Oracle heeft versie 4.3.18 van VirtualBox uitgebracht. VirtualBox kan worden gebruikt om andere besturingssystemen in een virtuele omgeving op een computer te installeren. Op die manier is het mogelijk om verschillende besturingssystemen op dezelfde hardware naast elkaar en tegelijkertijd te gebruiken. VirtualBox is beschikbaar voor Windows XP en hoger, OS X, Linux en Solaris, en is in staat om een groot aantal gastbesturingssystemen te draaien.
In versie 4.3 van VirtualBox is onder meer de complete virtualisatiecode herschreven, wat diverse problemen heeft verholpen en ook verschillende prestatieverbeteringen laat zien. Verder zijn er videocapturing en ondersteuning voor ipv6, kunnen diverse virtuele machines die op dezelfde computer draaien nu via het interne netwerk met elkaar communiceren en is er ondersteuning voor multitouchschermen. Deze tiende update bevat verder nog de volgende verbeteringen:
