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)
- 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.
VNX is built over the long experience of a previous tool named VNUML (Virtual Networks over User Mode Linux) and brings important new functionalities that overcome the most important limitations VNUML tool had:
- Integration of new virtualization platforms to allow virtual machines running other operating systems (Windows, FreeBSD, etc) apart from Linux. In this sense:
- Individual management of virtual machines
- Autoconfiguration and command execution capabilities for several operating systems: Linux, FreeBSD and Windows (XP and 7)
VNX has been developed with the help and support of several people and companies. See the VNX team page for details.
VNX Latest News
May 31th, 2012 -- A new beta version of VNX (2.0b.2243) including a (reasonably) stable version of EDIV, the distributed deployment version of VNX that allows the deployment of virtual scenarios over clusters of VNX hosts.
