2 Installation details 2.2 Installing on Mac OS X hosts 2.2.1 Performing the installation For Mac OS X hosts, VirtualBox ships in a disk image (dmg) file. Perform the following steps: 1. Double-click on that file to have its contents mounted. 2. A window will open telling you to double click on the VirtualBox.mpkg installer file displayed in that window. 3. This will start the installer, which will allow you to select where to install VirtualBox to. After installation, you can find a VirtualBox icon in the “Applications” folder in the Finder. 2.2.2 Uninstallation To uninstall VirtualBox, open the disk image (dmg) file again and double-click on the uninstall icon contained therein. 2.2.3 Unattended installation To perform a non-interactive installation of VirtualBox you can use the command line version of the installer application. Mount the disk image (dmg) file as described in the normal installation. Then open a terminal session and execute: sudo installer -pkg /Volumes/VirtualBox/VirtualBox.mpkg \ -target /Volumes/Macintosh\ HD 2.3 Installing on Linux hosts 2.3.1 Prerequisites For the various versions of Linux that we support as host operating systems, please refer to chapter 1.4, Supported host operating systems, page 13. You will need to install the following packages on your Linux system before starting the instal- lation (some systems will do this for you automatically when you install VirtualBox): • Qt 4.4.0 or higher • SDL 1.2.7 or higher (this graphics library is typically called libsdl or similar). Note: To be precise, these packages are only required if you want to run the VirtualBox graphical user interfaces. In particular, VirtualBox, the graphical VirtualBox manager, requires both Qt and SDL VBoxSDL, our simplified GUI, requires only SDL. By contrast, if you only want to run VBoxHeadless, neither Qt nor SDL are required. 31
