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

VNX is build on the long experience of a previos 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. It 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.

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).
