Foi lan\u00e7ado uma atualiza\u00e7\u00e3o do sistema operacional Qubes 4.0.4, que implementa a ideia de usar um hipervisor para o isolamento rigoroso de aplicativos e componentes do sistema operacional (cada classe de aplicativos e servi\u00e7os do sistema opera em m\u00e1quinas virtuais separadas). A imagem de instala\u00e7\u00e3o de 4,9 GB est\u00e1 dispon\u00edvel para download. \u00c9 necess\u00e1rio ter um sistema com 4 GB de RAM e um CPU Intel ou AMD de 64 bits que suporte as tecnologias VT-x com EPT\/AMD-v com RVI e VT-d\/AMD IOMMU, sendo desej\u00e1vel a presen\u00e7a de uma GPU Intel (as GPUs NVIDIA e AMD n\u00e3o foram testadas t\u00e3o extensivamente). <\/p>\n

Os aplicativos no Qubes s\u00e3o divididos em classes, dependendo da import\u00e2ncia dos dados processados e das tarefas realizadas, cada classe de aplicativos, bem como os servi\u00e7os do sistema (subsystema de rede, opera\u00e7\u00e3o com armazenamento, etc.). Quando o usu\u00e1rio inicia um aplicativo a partir do menu, esse aplicativo \u00e9 executado em um ambiente espec\u00edfico m\u00e1quina virtual<\/a>, onde um servidor X separado, um gerenciador de janelas simplificado e um driver gr\u00e1fico fict\u00edcio operam, transmitindo a sa\u00edda para o ambiente de controle em modo de composi\u00e7\u00e3o. Nesse processo, os aplicativos est\u00e3o acess\u00edveis de forma cont\u00ednua em uma \u00fanica \u00e1rea de trabalho e se destacam visualmente com diferentes cores de borda nas janelas. Cada ambiente tem acesso de leitura ao sistema de arquivos raiz b\u00e1sico e ao armazenamento local, que n\u00e3o se sobrep\u00f5e aos armazenamentos de outros ambientes. A interface do usu\u00e1rio \u00e9 baseada no Xfce. <\/p>\n

A nova vers\u00e3o traz apenas atualiza\u00e7\u00f5es das vers\u00f5es dos programas que formam o ambiente b\u00e1sico do sistema (dom0). Foram preparados modelos para a cria\u00e7\u00e3o de ambientes virtuais baseados no Fedora 32, Debian 10 e Whonix 15. Por padr\u00e3o, \u00e9 oferecido o kernel Linux 5.4.
