- Executando Tails em uma máquina virtual
Às vezes é conveniente poder executar o Tails sem precisar reiniciar o computador todas as vezes. É possível fazer isso usando .
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.
When running Tails in a virtual machine, you can use most features of Tails from your usual operating system, and you can use both Tails and your usual operating system in parallel, without the need to restart the computer.
No momento nós não fornecemos uma solução para executar uma máquina virtual dentro de um hospedeiro Tails.
This is how Tails looks when run in a virtual machine on Debian:
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.
Tanto o sistema operacional hospedeiro quanto o software de virtualização são capazes de monitorar o que está sendo feito no Tails.
Se o sistema operacional hospedeiro estiver infectado por um software de captura de teclado (keylogger), ou outro malware, então poderá quebrar as funcionalidades de segurança do Tails.
Only run Tails in a virtual machine if both the host operating system and the virtualization software are trustworthy.
É bem possível que sejam deixados traços da sua sessão do Tails no disco rígido local. Por exemplo, os sistemas operacionais hospedeiros geralmente usam um espaço de troca (ou paginação), onde parte da memória RAM é copiada para o disco rígido.
Only run Tails in a virtual machine if leaving traces on the hard disk is not a concern for you.
É por isso que o Tails mostra uma advertência quando é executado em uma máquina virtual.
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 anonymization 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 exists for Linux, Windows, and macOS.
We only mention Free Software, because we believe that it is a necessary condition to be trustworthy. Proprietary virtualization software exist, such as VMWare, but is not listed here on purpose.
We are not recommending VirtualBox anymore because only basic functionalities of Tails work in VirtualBox, for example, the display size is limited to 800×600 pixels.
GNOME Boxes is only available on Linux. It has a simpler user interface than virt-manager but does not allow to use a Persistent Storage.
virt-manager is only available on Linux. It has a more complex user interface than GNOME Boxes but allows to use a Persistent Storage, either by:
- Iniciando o Tails a partir de um dispositivo USB.
- Criando um volume de armazenamento USB virtual salvo como um único arquivo no sistema operacional hospedeiro.
