To make sure that View Composer properly activates Windows Server operating systems on linked-clone RDS hosts, you must use Microsoft volume activation on the parent virtual machine. The volume-activation technology requires a volume license key.
To activate Windows with volume activation, you use Key Management Service (KMS), which requires a KMS license key. See your Microsoft dealer to acquire a volume license key and configure volume activation.
Before you create linked-clone machines with View Composer, you must use volume activation to activate the operating system on the parent virtual machine.
When a linked-clone machine is created, and each time the linked clone is recomposed, the View Composer agent uses the parent virtual machine's KMS server to activate the operating system on the linked clone.
For KMS licensing, View Composer uses the KMS server that is configured to activate the parent virtual machine. The KMS server treats an activated linked clone as a computer with a newly issued license.
