Updating OS EZ Template Caches
With the release of new updates for the corresponding Linux distribution, the created OS EZ
template cache can become obsolete. Parallels Server Bare Metal allows you to quickly update
your OS EZ template caches using the vzpkg update cache command.
Note: If you are going to update the cache of a commercial OS EZ template (e.g. Red Hat
Enterprise Server 5 or SLES 10), you should first update software packages in the remote
repository used to handle this OS EZ template and then proceed with updating the EZ template
cache. Detailed information on how to manage repositories for commercial Linux distributions
is provided in the Parallels Command Line Reference Guide.
When executed, vzpkg update cache checks the cache directory in the template area (by
default, the template area is located in /vz/template) on the Parallels server and updates all
existing tarballs in this directory. However, you can explicitly indicate the tarball for what OS
EZ template should be updated by specifying the OS EZ template name. For example, to update
the tarball for the fedora-core-8-x86 OS EZ template, you should issue the following
command:
# vzpkg update cache fedora-core-8-x86
Loading "rpm2vzrpm" plugin

base2 100% |=========================| 951 B 00:00
base3 100% |=========================| 951 B 00:00
...
Upon the vzpkg update cache execution, the old tarball is renamed by receiving the -
old suffix (e.g. fedora-core-8-x86.tar.gz-old):
# ls /vz/template/cache
fedora-core-8-x86.tar.gz fedora-core-8-x86.tar.gz-old
You can also pass the -f option to vzpkg update cache to remove an existing tar archive
and create a new one instead of it.
If the vzpkg update cache command does not find a tarball for one or several OS EZ
templates installed on the server, it creates tar archives of the corresponding OS EZ templates
and puts them to the /vz/template/cache directory.
