environments. When the KMS host key corresponds to the licensing of HyperV host servers with Datacenter edition, then an unlimited number of virtual machines running under these HyperV hosts can be automatically activated by using the AVMA method. After installing the KMS host role a KMS host key must be installed. This can be either a physical or a virtual server. When it comes to licensing Windows Server via Volume Licensing (SPLA) a KMS host server role must be configured. The Windows Server licensing also includes Software Assurance (SA) for eligibility to Microsoft Support and future updates.

There are many ways in which Windows Server can be licensed. You need to also activate virtual machines which run under a KMS licensed HyperV server or cluster. You need to activate Windows Server using a KMS host key.
