Installing Ubuntu under VirtualBox

Ubuntu 9.10 in VBox 3.1:

• Install VBox, download Ubuntu ISO, mount iso, create new machine (first starting from CD-ROM, installation manual!).
• Install Guest additions inside Ubuntu: a) Host menu Devices, Install Guest additions. b) Open terminal, type "sudo /media/cdrom0/VBoxLinuxAdditions-x86.run". 2. Fixing Screen color issue: Increase graphics mem to 16 MB, allow 3d, but then disable in ubuntu appearances: effects. (Note: VBox 3.1.0 had problems with Ubuntu Screen sizing and color. Problems disappear when Updating to VBox 3.1.2 and reinstalling Guest additions inside Ubuntu).
• Add additional repositories as of https://help.ubuntu.com/community/Medibuntu

To hide the superfluous menu and status bar of the VBox window around Ubuntu, open CMD,

cd C:\Program Files\Sun\VirtualBox
VBoxManage setextradata global GUI/Customizations noMenuBar,noStatusBar
# (instead of global one can put the machine name)
# getextradata for machine ubuntu:
VBoxManage getextradata ubuntu enumerate
