Udgivelsen af operativsystemet Qubes 4.2.2 er tilg\u00e6ngelig, som implementerer ideen om at bruge en hypervisor til striks isolation af applikationer og OS-komponenter (hver applikationsklasse og systemtjenester k\u00f8rer i separate virtuelle maskiner). For at k\u00f8re systemet anbefales det at have 16 GB RAM (minimum - 6 GB) og en 64-bit Intel eller AMD CPU, der underst\u00f8tter VT-x med EPT \/ AMD-v med RVI og VT-d \/ AMD IOMMU. Det anbefales at have Intel GPU (NVIDIA og AMD GPU'er er ikke tilstr\u00e6kkeligt testet). St\u00f8rrelsen p\u00e5 installationsbilledet er 6 GB (x86_64). <\/p>\n

Applikationerne i Qubes er opdelt i klasser afh\u00e6ngigt af vigtigheden af de behandlede data og de l\u00f8ste opgaver. Hver applikationsklasse (f.eks. arbejde, underholdning, banktransaktioner), samt systemtjenester (netv\u00e6rksunderst\u00f8ttelse, firewall, datalagring, USB-stak osv.), k\u00f8rer i separate virtuelle maskiner<\/a>, der k\u00f8rer ved hj\u00e6lp af Xen-hypervisoren. De n\u00e6vnte applikationer er tilg\u00e6ngelige inden for en enkelt arbejdsflade og adskilles visuelt med forskellige farver p\u00e5 vinduesrammen. Hvert milj\u00f8 har L\u00e6s-adgang til den grundl\u00e6ggende rodfilsystem og lokal lagring, der ikke overlapper med lagringen fra andre milj\u00f8er, og der bruges en speciel tjeneste til at organisere interaktionen mellem applikationer. <\/p>\n<\/p>\n

Som grundlag for oprettelse af virtuelle milj\u00f8er kan der anvendes paketbaserede Fedora og Debian, og samfundet vedligeholder ogs\u00e5 skabeloner til Ubuntu, Gentoo og Arch Linux. Der er mulighed for at f\u00e5 adgang til applikationer i en virtuel maskine med Windows, samt at oprette virtual machines<\/a> en Whonix-baseret l\u00f8sning for at sikre anonym adgang via Tor. Brugergr\u00e6nsefladen er bygget p\u00e5 Xfce. N\u00e5r brugeren starter en applikation fra menuen, starter applikationen i en specifik virtuel maskine. Indholdet af de virtuelle milj\u00f8er defineres af et s\u00e6t skabeloner. <\/p>\n

I den nye version er der blevet bem\u00e6rket opdateringer af programmerne, der danner det grundl\u00e6ggende systemmilj\u00f8 (dom0). Der er udarbejdet en skabelon til oprettelse af virtuelle milj\u00f8er baseret p\u00e5 Fedora 40. <\/p>\n

I version 4.2 er der blevet indf\u00f8rt begr\u00e6nsninger for brugen af udvidede tegn i filnavne for at beskytte mod angreb relateret til manipulation med unicode-tegn og forkert tegnkode. Denne \u00e6ndring har f\u00f8rt til problemer med kopiering og flytning af filer, der indeholder ikke-latinske bogstaver i navnet. I version 4.2.2 er det gamle adf\u00e6rd ved behandling af filnavne som standard genoprettet, og for at konfigurere dette er parameteren \u00aballow-all-names\u00bb blevet tilf\u00f8jet til qubes.Filecopy tjenesten.
