Once installed, you can run VirtualBox from your GNOME menu under System Tools. Or, if you installed onto a server system with no graphical system, then launch it from your remote Linux system by connecting via SSH ($ ssh -X hostname) and typing, virtualbox &, at a user prompt.
If you're running Windows, connect via an SSH client with X11 forwarding on and use an X server like Xming to view remote graphical programs.
If you need more assistance with making the connection from your remote system or installing VirtualBox 4.1, please use the Talkback area.
Tell me what you think of VirtualBox 4.1, if you can pull yourself away from it long enough to do so.
