connecting to virtualbox with libvirt

[Gary Scarborough <linuxgoblin@xxxxxxxxx>]

I am trying to connect to the virtualbox hypervisor through libvirt.  If I am doing it correctly, 

virsh -c vbox:///session

should get me connected.  I am on F14 64 bit.  I tried this with both vbox 3.2 and 4.02.  I keep getting the following error:

error: no connection driver available for vbox:///session.

What am I missing?

Thanks,

Gary
