Ce programme permet d’émuler un PC sous plusieurs OS. Il tourne sous Windows ou sous Linux. Il permet de faire tourner des machines virtuelles sous différents OS (Windows de tout type, Linux, FreeBSD OS/2 etc.), il est également open source et gratuit (pour les particuliers). Les solutions de virtualisation existante étant soit très cher pour le particulier soit incomplète au niveau du support des systèmes, VirtualBox propose une alternative à Vmware et VirtualPC et il s’en sort plus que bien.
