In the bug you filed requested this feature, you said that you want
this so that you can make oVirt configure bridging behind libvirts
back with Quantum. As explained in the bug, this is a really bad way
todo this & should not be required - OpenStack Nova demonstrates you
can do the right thing wrt Quantum using exisiting libvirt config.
So I'm not inclined to support this disconnected mode.
