My recommendation is that you just set up non-NM-controlled static
network using your public /32.  Then the hosted-engine --deploy process
should take that config and apply it to ovirtmgmt bridge.  At least,
that's what happened for me when I did it.  I don't think you need to
set up the ovirtmgmt bridge manually.

As for the /29 -- don't worry about it now, that would be a routing
issue you can apply later.  Is it the same network as the /32?  Or is it
a different network?
