Qubes OS
What Qubes OS is
Qubes OS is a free, open-source Linux operating system that separates activities into isolated workspaces called qubes. It uses the Xen hypervisor to keep websites and services apart, and allows different operating systems, including Linux distributions and Windows programs, to run in separate workspaces. Whonix is integrated for internet use through the Tor network. Qubes OS 4.3.2 is listed as the latest stable release. Minimum hardware includes a 64-bit Intel or AMD processor with virtualization and IOMMU support, 6 GB of RAM, and 32 GB of free storage. Documentation recommends 16 GB of RAM, 128 GB of storage, Intel integrated graphics, and a processor receiving microcode updates. Meeting requirements does not guarantee installation or operation, and installation inside another virtual machine is not recommended. Download verification uses a detached PGP signature and signing key. The project publishes security advisories and directs questions to its community forum.
