June 16th, 2015 -- New Openstack-Opendaylight laboratory scenarios available: https://goo.gl/JpxCnB. Designed to explore an OpenStack environment running OpenDaylight as the network management provider. Prepared by Raúl Álvarez Pinilla as a result of his Master's Thesis.
June 16th, 2015 -- New LXC root filesystems based on Ubuntu 15.04 available (32 and 64 bits). Download it from here or using "vnx_download_rootfs" command.
June 10th, 2015 -- New root filesystems based on REMnux: A Linux Toolkit for Reverse-Engineering and Analyzing Malware. Download it from here or using "vnx_download_rootfs" command. Use simple_remnux.xml example scenario to test it.
June 6th, 2015 -- New interesting VNX scenario available: a security lab designed to allow 16 student groups to work together configuring firewalls and using security related tools and distributions.
April 25th, 2015 -- New root filesystems based on Ubuntu 15.04 available (server and lubuntu in 32 and 64 bits versions). Download it from here or using "vnx_download_rootfs" command.
March 16th, 2015 -- Latest VNX versions include bash completion capabilities. Just use tab key to see the command line options available and help completiting option values.
March 6th, 2015 -- New root filesystems based on Kali 1.1.0 available (32 and 64 bits versions). Download it from here or using "vnx_download_rootfs" command. Update VNX version with 'vnx_update' command before using it.

August 27th, 2014 -- New functionality implemented to specify the position, size and desktop number where the VM console windows are shown by using .cvnx files. See more information here.
June 21th, 2014 -- New root filesystem based on Kali Linux (old Backtrack) available (32 and 64 bits versions). Download it from here or using "vnx_download_rootfs" command. Use simple_kali.xml and simple_kali64.xml examples to test them (now the examples include direct Internet connection). Update VNX to latest version to use them.

October 17th, 2012 -- New root filesystem added based on CAINE (Computer Aided INvestigative Environment) Ubuntu distribution. Download it from here or using "vnx_download_rootfs" command. A new simple_caine.xml example has been added to latest VNX distribution to easy testing it.
June 19th, 2012 -- A new updated Debian root filesystem has been created, as well as a new UML kernel (ver 3.3.8) to work with it. See how to download and install them and the recipes followed for their creation: rootfs and kernel. To create the kernel, the traditional UML exec extension kernel patch has been updated to work with kernel 3.3.8. You can find the new kernel patch here
May 31th, 2012 -- New beta version of VNX (2.0b.2243) released including distributed deployment capabilities (EDIV). See the documentation for more information.
VNX is a general purpose open-source virtualization tool designed to help building virtual network testbeds automatically. It allows the definition and automatic deployment of 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:
- VNX uses libvirt to interact with the virtualization capabilities of the host, allowing the use of most of the virtualization platforms available for Linux (KVM, Xen, etc)
- Integrates Dynamips and Olive router virtualization platforms to allow limited emulation of CISCO and Juniper routers
- Integrates also Linux Containers (LXC) support
- Individual management of virtual machines
- Autoconfiguration and command execution capabilities for several operating systems: Linux, FreeBSD and Windows (XP and 7)
- Integration of Openvswitch with support for VLAN configuration, inter-switches connections and SDN parameter configuration (controller ip address, mode, Openflow version, etc.).
VNX has been developed with the help and support of several people and companies. See the VNX team page for details.
