[ovirt-users] ovirtmgmt manual bridge cannot be used in ovirt 4.0

[Charles Kozler]

Thats what I used to do as well then on oVirt 4 it started screwing with
the the bond as well so I ended up just dumbing it down and figured using
the UI after the fact would be OK. I cant remember exactly what would
happen but it would be stupid little things like routing would break or
something.
