VirtualBox: how to extend view in the graphic mode?

I have CentOS-5.6 running on t开发者_Python百科he Oracle's VirtualBox. I would like to know if it possible to have it in full-screen size when running X Window applications. I know such feature is available with VMWare player (you need to download additional vmware tools).

Thanks.

You can follow the instructions on VirtualBox's site for installing Guest Additions. That should allow the screen to automatically resize when you fullscreen VirtualBox. In addition, you may have to adjust the screen resolution in X afterwards if Guest Additions alone don't solve your problem.

You need Virtual Box guest extensions.

In order to install them you first need the RPMForge repository added for yum, follow these instructions:

Then run this command in a terminal:

yum install dkms
