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 and Fedora. 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 and Tor. 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-14 -- 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. 
For a more in-depth consideration of Qubes-Whonix advantages, see: Why use Qubes over other Virtualizers?
For major TemplateVM and AppVM operations, refer to the following guides:
- Install Qubes-Whonix
- Update Qubes-Whonix
- Update Tor Browser
- Reinstall Qubes-Whonix TemplateVMs
- Uninstall Qubes-Whonix TemplateVMs
- Install and update software in dom0
- Backup, restore and migrate VMs
For improved security and anonymity after installing Qubes-Whonix, refer to the following guides:
- Post-installation security advice
- How to use Tor Bridges
- Multiple Whonix-Workstations
- Qubes-Whonix Security
Before seeking personal support, please first search for the issue and a possible, documented solution. In many cases the issue can be solved by inspecting the phabricator issues tracker, reading Whonix guides/documentation, conducting web searches, and examining past support requests.
If a search yields no results, support requests should be directed to the most appropriate forum:
- Qubes: Qubes Support
- Qubes-Whonix-specific: Whonix Qubes Forum
- Whonix, Debian and Tor: Whonix Support
- The only limitation on the number of possible VMs is available disk space.
