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 virtualbox without the Qt4 GUI pass QT4=no to the script. To enable the webservice pass WEBSERVICE=yes to the script. This will require the optional dependency gsoap. If you want to attach VirtualBox to a VDE network you will need vde2. See README.SLACKWARE for some setup notes. NOTE: This will not build on a stock x86_64 system.
