Welcome to Virtual Networks over linuX (VNX) web site

VNX is a general purpose open-source virtualization tool designed to help building virtual network testbeds automatically. It allows to define network scenarios made of virtual machines of different types (Linux, Windows, FreeBSD, Olive or Dynamips routers, etc) interconnected following a user-defined topology possibly connected to external networks.

VNX is a useful tool for testing network applications/services over complex testbeds made of virtual nodes and networks, as well as for creating complex network laboratories to allow students to interact with realistic network scenarios. As other similar tools aimed to create virtual network scenarios (like GNS3, NetKit, MLN or Marionnet), VNX provides a way to manage testbeds avoiding the investment and management complexity needed to create them using real equipment.

VNX is made of two main parts: an XML language that allows describing the virtual network scenario (VNX specification language); and the VNX program, that parses the scenario description and builds and manages the virtual scenario over a Linux machine.

VNX comes with a distributed version (EDIV) that allows the deployment of virtual scenarios over clusters of Linux servers, improving the scalability to scenarios made of tenths or even hundreds of virtual machines.


Or


VNX is build on the long experience of a previous tool named VNUML (Virtual Networks over User Mode Linux)


quickly define and test complex network emulation scenarios based on virtual machines running over Linux hosts.


VNX is tool that can be used to emulate general Linux based network scenarios.

VNX History

VNX (Virtualization over X) is the new release of the VNUML tool. VNX brings important new functionalities that overcome the most important limitations VNUML tool has:

  • Integration of new virtualization platforms to allow virtual machines running other operating systems (Windows, FreeBSD, etc) apart from Linux. In this sense:
    • VNX uses libvirt to interact with the virtualization capabilities, allowing the use of most of the virtualization platforms available for Linux (KVM, Xen, etc)
    • Integrates Dynamips to allow limited emulation of CISCO routers
  • Restart of individual virtual machines
  • Autoconfiguration and command execution capabilities for several operating systems: Linux, FreeBSD and Windows (XP and 7).
