Télécharger Oracle VM VirtualBox 4.0.2 pour tous systèmes

Et voilà une toute nouvelle version pour le virtualisateur de systèmes d’exploitation d’Oracle alias Virtualbox qui arrive dans une version majeure… la 4.0.

Au sommaire des nouveautés de cette version on pourra noter la réorganisation complète du logiciel. Tout d’abord, le logiciel principal s’appelle Virtualbox Manager et n’offre plus par défaut le support des ports USB 2.0, pour cela il faut télécharger (gratuitement) l’Extension Pack qui ajoute donc le support des ports USB 2.0, du RDP et du boot PXE pour les cartes Intel.

Changement également au niveau l’interface du logiciel qui affiche désormais une miniature du système d’exploitation en cours de fonctionnement, la possibilité de créer un raccourci .vbox pour pouvoir démarrer directement une machine virtuelle en double-cliquant sur son icône, la liste des systèmes d’exploitation peut être triée et la suppression de celles-ci ne laisse plus aucune trace sur le disque dur (suppression des disques et images)

Virtualbox peut maintenant gérer 1,5 à 2 Go de RAM sur les machines 32bits, inclus de nouvelles référence de matériel virtuels, améliore l’exportation vers les fichiers OVF et permet de contrôler l’utilisation des ressources utilisées par la machine virtuelle (processeurs, lecture/écriture disque dur) sans oublier naturellement toutes les corrections de bugs qui sont naturellement listés dans le changelog complet ci-dessous :
