We'd very much like to see VirtualBox suported as a driver in libvirt
because its a pretty popular open source virt technology and there have
been quite a few feature requests from users for it to be included.

I see no problem in supporting RDP as an option for VirtualBox. We
already have two possible <graphics> tags

  <graphics type='sdl' display=":0.0" xauth="/root/.Xauthority"/>


  <graphics type='vnc' listen='' port='5901' autoport='yes'/>

So we can easily add another option for RDP, which I'd guess would
be very similar to the VNC options, since its another client/server
network based system

  <graphics type='rdp' listen='' port='5901' autoport='yes'/>
