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 boot a host operating system (usually a Unix variant) 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
Minimum (Qubes 4.X)
- 4 GB RAM.
- 32 GB disk space.
- A 64-bit Intel or AMD processor -
- A fast SSD - strongly recommended.
- Intel IGP - strongly preferred.
- TPM with proper BIOS support - required for Anti Evil Maid [archive].
- 16 GB+ RAM minimum. 32 GB+ for power users. 
- A non-USB keyboard or multiple USB controllers to enable creation of a USB VM [archive]. 
- Interrupt remapping - this helps resist potential (hypothetical) attacks coming from compromised driver domains like
Before purchasing any hardware specifically for Qubes, consider Qubes Certified Hardware [archive], Qubes Hardware Testing [archive] or at least the hardware compatibility list (HCL) [archive] for suitable models. Without referring to any of these, there is a chance that a computer without the above specifications will be incompatible with Qubes.
Also note the fairly priced Insurgo PrivacyBeast X230 [archive] is the first custom, refurbished laptop to exceed all Qubes hardware certification requirements.  For detailed specifications and pricing, see: Insurgo PrivacyBeast X230 Laptop - QubesOS Certified & preinstalled - Single Order [archive].

- 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.

- This is required for running HVM domains [archive], such as Windows-based AppVMs.
- Users report problems in creating DisposableVMs and running multiple VMs in parallel with only 4 GB RAM. 8 GB RAM is nearly exhausted with Qubes-Whonix ™ VMs running in parallel with the

- Binary-blob-free Coreboot initialization, including native graphic initialization.
- Heads provides an Anti-evil Maid (AEM) firmware solution and protects against malicious interdiction.
- Intel ME is neutered and unnecessary modules involved in main CPU initialization have been deleted.
- Ships with Qubes OS pre-installed (with full-disk encryption), with the final disk encryption key being regenerated when first powered on by the buyer.
