\u00c8 stato rilasciato un aggiornamento del sistema operativo Qubes 4.0.4, che realizza l'idea di utilizzare un hypervisor per una severa isolamento delle applicazioni e dei componenti del sistema operativo (ogni classe di applicazioni e servizi di sistema funziona in macchine virtuali separate). \u00c8 stata preparata un'immagine di installazione di 4,9 GB per il download. Per funzionare \u00e8 necessaria una macchina con 4 GB di RAM e una CPU Intel o AMD a 64 bit che supporti le tecnologie VT-x con EPT\/AMD-v con RVI e VT-d\/AMD IOMMU, preferibilmente con GPU Intel (le GPU NVIDIA e AMD non sono state testate a sufficienza). <\/p>\n

Le applicazioni in Qubes sono suddivise in classi in base all'importanza dei dati trattati e delle attivit\u00e0 svolte, con ogni classe di applicazioni e i servizi di sistema (sottosistema di rete, gestione dello storage, ecc.). Quando l'utente avvia un'applicazione dal menu, questa si avvia in un determinato macchina virtuale<\/a>, in cui viene eseguito un server X separato, un gestore di finestre semplificato e un driver video fittizio, che trasmette l'output all'ambiente di gestione in modalit\u00e0 composita. Le applicazioni sono accessibili senza soluzione di continuit\u00e0 all'interno di un'unica scrivania e sono evidenziate per la visibilit\u00e0 da diversi colori del contorno della finestra. Ogni ambiente ha accesso in sola lettura al filesystem root di base e allo storage locale, che non interseca gli storage di altri ambienti. L'interfaccia utente \u00e8 basata su Xfce. <\/p>\n

Nella nuova versione \u00e8 stata segnalata solo l'aggiornamento delle versioni dei programmi che formano l'ambiente sistemico di base (dom0). Sono stati preparati modelli per la creazione di ambienti virtuali basati su Fedora 32, Debian 10 e Whonix 15. Il kernel Linux 5.4 \u00e8 stato proposto come predefinito.
