Foi lan\u00e7ado o sistema operacional Qubes 4.2.1, que implementa a ideia de usar um hipervisor para um isolamento rigoroso de aplicativos e componentes do sistema operacional (cada classe de aplicativos e servi\u00e7os do sistema opera em m\u00e1quinas virtuais separadas). Recomenda-se um sistema com 16 GB de RAM (m\u00ednimo \u2014 6 GB) e um CPU Intel ou AMD de 64 bits com suporte para as tecnologias VT-x com EPT \/ AMD-v com RVI e VT-d \/ IOMMU AMD. \u00c9 prefer\u00edvel ter uma GPU Intel (as GPUs NVIDIA e AMD n\u00e3o foram testadas o suficiente). O tamanho da imagem de instala\u00e7\u00e3o \u00e9 de 6 GB (x86_64). <\/p>\n

Os aplicativos no Qubes s\u00e3o divididos em classes com base na import\u00e2ncia dos dados tratados e nas tarefas realizadas. Cada classe de aplicativos (por exemplo, trabalho, entretenimento, opera\u00e7\u00f5es banc\u00e1rias), assim como servi\u00e7os do sistema (subsistema de rede, firewall, gerenciamento de armazenamento, pilha USB, etc.), opera em separado m\u00e1quinas virtuais<\/a>, sendo executados usando o hipervisor Xen. Neste caso, os aplicativos indicados est\u00e3o dispon\u00edveis dentro de uma \u00fanica \u00e1rea de trabalho e s\u00e3o destacados por diferentes cores na borda da janela. Cada ambiente tem acesso de leitura ao sistema de arquivos raiz b\u00e1sico e ao armazenamento local, que n\u00e3o se sobrep\u00f5e ao armazenamento de outros ambientes, utilizando um servi\u00e7o especial para organizar a intera\u00e7\u00e3o entre aplicativos. <\/p>\n<\/p>\n

Como base para a forma\u00e7\u00e3o de ambientes virtuais, pode-se utilizar reposit\u00f3rios de pacotes do Fedora e Debian, al\u00e9m de que a comunidade d\u00e1 suporte a templates para Ubuntu, Gentoo e Arch Linux. \u00c9 poss\u00edvel organizar o acesso a aplicativos em uma m\u00e1quina virtual com Windows, assim como criar m\u00e1quinas virtuais<\/a> com base no Whonix para garantir acesso an\u00f4nimo atrav\u00e9s do Tor. A interface do usu\u00e1rio \u00e9 constru\u00edda sobre o Xfce. Quando o usu\u00e1rio inicia um aplicativo atrav\u00e9s do menu, esse aplicativo \u00e9 iniciado em uma m\u00e1quina virtual espec\u00edfica. O conte\u00fado dos ambientes virtuais \u00e9 definido por um conjunto de templates. <\/p>\n

A nova vers\u00e3o traz uma atualiza\u00e7\u00e3o das vers\u00f5es dos programas que formam o ambiente b\u00e1sico do sistema (dom0). Um template foi preparado para a cria\u00e7\u00e3o de ambientes virtuais com base no Fedora 39. O kernel Linux 6.6 \u00e9 utilizado por padr\u00e3o, o que reduziu o n\u00famero de situa\u00e7\u00f5es em que \u00e9 necess\u00e1rio instalar o pacote com o kernel kernel-latest em sistemas com hardware novo.
