Welcome to Virtual Network User-Mode-Linux (VNUML) web server
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.
