Hyper-V virtualization requirements (SharePoint Server 2010)
This article provides hardware and software requirements for using hardware-based virtualization. Although Windows Server 2008 Hyper-V technology is the focal point of this document, the basic hardware requirements for enabling hardware-based virtualization also apply to third-party virtualization technologies that are certified by Microsoft.
The requirements for hardware-based virtualization are as follows:
Hardware-assisted virtualization, which is available in processors that include a virtualization option—specifically processors with Intel Virtualization Technology (Intel VT) or AMD Virtualization (AMD-V) technology.
Hardware-enforced Data Execution Prevention (DEP) is available and enabled.
You can use one of the following tools to determine if the processor on an existing server supports Hyper-V:
One of the following Microsoft products is required for Hyper-V:
Windows Server 2008 (all editions of Windows Server 2008, except for Windows Server 2008 for Itanium-Based Systems, Windows Web Server 2008, and Windows Server 2008 Foundation)
Microsoft Hyper-V Server 2008
Windows Server 2008 R2 (all editions of Windows Server 2008 R2, except for Windows Server 2008 R2 for Itanium-Based Systems, Windows Web Server 2008 R2, and Windows Server 2008 R2 Foundation)
Hyper-V Server R2
We recommend Windows Server 2008 R2 for virtualization servers because of the many improvements introduced for Hyper-V, such as:
Live migration to move a running virtual machine from one cluster node to another
Significant gains in performance and scalability
Enhanced processor support
Enhanced virtual machine storage
Enhanced networking support
