Dopo un anno dall'ultimo rilascio pubblicato<\/a><\/noindex> aggiornamento del sistema operativo Qubes 4.0.2<\/a><\/noindex>, realizzando<\/a><\/noindex> l'idea di utilizzare un hypervisor per l'isolamento rigoroso delle applicazioni e dei componenti del sistema operativo (ogni classe di applicazioni e i servizi di sistema funzionano in macchine virtuali separate). Per il caricamento \u00e8 stato preparato<\/a><\/noindex> un'immagine di installazione di 4,6 GB. Per funzionare \u00e8 necessario<\/a><\/noindex> sistema con 4 GB di RAM e CPU a 64 bit Intel o AMD con supporto per tecnologie VT-x con EPT\/AMD-v con RVI e VT-d\/AMD IOMMU, \u00e8 preferibile la presenza di una GPU Intel (le GPU NVIDIA e AMD non sono state testate a sufficienza).<\/p>\n

Le applicazioni in Qubes sono suddivise in classi a seconda dell'importanza dei dati trattati e degli obiettivi da raggiungere, ciascuna classe di applicazioni, cos\u00ec come i servizi di sistema (sistema di rete, gestione dello storage, ecc.). Quando l'utente avvia un'applicazione dal menu, questa si avvia in una specifica macchina virtuale, nella quale viene eseguito un server X separato, un gestore di finestre semplificato e un driver video-fake, che trasmette l'output all'ambiente di controllo in modalit\u00e0 composita. In questo modo, le applicazioni sono accessibili senza soluzione di continuit\u00e0 all'interno di un unico desktop e vengono distinte visivamente da un colore di cornice diverso. Ogni ambiente ha accesso in sola lettura al filesystem radice di base e allo storage locale, che non si sovrappone agli storage di altri ambienti. L'interfaccia utente \u00e8 basata su Xfce.<\/p>\n

Nel nuovo rilascio sono state aggiornate le versioni dei programmi che formano l'ambiente di sistema di base (dom0), incluso il passaggio al kernel Linux 4.19 (precedentemente era utilizzato il kernel 4.14). I template
\nper la creazione di ambienti virtuali sono stati aggiornati a Fedora 30, Debian 10 e Whonix 15<\/a><\/noindex>.<\/p>\n
