Oracle vient d’annoncer la disponibilité de la version Release Candidate 4.3.0 de son produit de virtualisation VirtualBox. Cette nouvelle version utilise désormais par défaut le nombre maximum de cœurs physiques pour le nombre maximum de CPU virtuels et non plus 1 seul.

D’autres corrections pour nos machines sous Linux nous concerne comme la correction de la priorité de la règle udev.
