Microsoft Hyper-V Maximum Supported Configurations

Via Nick MacKechnie's Blog:

"Windows Server 2008 Hyper-V, hypervisor-based server virtualization technology, allows you to make the best use of your server hardware investments by consolidating multiple server workloads as separate virtual machines (VMs) running on a single physical machine. With Hyper-V, you can also efficiently run multiple different operating systems concurrently, on a single server, and fully leverage the power of x64 computing.

When you’re planning a virtualization infrastructure with Hyper-V, please be sure to stay within the supported limits below. In addition, the limits discussed in this document are highly dependent on the underlying hardware server configuration.

Operating System Requirements

Windows Server 2008 includes Hyper-V as an available role. Hyper-V is included with:

· Windows Server 2008 Standard Edition (x64)

· Windows Server 2008 Enterprise Edition (x64)

· Windows Server 2008 Datacenter Edition (x64)

Note: That Hyper-V is an x64 Edition only technology and is not available for 32-bit (x86) or Itanium (IA64) editions.

Hardware Requirements

· Hyper-V requires an x64 processor with Hardware-assisted virtualization. This is available in processors that include a virtualization option; specifically, Intel VT or AMD Virtualization.

· Hardware Data Execution Protection (DEP) is also required and must be enabled. Specifically, you must enable Intel XD bit (execute disable bit) or AMD NX bit (no execute bit).

Virtual Machine Architecture Support

· Hyper-V offers support for:

32-bit (x86) operating systems

64-bit (x64) operating systems

Both 32-bit and 64-bit virtual machines can run concurrently.


· Windows Server 2008 Enterprise/Datacenter Editions

System/Host Physical memory support: Up to 1 TB of physical memory

Virtual Machine memory support: Up to 64 GB of memory per virtual machine

· Windows Server 2008 Standard Edition

System/Host Physical memory: Up to 32 GB of physical memory

Virtual machine memory support: Approximately ~ 31.5 GB total used for all running virtual machines..."
