Managing EZ Templates
Managing Default Repositories
When you install an OS EZ template on the Node, it is preconfigured to use one or several package
repositories storing Linux OS vendor's file sources. The path to the repositories for most OS EZ
templates and their application EZ templates is automatically set during the EZ template installation
in the mirrorlist or repositories files located in the
/vz/template/<os_name>/<os_version>/<arch>/config/os/default directory.
Thus, you do not have to perform any additional operations to start using an installed OS EZ
template (i.e. cache it and create Containers on its basis). The only requirement your system must
meet is to have an active Internet connection to access the servers where the preconfigured
repositories are located.
Let us assume that you want to use the 32-bit version of Fedora 16 to base your Containers on. To
do this, you install the fedora-core-16-x86-tmpl-4.7.0-3.noarch.rpm EZ template on
the Node:
# vzpkg install template fedora-core-16-x86-tmpl-4.7.0-3.noarch.rpm
Preparing... ############################## [100%]
1:fedora-core-16-x86-tmpl ############################## [100%]
After the OS EZ template has been successfully installed, you can explore the default repositories
for Fedora 16 in the /vz/template/fedora/16/x86/config/os/default/mirrorlist
file. For example:
# cat /vz/template/fedora/16/x86/config/os/default/mirrorlist
$SW_SERVER/download/mirrors/fedora-core-16
$SW_SERVER/download/mirrors/updates-released-fc16
http://mirrors.fedoraproject.org/mirrorlist?repo=fedora-16&arch=i386
http://mirrors.fedoraproject.org/mirrorlist?repo=updates-released-f16&arch=i386
This file lists the repositories set to handle the Fedora 16 OS EZ template:
• Repositories on the Parallels web server are defined in the first two lines. $SW_SERVER denotes
the string whose value is specified in the /vz/template/conf/vztt/url.map file. In our
case, this string is the URL of the Parallels web server. The repositories on the Parallels web
server keep a number of software packages needed for the correct operation of the fedora-
core-16-x86 template. Along with $SW_SERVER, the url.map file contains the list of URLs
for all Linux distributions supported by Parallels Virtuozzo Containers and having official
repositories.
• Repositories on the Fedora web server are defined in the third and fourth lines. These
repositories store all RPM packages for the Fedora 16 distribution.
The priority according to which software packages are downloaded from the specified servers is
determined by the repositories order in the mirrorlist file. So in the example above, RPM
packages from the Parallels web server are downloaded first and, after that, all the packages from
the Fedora server.
