xCAT is the bare-metal provisioning tool primarily used within VCL. It has the ability to install physical nodes with an operating system such as; windows Red Hat, CentOS, ESX, SLES on x86 based hardware. This guide will discuss adding support to VCL for kickstart based or diskfull installs.

The template files used by xCAT reside in /opt/xcat/share/xcat/install/<distro>. distro can be rh, centos, fedora, esx, etc. Make sure to have a working template file. There are several examples in either of the distro directories that can used as a starting point. Once you have a working template, proceed to adding to the VCL database.
The name of the template file and the image.name must match. VCL uses this name to check for and properly load using kickstart method. The xcat name will have the .tmpl, for example the vcl image.name entry of rhel5-base25-v0 the template file for xcat will be rhel5-base25-v0.tmpl.
