This is pretty easy:
- Open VirtualBox
- In the main menu, open the first tag (file) and select the fourth option (Configuration / Preferences). In my VirtualBox, you can go directly there with Ctrl + G.
- Once you are in the "Configuration" menu, in the left pane, select the one where the image of the world is displayed (Language).
- Select your preferred language.
