Supported Host Operating Systems
Any operating system that can run a supported virtualizer can run Whonix ™, including Windows, macOS, BSD, and Linux. Most users get started by installing VirtualBox on their current operating system and importing the Whonix ™ images. Advanced users may wish to select and boot a host operating system (usually a Linux distribution) dedicated solely to running the Whonix ™ virtual machines.
For the best possible security, users can choose to run Whonix ™ virtual machines on the Qubes platform (Qubes-Whonix ™). Qubes is a Xen-based hypervisor (virtualizer) that runs on the bare metal of the hardware instead of within a host operating system.

Qubes-Whonix ™ System Requirements
Qubes-Whonix ™ does not have any special system requirements over and above Qubes own system requirements. In other words, it is only necessary to fulfill the minimal system requirements for Qubes compatibility.

- This is more secure because an attacker must subvert the hypervisor, which is far more difficult than exploiting a host operating system.
- Custom-Workstation: Self-made builds can be run on any real or virtual hardware, so long as they are behind a Whonix-Gateway ™. Tor Browser binaries are only available for a limited number of platforms (Windows, Linux, BSD and MacOS).
- Unsupported: QEMU
- Unsupported: VMware
- The virtual machine can work with as low as 256 MB RAM, but resource intensive operations like kernel package upgrades that rebuild the initrd might leave the virtual machine in a frozen state. It might run with 196 MB RAM or even less. Experimentation with RAM lower than 256 MB is up to the user; please share your results.
