I have dual monitors and a VM in virtual box with two displays, which gives me two separate windows. Is it possible to make only one of these VirtualBox windows full screen?

If you want to make a VM window to be full screen, you have to install the Guest Additions package in your VM. To do so, you have to:

  1. Once you have launched your VM, in the top menú, select "Devices -> Install Guest Additions". After that, the Guest Additions .iso will be loaded.

  2. You will see the .iso loaded as a CD image. Run it and it will launch the install process in a Terminal. Follow the instructions until the end of the install process.

  3. Reboot your VM.

After that, you will be able to make the VM window full screen, or any size that you want.
