A system with 16 GB of RAM (minimum - 6 GB) and a 64-bit Intel or AMD CPU supporting VT-x with EPT \/ AMD-v with RVI and VT-d \/ AMD IOMMU technologies is recommended, ideally with an Intel GPU (NVIDIA and AMD GPUs are not well-tested enough). The size of the installation image is 6 GB (x86_64).    <\/p>\n<p>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.       <center><img decoding=\"async\" alt=\"Release of OS Qubes 4.2.0, which uses virtualization for application isolation\" src=\"\/wp-content\/uploads\/2023\/12\/1e19ce23e56ab3674f6dd603f979cb24.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>      <\/p>\n<p>Fedora and Debian package bases can serve as the foundation for forming virtual environments; the community also supports templates for Ubuntu, Gentoo, and Arch Linux.

The user interface is built on Xfce. When a user launches an application from the menu, that application starts in a specific virtual machine.
