Versionen av operativsystemet Qubes 4.2.2 \u00e4r nu tillg\u00e4nglig, som implementerar id\u00e9n om att anv\u00e4nda en hypervisor f\u00f6r strikt isolering av applikationer och operativsystemskomponenter (varje klass av applikationer och systemtj\u00e4nster k\u00f6rs i separata virtuella maskiner). F\u00f6r att k\u00f6ra rekommenderas ett system med 16 GB RAM (minst 6 GB) och en 64-bitars Intel- eller AMD-processor som st\u00f6djer VT-x med EPT\/AMD-v med RVI och VT-d\/AMD IOMMU, helst med en Intel GPU (NVIDIA- och AMD-gpu:er har inte testats tillr\u00e4ckligt v\u00e4l). Storleken p\u00e5 installationsavbilden \u00e4r 6 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<\/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 utg\u00e5van noteras en uppdatering av versionerna av program som bildar den grundl\u00e4ggande systemmilj\u00f6n (dom0). En mall har f\u00f6rberetts f\u00f6r att skapa virtuella milj\u00f6er baserade p\u00e5 Fedora 40. <\/p>\n

I version 4.2 har det inf\u00f6rts begr\u00e4nsningar f\u00f6r att skydda mot attacker relaterade till manipulation av unicode-tecken och ogiltiga teckenkoder i filnamn, som p\u00e5verkar anv\u00e4ndningen av utvidgade tecken i filnamn. Denna \u00e4ndring har lett till problem med kopiering och flyttning av filer som inneh\u00e5ller icke-latinska bokst\u00e4ver i namnet. I version 4.2.2 har det gamla beteendet vid hantering av filnamn \u00e5terst\u00e4llts som standard, och f\u00f6r att st\u00e4lla in detta har parametern \"allow-all-names\" lagts till i tj\u00e4nsten qubes.Filecopy.
