rhevm/ovirt wants the bridge named they way they want it named (i don't
know the reason actual).  I'm not 100% sure on ovirt, but with rhevm they
only want you using that interface for the management of the systems.
However with that name I'd assume that is the case.  Unfortunately, IMO
your best fix is to install the host with ovirtmgmt as the name instead of
breth0.
