Templates Overview 
Non-base OS EZ template sets should have their own names and are created by appending a 
random identifier to the base OS EZ template name. For example, if you wish your Container to 
run Red Hat Enterprise Linux 5 and to function as a Linux-based server only, you can create the 
redhat-el5-x86-server OS EZ template set and include only those packages in it that are 
needed for performing main server tasks. So, you can specify packages to be used for setting 
up file and print sharing and exclude all the packages for graphical interfaces (GNOME and 
KDE). 
Parallels Virtuozzo Containers provides you with a vzpkg tool allowing you to automatically locate 
and obtain the correct packages for your EZ templates from package repositories. The packages 
are downloaded from the repository and installed on the Hardware Node in one of the following 
cases: 
•  when creating a cache for an OS EZ template 
•  when updating an existing OS EZ template cache (if there are new packages available in the 
repository) 
•  when adding an application EZ template or package to the first Container 
•  when updating EZ templates or software packages inside a destination Container 
Note: Detailed information on how to manage software package repositories is provided in the Setting 
Up Repositories for EZ Templates section (p. 27).
