Microsoft Windows Server 2008 Hyper-V Support and Configuration

The purpose of this document is to identify the Dell™ servers supporting the Microsoft® Windows Server® 2008 Hyper-V™ hypervisor and provide steps to configure Dell™ servers for virtualization. It further explains how to enable Hyper-V in Windows Server 2008.
Microsoft Windows Server 2008 64-bit editions will contain a beta version of Hyper-V, Microsoft’s hypervisor-based virtualization software. Hyper-V is available only in 64-bit editions of Windows Server 2008. Hyper-V requires that all processors on the server be 64-bit. Hyper-V also requires that hardware-assisted virtualization—Intel® Virtualization Technology (Intel VT) or AMD Virtualization™ (AMD-V™)—and Data Execution Prevention (NX feature on Intel or XD feature on AMD) be supported by the processors, and these processor features should be enabled in the server BIOS.

Dell will provide limited support for the beta version of Hyper-V included in the Windows Server 2008 64-bit OS installed on Dell servers. This includes adding and removing the Hyper-V role and limited configuration of the role. The Hyper-V beta release is currently supported on the following Dell PowerEdge™ servers:

· PowerEdge 6800*
· PowerEdge 6850*
· PowerEdge 1950
· PowerEdge 2900
· PowerEdge 2950
· PowerEdge 1900
· PowerEdge 1955
· PowerEdge 6950
· PowerEdge SC1435
· PowerEdge 2970
· PowerEdge T105
· PowerEdge R200**
· PowerEdge R900
· PowerEdge M600
· PowerEdge M605

* The PowerEdge 6800 and PowerEdge 6850 supported single-core Intel Xeon® MP processors (Cranford and Potomac) and dual-core Intel Xeon MP (Paxville and Tulsa) processors. However, the Cranford and Potomac processors do not support Intel VT hardware-assisted virtualization. So the PowerEdge 6800 and PowerEdge 6850 must be configured with either Paxville or Tulsa dual-core Intel Xeon processors to be capable of running Hyper-V.

**The PowerEdge R200 server must be configured with Intel Xeon processors to run Hyper-V. This server can also be configured with Intel Celeron®, Intel Pentium® Dual-Core, and Intel Core 2 Duo processors—none of which supports Intel VT hardware-assisted virtualization.

Enabling Hardware Features on Dell PowerEdge Servers

The Hyper-V role is only available in 64-bit Editions of Microsoft Windows Server 2008, thus requiring 64-bit processors. Data Execution Prevention (NX for Intel processors or XD for AMD processors) is a requirement for Hyper-V, and this feature is enabled by default on Dell servers (current server BIOS does not allow this feature to be disabled).

Hyper-V requires hardware-assisted virtualization support in the processors. By default, this feature is disabled on Dell servers and must be enabled in the system BIOS before enabling the Hyper-V role. The feature can be enabled by pressing F2 at the POST screen to go into the server BIOS Setup and navigating to the CPU Information page as seen below:

Enabling the Hyper-V Role on Microsoft Windows Server 2008
To install the Hyper-V role on a full installation of Windows Server 2008, follow these steps:

1. Ensure that the required hardware features are enabled in the server BIOS.
2. Log on to the Windows Server 2008 64-bit Edition OS using an account with administrator rights.
3. Start Server Manager by using Start | Administrative Tools | Server Manager.
4. From Server Manager, click Add Roles to launch the Add Roles wizard.
5. Choose the Hyper-V role (see screenshot below)
6. Follow the on-screen instructions of the wizard until the Create Virtual Networks page is reached.
7. To allow virtual machines to communicate on the network, at least one virtual network bound to one physical network adapter must be created. Virtual networks can also be created, modified, and deleted at any time using the Virtual Network Manager. It is considered a best practice to have at least one physical network adapter that does not have a virtual network associated with it to be used for host server management.
8. Continue through the rest of the pages of the wizard.
9. Restart the system when prompted at the end of the Add Roles wizard.

A Hyper-V Manager MMC console may be used either locally or remotely to manage the virtual environment on this server.

To install the Hyper-V role on a Server Core installation of Windows Server 2008, the Optional Component Setup tool ocsetup.exe is used by following these steps:

1. Ensure that the required hardware features are enabled in the BIOS.
2. Log on to the Windows Server 2008 64-bit Edition OS using an account with administrator rights.
3. From the command prompt type the following command:

start /w ocsetup Microsoft-Hyper-V

4. Reboot when prompted.

Now a remote Hyper-V Manager MMC console may be used to create and manage virtual machines on this Server Core server.
