Sun Virtualbox Questions

I install Virtualbox on my newly build Window 7 Pro laptop.

Than I installed both Ubuntu and Window Server 2003 on it and is running fine.

But for some reason, the screen is really small and unable to make it full screen display. Any clue?

Also, I am using virtualbox in hope to test applications. I have build a base template and I want to make copies of these OS so that I can test application and delete it afterward. How do I make copies of these virtualize OS within virtualbox?

You need to change the display resolution of the VM

Install the Guest Additions (either through the mount of the Virtual Guest Additions CD or through the menu Device choices). After reboot of your virtual machine, you can use the Host key+F or the Host key + G to go to full screen or Grow respectively. You need the Guest Additions video driver loaded.

As far as your 2nd question, use the snapshots feature from your VirtualBox guest (Machine Menu or Host + S - Host key by default is your Right Ctrl key). Take a snapshot before installing your test applications. then remove your 'current state' which rolls back to the previous snapshot through the VirtualBox console application.

PS. You can also change resolution to match screen size from within your host. Failing that, make sure the Guest Additions are installed ;)
