  I'm not entirely sure if you honestly asking or just trying to make me
realize how many variables are involved in such support.  I will assume the
former.

  I have team0 interface of two physical NICs.  I'd like to have this team0
interface attached to particular VM.  That would mean bridged network I suppose.
There are no VLANs in my setup.
  To be clear, I am able to tear down this setup and revert to old-school bond.
I'd prefer not to – it needs some downtime to reconfigure and validate.
So now I'm against the question: what will require more work from me,
reconfiguring network or making ovirt recognize basic team0.
