Citrix has released a whitepaper on how to Configuring Key Management System Licensing for Office2010 in Different Scenarios.
The purpose of this document is to help an administrator configure Provisioning Services 5.6 SP1 (PVS) target Devices that are using Microsoft Key Management Server (KMS) in the best way to fit their environment. KMS can be configured on a vDisk Image with the help of PVS to apply volume licenses for Microsoft Server 2008, Microsoft Server 2008R2, Windows 7 and Windows Vista, as well as Office 2010.
In PVS the option for KMS can be easily configured while building vDisk’s with the Imaging Wizard; alternatively it can be configured at any time using the Console or MCLI/Powershell command-line interfaces
The Product Administrator’s Guide, Section “Managing Microsoft KMS Volume Licensing” provides further details on KMS configuration for a PVS vDisk.
