With this parameter you shouldn't see the interface listed in setup host networks of the host gui. The concept came out last year when I posted a question related to OVN and Marcin Mirecki kindly answered about it. See here and the whole thread: https://lists.ovirt.org/pipermail/users/2017-February/079772.html Marcin, possibly you can add something for this particular need? HIH, Gianluca
