Um ano ap\u00f3s o \u00faltimo lan\u00e7amento publicou-se<\/a><\/noindex> atualiza\u00e7\u00e3o do sistema operacional Qubes 4.0.2<\/a><\/noindex>, implementando<\/a><\/noindex> a ideia de usar um hipervisor para o isolamento rigoroso de aplica\u00e7\u00f5es e componentes do sistema operacional (cada classe de aplica\u00e7\u00e3o e servi\u00e7os do sistema opera em m\u00e1quinas virtuais separadas). Para a instala\u00e7\u00e3o est\u00e1 preparado<\/a><\/noindex> \u00e9 necess\u00e1rio um arquivo de imagem de 4,6 GB. Para funcionar \u00e9 preciso<\/a><\/noindex> um sistema com 4 GB de RAM e CPU Intel ou AMD de 64 bits com suporte para tecnologias VT-x com EPT\/AMD-v com RVI e VT-d\/AMD IOMMU, idealmente com GPU Intel (GPUs NVIDIA e AMD n\u00e3o foram testadas suficientemente bem).<\/p>\n

As aplica\u00e7\u00f5es no Qubes s\u00e3o divididas em classes com base na import\u00e2ncia dos dados processados e das tarefas a serem resolvidas, cada classe de aplica\u00e7\u00e3o, bem como os servi\u00e7os do sistema (subsystems de rede, manipula\u00e7\u00e3o de armazenamento, etc.). Quando o usu\u00e1rio inicia uma aplica\u00e7\u00e3o do menu, essa aplica\u00e7\u00e3o \u00e9 iniciada em uma m\u00e1quina virtual espec\u00edfica, na qual um servidor X separado \u00e9 executado, gerenciador de janelas simplificado e driver de v\u00eddeo stub, transmitindo a sa\u00edda para o ambiente de controle em modo compositionado. Assim, as aplica\u00e7\u00f5es est\u00e3o acess\u00edveis sem interrup\u00e7\u00f5es dentro de uma \u00fanica \u00e1rea de trabalho e s\u00e3o destacadas por cores diferentes nos contornos das 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

Na nova vers\u00e3o, as vers\u00f5es dos programas que comp\u00f5em o ambiente b\u00e1sico do sistema (dom0) foram atualizadas, incluindo a atualiza\u00e7\u00e3o para o kernel Linux 4.19 (anteriormente utilizava-se o kernel 4.14). Os templates
\npara a cria\u00e7\u00e3o de ambientes virtuais foram atualizados para Fedora 30, Debian 10 e Whonix 15<\/a><\/noindex>.<\/p>\n
