Dobrica Pavlinušić's random unstructured stuff

vz-tools

Suite of perl scripts in spirit of xen-tools but for OpenVZ

Contents

Installation

Install perl dependencies from Debian packages
Install utilities from Debian packages
Checkout source
Check and install perl modules from CPAN

Usage

vz-create.pl
vz-optimize.pl
vz-clone.pl

Source

Installation

Install perl 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.

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

Install utilities from Debian packages

sudo apt-get install host

Checkout source

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

Check and install perl modules from CPAN

cd vz-tools
perl Makefile.PL
make

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

This is quick hand-on overview of commands to get you started.

All commands must be started with root priviledges

vz-create.pl

This will perform following steps:

Create new virtual machine bootstraped using debootstrap
Change root password
Create single user
Make small custimization like installing vim and apt-iselect

All commands will be echoed on screen, even passwords. However, if you want to learn steps in creating OpenVZ VE, this is very helpful.

To run interactive session which asks questions use:

./vz-create.pl

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

./vz-create.pl my-new-ve.exmple.com

or by specifing IP adress

./vz-create.pl 192.168.42.42

vz-optimize.pl

vz-clone.pl

root@black:~/vz-tools# time ./vz-clone.pl create 1001
Clone VE 1001 -> 101001

vzquota : (warning) Quota is running, so data reported from quota file may not reflect current values

Please review config file: /etc/vz/conf/101001.conf
Add NAT for new VE with: iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
Start clone of 1001 with: vzctl start 101001
