Virtualbox 4 install on Ubuntu
Since the default Ubuntu repository does not have the current version of VirtualBox (currently 4.1.x) here is the installation procedure via apt-get echo "deb http://download.virtualbox.org/virtualbox/debian $(lsb_release -sc) contrib" | sudo tee /etc/apt/sources.list.d/virtualbox.list wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add - sudo apt-get update sudo apt-get install virtualbox-4.1 To use USB devices on the clients you need to install the Extension Pack from the Oracle Site and install via the File --> Preferences.
