That does look ok: I have an essentially equivalent local.conf:

...
ENABLED_SERVICES+=,-n-net
ENABLED_SERVICES+=,q-svc,q-agt,q-dhcp,q-l3,q-meta,q-metering,tempest

I don't have 'neutron' specifically enabled... not sure if/why that 
might make any difference tho. However instance launching and ip address 
assignment seem to work ok.

However I *have* seen the issue of instances not getting ip addresses in 
single host setups, and it is often due to use of virt io with bridges 
(with is the default I think). Try:

nova.conf:
...
libvirt_use_virtio_for_bridges=False
