[ovirt-users] How to change host networks?

[Roderick Mooi]

Good day

Can anyone assist me with this please? - I'm starting over and would like
to know how to change network settings correctly post-installation. Must I
only change it in the GUI and then sync to have the changes applied to the
hosts? Does this work for the management network?

Thanks,

Roderick
