some workaround when using kvm virtualization

To run a terminal, i was using Ctrl + Alt + T to open a terminal in the host OS. Now that I am inside a guest OS, running the command would render a terminal 'outside' of the guest OS, and I cant exit the terminal.

Then I find out about Ctrl Alt F1 to switch to the virtual terminal on the host.

Then I can now access the overlay terminal and execute the exit command.
