I believe it is probably generally harder to break out of a virtual machine than root a Linux distro, like Tails, because hypervisors have a more limited attack surface compared to a full monolithic OS.

If you use Qubes, then it is infinitely harder to root the host system.


Can you describe the scenario how can somebody potentially break out
of the virtual machine and root the host system, if VM is wired to
connect only through tor?

Some VM breakout scenarios:

- Hypervisor vulnerability

- Trojaned hypervisor

- Side channels
