VirtualBox Open Source Edition (OSE) is a general-purpose full virtualizer for x86 hardware. By default VirtualBox will be compiled with hardening enabled. That means all binaries will be run suid root, which is the default behaviour of upstream packages. However, you are still able to disable this by passing HARDENING=no to the script. You have to create a vboxusers group, e.g. "groupadd -g 215 vboxusers" and make your user a member of that group. To compile a headless virtualbox pass HEADLESS=yes to the script. To enable the webservice pass WEBSERVICE=yes to the script. This will require gsoap as optional dependency. If you want to build the java bindings, pass JAVA=yes to the script. This will require jdk as optional dependency. If you want to attach VirtualBox to a VDE network you will need vde2. If you want to be able to capture the video output of your virtual hosts you will need libvpx, then pass to the script VPX=yes. For pulseaudio integration pass PULSE=yes to the script. This will require pulseaudio as optional dependency. See README.SLACKWARE for some setup notes. NOTE: This will not build on a stock x86_64 system.
