Udgivelsen af operativsystemet Qubes 4.3.2 er tilg\u00e6ngelig, hvilket realiserer id\u00e9en om at bruge en hypervisor til striks isolering af applikationer og OS-komponenter (hver applikationsklasse og systemtjenester k\u00f8rer i separate virtuelle maskiner). Det anbefales at have et system med 16 GB RAM (minimum - 6 GB) og en 64-bit Intel eller AMD CPU med underst\u00f8ttelse af VT-x med EPT\/AMD-v med RVI og VT-d eller AMD IOMMU, helst med Intel GPU (NVIDIA og AMD GPU'er er ikke tilstr\u00e6kkeligt testet). St\u00f8rrelsen p\u00e5 installationsbilledet er 8 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

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 skabelonen til virtuelle milj\u00f8er opdateret til Fedora 44. Linux-kernen er opdateret til version 7.2. Akkumulerede fejl og s\u00e5rbarheder er rettet, herunder alvorlige s\u00e5rbarheder i hypervisoren Xen og en kritisk s\u00e5rbarhed i v\u00e6rkt\u00f8jet \u00abqvm-copy-to-vm\u00bb, som g\u00f8r det muligt at omg\u00e5 isolationen og k\u00f8re kode p\u00e5 Dom0-niveau.
