Na voljo je izdal operacijski sistem Qubes 4.3.2, ki uresni\u010duje idejo uporabe hipervizorja za strogo izolacijo aplikacij in komponent operacijskega sistema (vsaka kategorija aplikacij in sistemski storitveni programi delujejo v lo\u010denih virtualnih mehinskih enotah). Priporo\u010damo sistem s 16 GB RAM-a (najmanj 6 GB) in 64-bitnim procesorjem Intel ali AMD, ki podpira tehnologije VT-x s EPT\/AMD-v s RVI in VT-d ali AMD IOMMU, za\u017eeleno je imeti tudi GPU Intel (GPU NVIDIA in AMD niso dovolj dobro preizku\u0161eni). Velikost namestitvenega slike je 8 GB (x86_64). <\/p>\n

Aplikacije v Qubes so razdeljene v kategorije glede na pomembnost obdelanih podatkov in re\u0161evane naloge. Vsaka kategorija aplikacij (na primer delo, zabava, ban\u010dne storitve), kot tudi sistemske storitve (omre\u017ena podpora, po\u017earni zid, delo s shrambo, USB-\u0161tevec itd.), delujejo v lo\u010denih virtualnim ma\u0161inama<\/a>, ki se zagnajo z uporabo hipervizorja Xen. Pri tem so navedene aplikacije dostopne znotraj iste delovne povr\u0161ine in so za preglednost ozna\u010dene z razli\u010dno barvo obrobe okna. Vsako okolje ima dostop za branje do osnovnega korenskega datote\u010dnega sistema in lokalne shrambe, ki se ne prekrivajo s shrambo drugih okolij. Za organizacijo interakcije aplikacij se uporablja posebna storitev. <\/p>\n

Kot osnova za oblikovanje virtualnih okolij se lahko uporablja paketna baza Fedora in Debian, prav tako skupnost podpira predloge za Ubuntu, Gentoo in Arch Linux. Mo\u017ena je organizacija dostopa do aplikacij v virtualnem ra\u010dunalniku z Windows, prav tako je mo\u017eno ustvariti virtualnih naprav<\/a> na osnovi Whonix za zagotavljanje anonimnega dostopa preko Tora. Uporabni\u0161ki vmesnik je zgrajen na osnovi Xfce. Ko uporabnik iz menija za\u017eene aplikacijo, se ta aplikacija za\u017eene v dolo\u010denem virtualnem ra\u010dunalniku. Vsebina virtualnih okolij je dolo\u010dena z naborom predlog. <\/p>\n

V novi razli\u010dici je bil predloga za virtualna okolja posodobljen na Fedora 44. Paket s jedrom Linuxa je bil posodobljen na razli\u010dico 7.2. Odpravljene so bile kopi\u010dene napake in ranljivosti, vklju\u010dno z nevarnimi ranljivostmi v hipervizorju Xen in kriti\u010dno ranljivostjo v orodju \u201eqvm-copy-to-vm\u201c, ki omogo\u010da obvladovanje izolacije in izvajanje kode na ravni Dom0.
