Oracle VM Virtualbox 6.1.20


Oracle VM Virtualbox 6.1.20

Virtualbox est un virtualisateur de systèmes d'exploitation (Windows, Linux/Unix, MacOS) initialement créé par la société Innotek pour être le concurrent direct à VMware Workstation. Ayant l’avantage d'être gratuit (et même disponible en version open-source il fût un temps) il a très vite trouvé son public...

Puis Innotek a été racheté par Sun Microsystems qui, lui-même, a été racheté par Oracle. Ce dernier a modifié la licence d'utilisation pour en faire un logiciel un peu plus fermé qu'à son origine.
