Qubes OS Templates: Secure, Efficient VM Management
2025-01-13

Qubes OS utilizes a template system for managing virtual machines, enhancing security, storage efficiency, and boot speed. Each template shares its root filesystem, with applications running and storing data within qubes. Updating a template automatically updates all qubes based on it after a restart. Software should be installed in templates, not app qubes. Qubes offers templates based on Fedora, Debian, and more, plus community templates. Users can install, update, uninstall, or switch templates via command-line or GUI tools. Uninstall warnings are normal. Switching templates requires updating all qubes based on the old template. Template security is crucial; install software only from trusted sources.
