How is Windows HPC Server 2008 licensed?

Windows® HPC Server 2008 is licensed per server. The software is licensed based on the number of instances of server software that you run. You may run, at any one time, one instance of the server software in one physical operating system environment and one instance in one virtual operating system environment on the licensed server.

If you run both permitted instances at the same time, the instance of the server software that is running in the physical operating system environment may only be used to:

  • Run hardware virtualization software
