Citrix Systems 5.6 manual Template parameters

Templates are essentially VMs with the is-a-templateparameter set to true. A template is a "gold image" that contains all the various configuration settings to instantiate a specific VM. XenServer ships with a base set of templates, which range from generic "raw" VMs that can boot an OS vendor installation CD (RHEL, CentOS, SLES, Windows) to complete pre-configured OS instances (the "Demo Linux VM" template). With XenServer you can create VMs, configure them in standard forms for your particular needs, and save a copy of them as templates for future use in VM deployment.

The template objects can be listed with the standard object listing command (xe template-list), and the parameters manipulated with the standard parameter commands. See the section called “Low-level param commands” for details.
