Qubes OS is a security-oriented, Fedora-based desktop Linux distribution whose main concept is "security by isolation" by using domains implemented as lightweight Xen virtual machines. It attempts to combine two contradictory goals: how to make the isolation between domains as strong as possible, mainly due to clever architecture that minimises the amount of trusted code, and how to make this isolation as seamless and easy as possible.
Joanna Rutkowska has announced the launch of Qubes OS 3.1, a new stable release of the Qubes operating system which enforces strong isolation between tasks. Version 3.1 of the security-oriented project features a new management system that centrally controls Qubes configuration: "The major new architectural feature of this release has been the introduction of Qubes Management infrastructure, which is based on popular Salt management software. In Qubes 3.1 this management stack makes it possible to conveniently control system-wide Qubes configuration using centralized, declarative statements. Declarative is a key word here: it makes creating advanced configurations significantly simpler (the user or administrator needs only to specify what they want to get, rather than how they want to get it). This has already allowed us to improve our installation wizard (firstboot) so that it now offers the user ability to easily select various options to pre-create some useful configurations, such as e.g. Whonix or USB-hosting VMs.
