With virtual machines, it is possible to run Tails inside a *host* operating system (Linux, Windows, or macOS). A virtual machine emulates a real computer and its operating system, called a *guest*, which appears in a window on the *host* operating system.

To run Tails inside a virtual machine, you need to have virtualization software installed on the host operating system. Different virtualization software exists for Linux, Windows, and macOS. Unfortunately, we only know of virtualization solutions for Linux that work well with Tails.
