An overview of Microsoft licensing models for the server operating system and server applications under virtual environments.
This white paper describes Microsoft licensing models for the server operating systems and server applications under virtual environments. It can help you understand how to use Microsoft server products with virtualization technologies, such as Microsoft Hyper-V technology, Microsoft Virtual Server 2005 R2, or third-party virtualization solutions that are provided by VMWare and Parallels.
Although much of the information in this white paper also applies to licenses that are purchased from channels other than Microsoft Volume Licensing, some differences exist. If you acquired licenses through a means other than a Microsoft Volume Licensing agreement, we recommend that you review the license terms that accompanied your software.
