Note: Please, be aware that this is beta software. It has been developed and mainly tested over Suse 8.1/8.2/9.0/9.1/9.3/10.0 Linux distribution, although it should work (maybe with minor modifications) over other Linux distributions (successfull tests over Red Hat 7.3/8.0/9.0 and FC4, Slackware 8.1, Mandrake 10.0 and Debian 3.0/3.1/4.0/5.0 have been already done). Let us know if you test VNUML over other distributions to include the information here.

deb binary/

To install the packages:

  • VNUML. You can install VNUML and the UML kernel using APT (details here.):
 apt-get update
 apt-get install vnuml

Additional downloads


VNUML Live CD/DVDs are hosted at SourceForge. Here is the complete list.

Latest version is VNUML Live 2.1 (30/04/2007). You can have a look at the README file.

IMPORTANT NOTE: if you plan to install VNUML-Live-DVD on your hard disk, take into account the user creation known issue described here.

To start VNUML Live DVD from inside VMware, you can use this file.

VNUML Virtual Appliances

A new VNUML Virtual appliance has been contributed by Borja Garnelo and Héctor Rodríguez from the Universidad de León. It is based on Ubuntu 9.10 and includes VNUML 1.8.9, as well as other utilities like nmap, ethercap, yersinia, wireshark and etherape.

The virtual appliance is in OVF 1.0 format and has been tested over VirtualBox. In theory, as OVF is a standard format, it should be readable by other virtualization suites; however, tests made with VMware converted have failed to load the virtual appliance (even using OVF 0.9 format).

Download: VNUML Virtual Appliance 2.2 rc2. The user "normal" (the vm automatically logins with that user) password is "normalVNUML".

Previous version: VMware based virtual appliance created starting from VNUML-Live-DVD (following the procedure described here).

Download: VNUML Virtual Appliance 2.1. See how to use it

VNUML CoLinux image

We have also created a VNUML coLinux based image. Cooperative Linux (coLinux) is a virtualization software that allows running Linux virtual machines over Windows.

Latest version is: coLinux VNUML image 1.0. See how to install and use it

About VNUML versions and numbering

  • VNUML language (in fact the DTD for the VNUML files) is identified by two version numbers, for example, VNUML DTD 1.2.
  • VNUML parser is identified by three version numbers. The first two numbers refers to the VNUML DTD version the parser works with. For example, 1.2.1 works with VNUML DTD 1.2 files.
  • The first public releases were VNUML DTD 1.2 and 1.2.1.
  • Since 1.8.0, odd-ended versions are stable ones and even-ended versions are testing ones (in fact, even-ended versions are always suffixed like in: 1.8.0test1, 1.8.2beta1, 1.8.2rc1, etc.). See this post for details.
