VirtualBox: guest OS in full screen real

When a virtualized guest operating system (guest) with VirualBox often the case that it is impossible to use this system to full screen (full screen mode ). Whether in a window or full screen all we have is a square where you see the desktop of the guest gaming really too small to be used easily and sometimes fruitful.

The solution to this problem is relatively simple, use so-called VirtualBox Guest Additions and it is divided into few steps:

• visit the download page of VirtualBox ;


• choose the folder for your version of VirtualBox, 3.2.8 for example;


• VBoxGuestAdditions_X.YZiso download the file, where XYZ is the version selected in the previous step (in my example, 3.2.8);


• VBoxGuestAdditions_X.YZiso burn it onto a CD (possibly writable) using any burning program for Windows or Linux;


• launch the guest OS we want fixare;


• insert the cd already burned into your optical drive of our PC


• explore the cd and identify the file that corresponds to our guest system (Windows, Linux, Linux 32bit or 64bit), for example VBoxLinuxAdditions-amd64.run ;


• execute the file system corresponding to our guest, for example by entering the terminal (after being placed in the directory of the CD) sudo sh-VBoxLinuxAdiitions amd64.run request to provide the superuser password (for Windows guest systems simply click twice on the file. exe)


• at the end of the script, turn off the virtual machine and close VirualBox.

On reboot you should be able to use the guest in full screen.
