Microsoft Hyper-V (formerly codenamed Viridian) is hypervisor-based visualization for Windows Server based x86-64 systems. The beta of Hyper-V shipped some x64 editions of Windows Server 2008 , and the finalized version was released via Windows Update in June 2008 and has since been released as a free stand-alone version (Hyper-V Server 2008 R2). Hyper-V currently exists in two distinct versions: a stand-alone product called Hyper-V Server 2008 R2 and as an integral part of Windows Server 2008 R2.
The first requirement is for a machine which can support a 64-bit operating system. You will need a clean installation of Windows Server 2008 Enterprise Edition (64-bit version) , as Hyper-V will not run within a virtual machine due to the need for hardware-assisted virtualization.
Prior to installing Hyper-V you should take some precautions, namely:
- Back up all data on the system.
- Take an inventory of all virtual machines you will be migrating to the Hyper-V machine, including all of the virtual hardware settings for the virtual machines.
- Back up all virtual hard disks (VHDs) which will be migrated.
- Enable the hardware-assisted virtualization. This is normally found in the computer’s BIOS, and it may be necessary to refer to the documentation or contact for how to enable this.
- Install Windows Server 2008 / or 2008 R2. In this case, we will be using the full installation option (but note that Hyper-V can be also used on a Server Core installation).
- Do not install other roles on the target machine – Hyper-V should be the sole role on the machine that will host virtual machines.
Log in as an administrator and perform the following steps:
Start the Server Manager (Start menu > Administrative Tools > Server Manager).
Under Roles Summary, select Add Roles, then select Hyper-V.
Complete the remainder of the setup wizard. You are not required to allow virtual machines to access network resources, but one network card needs to be selected, so that this can be bound to a virtual switch. You will also be shown a warning if your computer has just a single network adapter; two are network adapters are recommended.
