Text replacement - "<google>BUY_HYPERV</google>" to "<htmlet>hyperv</htmlet>"
<htmlet>hyperv</htmlet> Microsoft Hyper-V is included as a standard feature of the 64-bit version Windows Server 2008 Standard, Enterprise and Datacenter editions. In addition, Hyper-V is available in both the full and core varients variants of these platforms. The Hyper-V role is not, however, installed and activated by default. The objective of this chapter, therefore, is to provide an overview of the steps involved in installing the Hyper-V role on a Windows Server 2008 system.
== System Requirements ==
The remainder of this chapter assumes that a 64-bit edition of Windows Server 2008 is installed and running on a system with appropriate hardware to support hypervisor based virtualization. Detailed information on these requirements within the context of Hyper-V based virtualization are is outlined in the chapter entitled [[Hyper-V System Requirements]].
== Installing the Hyper-V Role from the Command Prompt ==
As previously mentioned, Hyper-V is bundled by default with the 64-bit version of Windows Server 2008 Standard, Enterprise and Datacenter editions. Before it can be used, however, the Hyper-V role must be installed. This process is achieved using either the Server Manager tool, or via the command-prompt. To perform the installation at the command line, open a command prompt window with elevated privileges (right click on the command prompt icon in the Start menu and select ''Run as administrator'' from the resulting menu) and enter the following command:
<pre>
Select the Hyper-V role and click ''Next'' to proceed. The next screen will provide information about Hyper-V and its associated hardware requirements. After reading this information, click ''Next'' to display the ''Create Virtual Networks'' screen.
In order to communicate with the external network to which the host server is connected, virtual machines need to be able to use a physical network adapter installed on the host computer system. Hyper-V controls this access by creating one or more ''virtual networks'' to which virtual machines are connected. In terms of access to the external network, there is a one to one correlation between virtual networks and physical network adapters installed into the host computer. Multiple virtual networks may not share the same physical network adapter. For additional information on this topic, refer to the chapter entitled [[Understanding and Configuring Hyper-V Virtual Networks]]. This stage of the Hyper-V installation process provides a list of network adapters detected on the host system and provides the option to select the devices for which virtual networks are to be created:
== Verifying the Hyper-V Installation ==
After the installation is complete Hyper-V should be installed and ready for use. To confirm that Hyper-V is installed, open the ''Hyper-V Manager'' manager (''Start->Administration Tools->Hyper-V Manager'').
To begin creating Hyper-V virtual machines, refer to the chapter entitled [[Creating Hyper-V Virtual Machines]].
To perform the removal using Server Manager, select ''Roles'' from the left hand panel of the Server Manager interface and click on ''Remove Roles'' to invoke the ''Remove Roles Wizard''. Deselect the ''Hyper-V'' option from the list of server roles and click ''Next''. Review the information on the ''Confirmation'' screen and click ''Remove'' to perform the removal. It is typically necessary to restart the system to complete the Hyper-V removal process.
