Chapter 1. About this document 1.1. Overview This document is a guide to creating Virtual Machines with XenServer™, the platform virtualization solution from Citrix™. It describes the various methods of getting VMs up and running on XenServer Hosts for each of the supported operating systems. This section summarizes the rest of the guide so that you can find the information you need. The following topics are covered: • general information about creating VMs • creating Windows VMs • creating Linux VMs • updating VMs • Creating and using ISO images of vendor media for installing VMs • Setting up a network repository of vendor media for installing VMs • Troubleshooting problems with VMs 1.2. How this Guide relates to other documentation This document is primarily aimed at system administrators who need to set up deployments of XenServer VMs. Other documentation shipped with this release includes: • XenServer Installation Guide provides a high level overview of XenServer, along with step-by-step in- structions on installing XenServer Hosts and the XenCenter management console; • XenServer Administrator's Guide describes the tasks involved in configuring a XenServer deployment -- how to set up storage, networking and resource pools, and how to administer XenServer Hosts using the xe command line interface (CLI). • XenServer Software Development Kit Guide presents an overview of the XenServer SDK -- a selection of code samples that demonstrate how to write applications that interface with XenServer Hosts. • XenAPI Specification provides a programmer's reference guide to the XenServer API. • Release notes provide a list of known issues that affect this release. 1
