[libvirt] Some help in Starting up

Hi everyone! I hope you bear with me, and I would be grateful for that, as I am very new to all this... I want to develop for libvirt and want to specifically work on it for the VirtualBox domain. The problem is I have no idea how to set up my development environment... I have a ubuntu 64 bit machine with me, with The latest Virtual box installed (from the official site), and git already installed. Now what am I suposed to do? get libvirt code from the git repository? if that is so then what would be the next step? -- Regards, Arslan Waqar.
