Managing EZ Templates
Installing vztt-build
The first step in creating a template from scratch is to install the vztt-build package on your
Node. This package contains
• template metafile samples. You use metafile samples as the basis for creating a metafile for
your own template.
• the vzmktmpl utility. You use the vzmktmpl utility to create the template on the basis of your
metafile.
The vztt-build package is located in the /virtuozzo/RPMS/optional directory of your
Parallels Virtuozzo Containers distribution and is not installed by default during the installation. To
install the vztt-build package, use the rpm -i command, for example:
# rpm -i /virtuozzo/RPMS/optional/vztt-build-4.7.0-11.x86_64.rpm
Creating Metafiles
In the second step, you make a metafile, a plain text file having the .metafile extension and
containing a list of parameters for your template. The vzmktmpl utility uses this file when creating
the template.
The following example demonstrates the process of creating a metafile for the x64 version of
CentOS 5. To create the metafile:
1 Create a new text file with an arbitrary name and the.metafile extension (e.g., centos-5-
custom.metafile).
The easiest way to create a new metafile is to copy one of the metafile samples from the
/usr/share/vztt/samples directory and configure it to meet your demands. For example,
you can use the /usr/share/vztt/samples/centos-5-x86_64/metafile file as the
basis for creating your new metafile for CentOS 5.
# cp /usr/share/vztt/samples/centos-5-x86_64/metafile /home/user1
2 Configure the metafile to meet your demands:
a %osname. Specify the name of the Linux distribution for which you are creating the OS EZ
template:
%osname
centos-custom
The specified name will be assigned to the template directory where you will install the
template (e.g., in our case, it will be /vz/template/centos-custom).
b %osver. Specify the version of the Linux distribution for which you are creating the
template:
%osver
5
The specified name will be assigned to the subdirectory that will denote the version of your
Linux distribution (e.g., /vz/template/centos-custom/5).
