Introduction to virtual machines

It is sometimes convenient to be able to run Tails without having to restart your computer every time. This is possible using virtual machines.

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 guest which appears in a window on the host operating system.

When running Tails in a virtual machine, you can use most features of Tails from your usual operating system and use both in parallel without the need to restart the computer.

This is how Tails looks like when run in a virtual machine on Debian using GNOME Boxes:

We do not currently provide a solution for running a virtual machine inside a Tails host. See #5606.

Security considerations

Running Tails inside a virtual machine has various security implications. Depending on the host operating system and your security needs, running Tails in a virtual machine might be dangerous.

  • Both the host operating system and the virtualization software are able to monitor what you are doing in Tails.

    If the host operating system is compromised with a software keylogger or other malware, then it can break the security features of Tails.

    Only run Tails in a virtual machine if both the host operating system and the virtualization software are trustworthy.

  • Traces of your Tails session are likely to be left on the local hard disk. For example, host operating systems usually use swapping (or paging) which copies part of the RAM to the hard disk.

    Only run Tails in a virtual machine if leaving traces on the hard disk is not a concern for you.

This is why Tails warns you when it is running inside a virtual machine.

The Tails virtual machine does not modify the behaviour of the host operating system and the network traffic of the host is not anonymized. The MAC address of the computer is not modified by the MAC address spoofing feature of Tails when run in a virtual machine.

Virtualization solutions

To run Tails inside a virtual machine, you need to have virtualization software installed on the host operating system. Different virtualization software exist for Linux, Windows, and macOS.

The following list includes only free software as we believe that this is a necessary condition for it to be trustworthy. See the previous warning and our statement about free software and public scrutiny.

Proprietary virtualization software solutions exist such as VMWare but are not listed here on purpose.

  • VirtualBox is available for Linux, Windows, and Mac. Its free software version does not include support for USB devices and does not allow to use a persistent volume.

    See the corresponding documentation.

  • GNOME Boxes is available for Linux. It has a simple user interface but does not allow to use a persistent volume.

    See the corresponding documentation.

  • virt-manager is available for Linux. It has a more complex user interface and allows to use a persistent volume, either by:

    • Starting Tails from a USB stick.
    • Creating a virtual USB storage volume saved as a single file on the host operating system.

    See the corresponding documentation.
