Un an apr\u00e8s la derni\u00e8re version publi\u00e9<\/a><\/noindex> mise \u00e0 jour du syst\u00e8me d'exploitation Qubes 4.0.2<\/a><\/noindex>, mettant en \u0153uvre<\/a><\/noindex> l'id\u00e9e d'utiliser un hyperviseur pour une isolation stricte des applications et des composants du syst\u00e8me d'exploitation (chaque classe d'applications et services syst\u00e8me fonctionne dans des machines virtuelles distinctes). Pour le d\u00e9marrage pr\u00e9par\u00e9<\/a><\/noindex> une image d'installation de 4,6 Go. Pour fonctionner il faut<\/a><\/noindex> un syst\u00e8me avec 4 Go de RAM et un processeur 64 bits Intel ou AMD prenant en charge les technologies VT-x avec EPT\/AMD-v avec RVI et VT-d\/AMD IOMMU, de pr\u00e9f\u00e9rence avec un GPU Intel (les GPU NVIDIA et AMD n'ont pas \u00e9t\u00e9 suffisamment test\u00e9s).<\/p>\n

Les applications dans Qubes sont r\u00e9parties en classes en fonction de l'importance des donn\u00e9es trait\u00e9es et des t\u00e2ches \u00e0 accomplir, chaque classe d'applications ainsi que les services syst\u00e8me (sous-syst\u00e8me r\u00e9seau, gestion du stockage, etc.). Lorsque l'utilisateur d\u00e9marre une application depuis le menu, cette application se lance dans une machine virtuelle sp\u00e9cifique, dans laquelle un serveur X distinct, un gestionnaire de fen\u00eatres simplifi\u00e9 et un pilote vid\u00e9o stub transmettent la sortie dans l'environnement de gestion en mode composite. Les applications sont ainsi accessibles sans interruption sur un m\u00eame bureau et se distinguent visuellement par des bordures de fen\u00eatre de couleur diff\u00e9rente. Chaque environnement a un acc\u00e8s en lecture au syst\u00e8me de fichiers racine de base et au stockage local, sans chevauchement avec les stockages d'autres environnements. L'interface utilisateur est construite sur Xfce.<\/p>\n

La nouvelle version met \u00e0 jour les versions des programmes formant l'environnement syst\u00e8me de base (dom0), notamment le passage au noyau Linux 4.19 (le noyau 4.14 \u00e9tait pr\u00e9c\u00e9demment utilis\u00e9). Les mod\u00e8les
\npour cr\u00e9er des environnements virtuels ont \u00e9t\u00e9 mis \u00e0 jour vers Fedora 30, Debian 10 et Whonix 15<\/a><\/noindex>.<\/p>\n
