Hyper-V Installation Prerequisites

Applies To: Windows Server 2008 R2

Hyper-V requires specific hardware. You can identify systems that support the x64 architecture and Hyper-V by searching the Windows Server catalog for Hyper-V as an additional qualification. The Windows Server catalog is available at the Microsoft Web site (

To install and use the Hyper-V role, you need the following:

  • An x64-based processor. Hyper-V is available in x64-based versions of Windows Server 2008—specifically, the x64-based versions of Windows Server 2008 Standard, Windows Server 2008 Enterprise, and Windows Server 2008 Datacenter.

  • Hardware-assisted virtualization. This is available in processors that include a virtualization option—specifically, Intel Virtualization Technology (Intel VT) or AMD Virtualization (AMD-V).

  • Hardware-enforced Data Execution Prevention (DEP) must be available and be enabled. Specifically, you must enable the Intel XD bit (execute disable bit) or AMD NX bit (no execute bit).

Additional considerations

  • The settings for hardware-assisted virtualization and hardware-enforced DEP are available in the BIOS. However, the names of the settings may differ from the names identified above. For more information about whether a specific processor model supports Hyper-V, check with the manufacturer of the computer.

  • If you modify the settings for hardware-assisted virtualization or hardware-enforced DEP, you may need to turn off the power to the computer and then turn it back on. Restarting the computer may not apply the changes to the settings.
