Objavljena je nova verzija operativnog sustava Qubes 4.2.1, koja implementira ideju kori\u0161tenja hipervizora za strogu izolaciju aplikacija i komponenti OS-a (svaka klasa aplikacija i sustavni servisi rade u odvojenim virtualnim ma\u0161inama). Preporu\u010duje se sustav s 16 GB RAM-a (minimum — 6 GB) i 64-bitnim Intel ili AMD CPU s podr\u0161kom za VT-x s EPT\/AMD-v s RVI i VT-d\/AMD IOMMU, a po\u017eeljno je imati i Intel GPU (NVIDIA i AMD GPU nisu dovoljno dobro testirani). Veli\u010dina instalacijskog imid\u017ea — 6 GB (x86_64). <\/p>\n

Aplikacije u Qubesu su podijeljene u klase ovisno o va\u017enosti obra\u0111enih podataka i zadatcima koji se rje\u0161avaju. Svaka klasa aplikacija (npr. posao, zabava, bankovne transakcije), kao i sustavske usluge (mre\u017eni podsustav, vatrozid, rad s pohranjivanjem, USB stog itd.), rade u odvojenim virtualnim ma\u0161inama<\/a>, pokretanim kori\u0161tenjem hiper-vizora Xen. Pri tome navedene aplikacije su dostupne unutar jednog radnog stola i isti\u010du se razli\u010ditim bojama okvira prozora. Svako okru\u017eenje ima pristup samo za \u010ditanje osnovnom korijenskom datote\u010dnom sustavu i lokalnoj pohrani, koja se ne preklapa s pohranama drugih okru\u017eenja, za organizaciju interakcije aplikacija koristi se posebna usluga. <\/p>\n<\/p>\n

Kao osnova za stvaranje virtualnih okru\u017eenja mo\u017ee se koristiti bazni paket Fedora i Debian, tako\u0111er zajednica podr\u017eava predlo\u0161ke za Ubuntu, Gentoo i Arch Linux. Mogu\u0107e je organizirati pristup aplikacijama u virtualnoj ma\u0161ini s Windowsom, kao i kreirati virtualnih ma\u0161ina<\/a> na bazi Whonix za omogu\u0107avanje anonimnog pristupa putem Tora. Korisni\u010dko su\u010delje izgra\u0111eno je na Xfce-u. Kada korisnik pokrene aplikaciju iz izbornika, ta aplikacija se pokre\u0107e u odre\u0111enoj virtualnoj ma\u0161ini. Sadr\u017eaj virtualnih okru\u017eenja odre\u0111uje se skupom predlo\u017eaka. <\/p>\n

U novom izdanju navedeno je a\u017euriranje verzija programa koji \u010dine temeljno sistemsko okru\u017eenje (dom0). Pripremljen je \u0161ablon za stvaranje virtualnih okru\u017eenja na bazi Fedora 39. Po defaultu je aktivirana jezgra Linux 6.6, \u0161to je smanjilo broj situacija u kojima je potrebna instalacija paketa s jezgrom kernel-latest na sustavima s novim hardverom.
