\u00c8 stato rilasciato un aggiornamento del sistema operativo Qubes 4.1.1, che implementa l'idea di utilizzare un hypervisor per una rigorosa isolazione delle applicazioni e dei componenti di sistema (ogni classe di applicazioni e i servizi di sistema funzionano in macchine virtuali separate). \u00c8 necessaria una macchina con 6 GB di RAM e un CPU a 64 bit Intel o AMD con supporto per le tecnologie VT-x con EPT\/AMD-v con RVI e VT-d\/AMD IOMMU; \u00e8 preferibile avere una GPU Intel (le GPU NVIDIA e AMD non sono state testate a sufficienza). La dimensione dell'immagine di installazione \u00e8 di 5,5 GB. <\/p>\n

Le applicazioni in Qubes sono suddivise in classi in base all'importanza dei dati trattati e delle attivit\u00e0 svolte. Ogni classe di applicazioni (ad esempio, lavoro, intrattenimento, operazioni bancarie), cos\u00ec come i servizi di sistema (sottosistema di rete, firewall, gestione dello storage, stack USB, ecc.) funzionano in macchine virtuali<\/a>, avviate utilizzando l'hypervisor Xen. Queste applicazioni sono accessibili all'interno di un'unica scrivania e sono evidenziate per chiarezza con un bordo colorato attorno alla finestra. Ogni ambiente ha accesso in lettura al file system root di base e allo storage locale, che non si sovrappone agli storage di altri ambienti; per organizzare l'interazione tra le applicazioni viene utilizzato un servizio speciale. <\/p>\n

Come base per la formazione degli ambienti virtuali possono essere utilizzati i repository di Fedora e Debian; la comunit\u00e0 supporta anche template per Ubuntu, Gentoo e Arch Linux. \u00c8 possibile organizzare l'accesso alle applicazioni in una macchina virtuale con Windows, cos\u00ec come creare macchine virtuali<\/a> basate su Whonix per garantire un accesso anonimo tramite Tor. L'interfaccia utente \u00e8 costruita sulla base di Xfce. Quando un utente avvia un'applicazione dal menu, questa viene avviata in una specifica macchina virtuale. Il contenuto degli ambienti virtuali \u00e8 determinato da un insieme di template. <\/p>\n

Nella nuova versione \u00e8 stato segnalato solo un aggiornamento delle versioni dei programmi che formano l'ambiente di base del sistema (dom0). \u00c8 stato preparato un modello per la creazione di ambienti virtuali basati su Fedora 36. Di default \u00e8 proposto il kernel Linux 5.15. \u00c8 prevista la fine del supporto per il ramo Qubes 4.0 il 4 agosto; si consiglia agli utenti del ramo precedente di passare a Qubes 4.1.
