Chapter 3. Installing XenServer and XenCenter

This chapter steps through installing the XenServer host software on physical servers, installing XenCenter on Windows workstations and connecting them to form the infrastructure for creating and running virtual machines (VMs).

After guiding you through installation, this chapter describes a selection of common installation and deployment scenarios.

3.1. Installation Media and Methods

The XenServer host consists of a Xen-enabled Linux operating system, a management agent, VM templates, and a local storage repository reserved for VMs. The XenServer host must be installed on a dedicated 64-bit x86 server.

Note:

Do not install any other operating system in a dual-boot configuration with the XenServer host; this is an unsupported configuration.

Installation Media

Installers for both the XenServer host and XenCenter are located on the installation media. The installation media also includes the Readme First, which provides descriptions of and links to helpful resources, including product documentation for XenServer and XenServer components.

Installation Methods

There are three methods by which to install the XenServer host:

•From a CD

You can download the installer (ISO file format) and burn it to a CD. To download the installer, visit www.citrix.com/xenserver.

The main XenServer installation file contains the basic packages required to set up XenServer on your host and install XenCenter on your Windows computer, in conjunction with the desired Windows installation media.

•Set up a network-accessible TFTP server to boot using PXE

For details about setting up an TFTP server for PXE-booting the installer, see Appendix C, PXE Boot Installations.

•Install XenServer to a remote disk on a SAN to enable boot from SAN For details, see Appendix B, Boot From SAN Environments.

Supplemental Packs

You can install any required supplemental pack after installing XenServer. To do so, mount the appropriate installation media on the XenServer host, and then run the script install.sh, located in the root directory of the CD.

Upgrades

The installer presents the option to upgrade if it detects a previously installed version of XenServer. The upgrade process follows the first-time installation process, but several setup steps are bypassed. The existing settings are retained, including networking configuration, system time and so on.
