Hyper-V is a hypervisor-based virtualization platform that Microsoft contains in Windows Server 2008. Unlike Virtual Server R2 (managed technology running on the Windows Server 2003 operating system), Hyper-V runs directly on the system hardware. Hyper-V can be run on a full installation of Windows Server 2008 or on a minimal Server Core installation, at which point it achieves optimal performance with minimal overhead and a relatively small attack su
