Installing Windows VMs
XenServer allows you to install Windows 2000 SP4, Windows Server 2003 (32-/64- bit), Windows Server
2008, Windows XP SP2/3, Windows Vista and Windows 7 as a VM. Installing Windows VMs on a XenServer
host requires hardware virtualization support (Intel VT or AMD-V).
The process of installing a Windows VM can be broken down into two main steps:
• installing the Windows operating system
• installing the paravirtualized device drivers known as the Citrix Tools for Virtual Machines
Windows VMs are installed by cloning an appropriate template using either XenCenter or the CLI. The
templates for individual guests have predefined platform flags set which define the configuration of the
virtual hardware. For example, all Windows VMs are installed with the ACPI Hardware Abstraction Layer
(HAL) mode enabled. If you subsequently change one of these VMs to have multiple virtual CPUs, Windows
automatically switches the HAL to multi-processor mode.
The available Windows templates are:
• Windows Server 2008 (x86), optimized for Citrix XenApp
