Dostupna je verzija operacijskog sustava Qubes 4.3.2, koja realizira ideju kori\u0161tenja hipervizora za strogu izolaciju aplikacija i komponenti OS-a (svaka klasa aplikacija i sustavne usluge rade u odvojenim virtualnim strojevima). Za rad se preporu\u010duje sustav s 16 GB RAM-a (minimalno - 6 GB) i 64-bitni CPU Intel ili AMD s podr\u0161kom za tehnologije VT-x s EPT\/AMD-v s RVI i VT-d ili AMD IOMMU, po\u017eeljno je imati GPU Intel (GPU NVIDIA i AMD nisu dovoljno dobro testirani). Veli\u010dina instalacijskog imid\u017ea - 8 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

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 novoj verziji, predlo\u017eak za virtualna okru\u017eenja a\u017euriran je na Fedora 44. Paket s Linux jezgricom a\u017euriran je na verziju 7.2. Uklonjene su akumulirane gre\u0161ke i sigurnosne ranjivosti, uklju\u010duju\u0107i opasne ranjivosti u hipervizoru Xen i kriti\u010dnu ranjivost u utilitaru 'qvm-copy-to-vm', koja omogu\u0107ava zaobila\u017eenje izolacije i izvr\u0161avanje koda na razini Dom0.
