Systemet Qubes 4.3.2 \u00e4r nu tillg\u00e4ngligt, vilket implementerar id\u00e9n om att anv\u00e4nda en hypervisor f\u00f6r strikt isolering av applikationer och operativsystemkomponenter (varje klass av applikationer och systemtj\u00e4nster k\u00f6rs i separata virtuella maskiner). F\u00f6r att k\u00f6ra systemet rekommenderas 16 GB RAM (minimum 6 GB) och en 64-bitars CPU fr\u00e5n Intel eller AMD som st\u00f6der VT-x med EPT\/AMD-v med RVI och VT-d eller AMD IOMMU, med en f\u00f6rdel f\u00f6r en Intel GPU (NVIDIA och AMD GPU:er \u00e4r inte tillr\u00e4ckligt testade). Storleken p\u00e5 installationsbilden \u00e4r 8 GB (x86_64). <\/p>\n

Applikationer i Qubes \u00e4r uppdelade i klasser beroende p\u00e5 hubert av behandlade data och l\u00f6sta uppgifter. Varje klass av applikationer (t.ex. arbete, underh\u00e5llning, bank\u00e4renden) samt systemtj\u00e4nster (n\u00e4tverksunderlag, brandv\u00e4gg, lagring, USB-stack etc.) k\u00f6rs i separata virtuella maskiner<\/a>, som startas med hj\u00e4lp av hypervisorn Xen. Dessa applikationer \u00e4r tillg\u00e4ngliga inom en arbetsytan och framh\u00e4vs f\u00f6r tydlighet med olika f\u00e4rger runt f\u00f6nstret. Varje milj\u00f6 har l\u00e4s\u00e5tkomst till grunden rota FS och lokal lagring, som inte korsar med lagringen i andra milj\u00f6er, f\u00f6r interaktion mellan applikationer anv\u00e4nds en s\u00e4rskild tj\u00e4nst. <\/p>\n

Som grund f\u00f6r att skapa virtuella milj\u00f6er kan en paketbas fr\u00e5n Fedora och Debian anv\u00e4ndas, och \u00e4ven gemenskapen st\u00f6der mallar f\u00f6r Ubuntu, Gentoo och Arch Linux. Det \u00e4r m\u00f6jligt att organisera \u00e5tkomst till applikationer i en virtuell maskin med Windows, samt att skapa virtuella maskiner<\/a> baserat p\u00e5 Whonix f\u00f6r att s\u00e4kerst\u00e4lla anonym \u00e5tkomst via Tor. Anv\u00e4ndargr\u00e4nssnittet \u00e4r byggt p\u00e5 Xfce. N\u00e4r anv\u00e4ndaren startar en applikation fr\u00e5n menyn, startar denna applikation i en viss virtuell maskin. Inneh\u00e5llet i de virtuella milj\u00f6erna definieras av en upps\u00e4ttning mallar. <\/p>\n

I den nya versionen har mallen f\u00f6r virtuella milj\u00f6er uppdaterats till Fedora 44. Paketet med Linux-k\u00e4rnan har uppdaterats till version 7.2. Sammanlagda fel och s\u00e5rbarheter har \u00e5tg\u00e4rdats, inklusive allvarliga s\u00e5rbarheter i hypervisorn Xen och en kritisk s\u00e5rbarhet i verktyget \"qvm-copy-to-vm\", som m\u00f6jligg\u00f6r att kringg\u00e5 isoleringen och k\u00f6ra kod p\u00e5 domeneringsniv\u00e5 Dom0.
