An update to the Qubes 4.0.4 operating system has been created, which implements the idea of using a hypervisor for strict isolation of applications and OS components (each class of applications and system services runs in separate virtual machines). A 4.9 GB installation image has been prepared for download. To work, you need a system with 4 GB of RAM and a 64-bit Intel or AMD CPU with support for VT-x with EPT/AMD-v with RVI and VT-d/AMD IOMMU technologies, preferably an Intel GPU (NVIDIA and AMD GPUs are not well tested ).
Applications in Qubes are divided into classes based on the importance of the data they process and the tasks they solve. Each application class also includes system services (network subsystem, storage, etc.). When a user launches an application from the menu, the application starts in a specific virtual machine, which runs a separate X server, a simplified window manager, and a stub video driver that renders output to the host environment in composite mode. Applications are seamlessly accessible within a single desktop and are highlighted with different window border colors for clarity. Each environment has read access to the underlying root filesystem and local storage, which does not interfere with the storage of other environments. The user interface is built on Xfce.
The new release only includes updates to the versions of programs that form the base system environment (dom0). Templates for creating virtual environments based on Fedora 32 have been prepared. Debian 10 and Whonix 15. The default kernel is Linux 5.4.
