Qubes-Whonix ™ Overview
In this configuration Whonix ™ runs on top of Qubes inside virtual machines (VMs), just like any other OS on the same platform (Fedora, Debian, Arch Linux and so on).
The Qubes bare-metal hypervisor is based on Xen [archive] and Fedora [archive]. Via hardware support like VT-x, VT-d and TXT, Qubes has implemented a strict security-by-isolation architecture. Hardware controllers and multiple user domains (qubes) are isolated using separate VMs that are explicitly assigned different levels of trust, yet the desktop experience is user-friendly and well-integrated.
Whonix ™ is based on Debian [archive] and Tor [archive]. The design provides a two-VM, split security architecture: an isolated Whonix-Gateway ™ (ProxyVM;
sys-whonix) for complete routing of traffic over Tor; and Whonix-Workstation ™ (AppVM;
anon-whonix) for all desktop applications, which serves as a tailored OS environment for Tor-based privacy/anonymity.
To use Qubes-Whonix ™, Qubes must first be installed as a hypervisor on the physical host computer, followed by installation of the two separate Whonix ™ TemplateVMs --
whonix-ws-15 -- on top of Qubes. From this point, the Whonix ™ TemplateVMs can be used for customization and creation of multiple Whonix-Gateway ™ ProxyVMs and Whonix-Workstation ™ AppVMs, enabling enhanced compartmentalization of user activities for better privacy.
