Udgivelsen af operativsystemet Qubes 4.2.1 er pr\u00e6senteret, som realiserer id\u00e9en om at bruge en hypervisor til streng isolation af applikationer og operativsystemkomponenter (hver applikationsklasse og systemtjenester k\u00f8rer i separate virtuelle maskiner). Det anbefales at bruge et system med 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 er \u00f8nskeligt at have en 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 opdateringer af de programmer, der danner det grundl\u00e6ggende systemmilj\u00f8 (dom0). En skabelon til oprettelse af virtuelle milj\u00f8er baseret p\u00e5 Fedora 39 er blevet forberedt. Som standard er Linux-kernen 6.6 aktiveret, hvilket har reduceret antallet af situationer, hvor det er n\u00f8dvendigt at installere pakken kernel-latest p\u00e5 systemer med nyt udstyr.
