Opdateringen af operativsystemet Qubes 4.1.1 er blevet udgivet, som realiserer ideen om at bruge en hypervisor til streng isolering af applikationer og systemkomponenter (hver applikationsklasse og systemtjenester k\u00f8rer i separate virtuelle maskiner). For at kunne k\u00f8re kr\u00e6ves et system med 6 GB RAM og en 64-bit CPU fra Intel eller AMD, der underst\u00f8tter VT-x med EPT\/AMD-v med RVI og VT-d\/AMD IOMMU; det anbefales at have et Intel GPU (NVIDIA og AMD GPU'er er ikke tilstr\u00e6kkeligt testet). St\u00f8rrelsen p\u00e5 installationsbilledet er 5,5 GB. <\/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 der kun bem\u00e6rket en opdatering af versionerne af de programmer, der udg\u00f8r det grundl\u00e6ggende systemmilj\u00f8 (dom0). En skabelon er udarbejdet til oprettelse af virtuelle milj\u00f8er baseret p\u00e5 Fedora 36. Som standard er Linux-kernen 5.15 tilbudt. Den 4. august er det planlagt at stoppe underst\u00f8ttelsen af Qubes 4.0-grenen, og brugerne af den gamle gren anbefales at opgradere til brugen af Qubes 4.1.
