The release of the Qubes operating system version 4.3.2 is now available, implementing the idea of using a hypervisor for strict isolation of applications and OS components (each class of applications and system services operates in separate virtual machines). It is recommended to use a system with 16 GB of RAM (minimum - 6 GB) and a 64-bit Intel or AMD CPU that supports VT-x with EPT\/AMD-v with RVI and VT-d or AMD IOMMU, ideally having an Intel GPU (NVIDIA and AMD GPUs have not been sufficiently tested). The size of the installation image is 8 GB (x86_64). <\/p>\n
Applications in Qubes are divided into classes based on the importance of the processed data and the tasks to be accomplished. Each application class (for example, work, entertainment, banking operations), along with system services (network subsystem, firewall, storage management, USB stack, etc.), operates in separate virtual machines, launched using the Xen hypervisor. These applications are accessible within a single desktop and are visually distinguished by different colored window borders. Each environment has read access to the underlying root filesystem and local storage, which does not overlap with the storage of other environments, with a special service facilitating interaction between applications. <\/p>\n
