Suite of perl scripts in spirit of "xen-tools"<http://www.xen-tools.org/> but for "OpenVZ"<http://openvz.org/>

{toc: }

^ Installation

^^ Install dependencies from Debian packages

This step is optional. If you don't want to use perl modules from packages provided by your distribution, skip this step, and modules will be automatically installed in next one.

.pre
sudo apt-get install libio-prompt-perl libregexp-common-perl libdata-dump-perl
.pre

^^ Checkout source

.pre
svn co svn://svn.rot13.org/vz-tools/trunk vz-tools
.pre

^^ Check and install perl modules from CPAN

.pre
cd vz-tools
perl Makefile.PL
make
.pre

Please note that there is no need to run `make install`

Tools are runnable from current directory. This will probably change in later versions.

^ Usage

^^ vz-create.pl

To run interactive session which asks questions use:

.pre
sudo ./vz-create.pl
.pre

Other alternative is to just enter hostname (defined in `/etc/hosts` for example) or IP address

^^ vz-optimize.pl

^^ vz-clone.pl

.pre
root@black:~/vz-tools# time ./vz-clone.pl create 1001
