Versiunea sistemului de operare Qubes 4.3.2 este disponibil\u0103, implement\u00e2nd idee utiliz\u0103rii unui hypervisor pentru izolarea strict\u0103 a aplica\u021biilor \u0219i componentelor OS (fiecare categorie de aplica\u021bii \u0219i servicii de sistem func\u021bioneaz\u0103 \u00een ma\u0219ini virtuale separate). Se recomand\u0103 un sistem cu 16 GB RAM (minimum \u2014 6 GB) \u0219i CPU Intel sau AMD pe 64 de bi\u021bi cu suport pentru tehnologiile VT-x cu EPT\/AMD-v cu RVI \u0219i VT-d sau AMD IOMMU, preferabil cu GPU Intel (GPU-urile NVIDIA \u0219i AMD nu sunt suficient de bine testate). Dimensiunea imaginii de instalare este de 8 GB (x86_64). <\/p>\n

Aplica\u021biile din Qubes sunt \u00eemp\u0103r\u021bite \u00een clase \u00een func\u021bie de importan\u021ba datelor procesate \u0219i a sarcinilor desf\u0103\u0219urate. Fiecare clas\u0103 de aplica\u021bii (de exemplu, munc\u0103, divertisment, opera\u021biuni bancare), precum \u0219i serviciile de sistem (subsystema de re\u021bea, firewall, gestionarea stoc\u0103rii, stack USB etc.), func\u021bioneaz\u0103 \u00een ma\u0219ini virtuale separate, lansate utiliz\u00e2nd hipervizorul Xen. Aceste aplica\u021bii sunt disponibile \u00een cadrul acelea\u0219i sesiuni de lucru \u0219i sunt eviden\u021biate printr-o ram\u0103 de culoare diferit\u0103. Fiecare mediu are acces read-only la sistemul de fi\u0219iere r\u0103d\u0103cin\u0103 de baz\u0103 \u0219i la stocarea local\u0103, care nu se suprapune cu stoc\u0103rile altor medii; pentru a organiza interac\u021biunea aplica\u021biilor se folose\u0219te un serviciu special. <\/p>\n

Ca baz\u0103 pentru formarea mediilor virtuale poate fi utilizat\u0103 baza de pachete Fedora \u0219i Debian, de asemenea, comunitatea suport\u0103 \u0219abloane pentru Ubuntu, Gentoo \u0219i Arch Linux. Este posibil\u0103 organizarea accesului la aplica\u021biile dintr-o ma\u0219in\u0103 virtual\u0103 cu Windows, precum \u0219i crearea ma\u0219ini virtuale<\/a> pe baza Whonix pentru a asigura un acces anonim prin Tor. Interfa\u021ba utilizatorului este construit\u0103 pe baza Xfce. C\u00e2nd utilizatorul porne\u0219te o aplica\u021bie din meniu, aceast\u0103 aplica\u021bie se porne\u0219te \u00eentr-o anumit\u0103 ma\u0219in\u0103 virtual\u0103. Con\u021binutul mediilor virtuale este determinat de un set de \u0219abloane. <\/p>\n

\u00cen noua versiune, \u0219ablonul pentru mediile virtuale a fost actualizat la Fedora 44. Pachetul cu kernel Linux a fost actualizat la versiunea 7.2. Au fost remediate erorile \u0219i vulnerabilit\u0103\u021bile acumulate, inclusiv vulnerabilit\u0103\u021bile critice din hypervisorul Xen \u0219i vulnerabilitatea critic\u0103 din utilitarul \u201eqvm-copy-to-vm\u201d, care permite ocolirea izol\u0103rii \u0219i executarea codului la nivelul Dom0.
