Well phooey: 987 if network_ref['multi_host']: 988 _add_dhcp_mangle_rule(dev)
The mangle rule is only added my nova-network in multihost mode. Can you verify whether or not adding the rule on the compute or network node fixes it? That way we can either remove the check on multi_host or add it in plug_vif on the compute host.
