Sun Microsystems heeft vrijdag versie 2.2.4 van VirtualBox uitgebracht. Dit programma kan worden gebruikt om een ander besturingssysteem in een virtuele omgeving te installeren. Op die manier is het bijvoorbeeld mogelijk om applicaties in meerdere omgevingen te testen, zonder dat hiervoor specifieke hardware moet worden aangeschaft. VirtualBox is beschikbaar voor Windows 2000 en hoger, Mac OS X, Linux en Solaris, en kan overweg met een groot aantal gastbesturingssystemen.
De software is in twee versies verkrijgbaar. De volledige versie heeft meer functionaliteit, zoals ondersteuning voor usb-poorten en het remote display-protocol, maar is alleen gratis voor privé-gebruik en voor evaluatiedoeleinden. Deze extra functionaliteit is namelijk closed source en ontbreekt in de andere versie, de opensource-uitvoering. Versie 2.2.4 is een zogenaamde maintenance release en bevat voornamelijk veranderingen die een gunstige invloed op zowel de stabiliteit als performance hebben:
