neophy,
It seems like there are left overs that fuel was using in the config
that would not be present when you installed neutron fresh. I'd
compare the config files and start backing out bits you dont need. I'd
start with the lines refrencing br-int, you dont need them on nodes
that aren't using the ovs agent.
Poke me on IRC if you need more help
