A couple of years ago I've created a Linux-based virtual machine (VM) for Web/software demos that require a server component (web, db, etc.). It was very easy to carry the VM everywhere and demonstrate the results running an entire client-server environment on my laptop.

Based on this experience, I've created a VM for Drupal site and module developers. (There were some similar systems but they were based on different OS distros and/or they seemed to be a bit abandoned.)

My CentOS based Drupal VM (Drucent) contains the necessary software components for running Drupal sites (for development, archiving or demo purposes), there are several Drupal modules (tested more than a hundred) to choose from, and the Eclipse sw devel environment for module developers.
