Hyper-V is Microsoft’s virtualization offering system for x64 systems. Hyper-V will work with x64 editions of Windows Server 2008.

A free stand-alone version of Hyper-V, called "Microsoft Hyper-V Server 2008" was released which is a variant of the Windows Server 2008 Core OS. The free Hyper-V Core version is limited to a command line interface (CLI), where configuration of the actual OS, physical hardware, and software is done using shell commands and scripts.
