VNUML Live is a a Gentoo based Live CD that contains the Virtual Network User Mode Linux virtualization tool.

VNUML (Virtual Network User Mode Linux) is an open-source general purpose virtualization tool designed to quickly define and test complex network simulation scenarios based on the great User Mode Linux (UML) virtualization software. It has been initially developed in the context of Euro6IX research project to simulate IPv6 IX scenarios based on Linux and zebra/quagga routing daemons (see our article on IEEE Comms. Magazine). However, it is a useful tool that can be used to simulate general Linux based network scenarios.

VNUML is aimed to help in testing network applications and services over complex testbeds made of several nodes (even tenths) and networks inside one Linux machine, without involving the investment and management complexity needed to create them using real equipment.

VNUML tool is made of two main componets: the VNUML language used for describing simulations in XML; and the interpreter of the language (vnuml command), that builds and manages the simulation, hidding all UML complex details to the user.

In order to easily test VNUML without having to install it in your computer, we have created a VNUML-Live-DVD based on Ubuntu that includes the VNUML tool and most of the examples available on this web.

Below are some useful notes about VNUML-Live-DVD:

Keyboard. Live DVD uses by default the english keymap. You can change to other keymap by pressing F3 key during boot up.

Installation on hard disk. If you plan to install VNUML-Live-DVD on your hard disk using the standard Ubuntu procedure (install button on your desktop), take into account that there is a known problem related to user management: the user you are asked to create during installation process is not created correctly. In fact, after installation is finished and you restart the computer, you won´t be able to login with that user. Use the default user (ubuntu/ubuntu) to access the system and re-create the user through the administration menus.
