→VirtualBox Linux Host Requirements
* '''SDL''' - Version 1.2.7 or newer of the ''libsdl'' graphics library must be installed.
Another optional package is Dynamic Kernel Module Support (DKMS). As part of the installation process, VirtualBox installs two kernel modules (vboxdrv and vboxnetflt) onto the host system. These modules must match the running Linux kernel at all times for VirtualBox to function. This can be an issue when the host kernel is updated at any point in the future. Whilst not required to install and run VirtualBox, the presence of the DKMS package will ease the transition to future kernel updates. When installed, DKMS ensures that the VirtualBox kernel modules are rebuilt automatically when the Linux kernel is updated. Without this package, the VirtualBox kernel module will need to be rebuilt manually each time a kernel update is applied to the host system.
== Downloading VirtualBox for Linux ==
The binary version of VirtualBox, pre-packaged for a wide variety of
Linux distributions, may be downloaded from the [http://www.virtualbox.org/wiki/Linux_Downloads VirtualBox web site]. Select the package which matches your Linux distribution (Fedora, Ubuntu, Red Hat, CentOS etc) and host architecture ( i386 or AMD64) and download the archive to a suitable temporary location . If your Linux distribution is not listed download the appropriate archive for the ''All distributions'' option.
