If you check http://libvirt.org/formatdomain.html#elementsNICS then it is not 
much clear if the type bridged is more suitable or ethernet cause the bridged 
section says: "This assumes there is a bridge device on the host which has one 
or more of the hosts physical NICs enslaved" and which is what vbox is doing 
if i have got the interpretation right.

so frankly even thought the patch looks sane I am not sure about the 
terminology there and am confused as well. Maybe someone with greater 
knowledge in the networking area of libvirt should comment on it.

Pritesh
