Oracle VirtualBox ships with six front ends for sysadmins and sysmans to chose from !

• VirtualBox – the Qt GUI front end implementing the manager and running VirtualBox VMs.
• VBoxManage - a less user-friendly but more powerful alternative.
• VBoxSDL – a simple graphical front end based on the SDL library.
• VBoxHeadless – a VM front end which does not directly provide any video output and keyboard/mouse input, but allows redirection via VirtualBox Remote Desktop Extension.
• vboxwebsrv – the VirtualBox web service process which allows for controlling a VirtualBox host remotely.
• VirtualBox Python shell – a Python alternative to VBoxManage.
