I installed packstack all in one with following manual on physical server CentOS Linux 7 (Core)
But the instance i launch cirros don't get ip, not private and not public
openstack.redhat.com/Neutron_with_existing_external_network
openstack.redhat.com/Running_an_instance_with_Neutron
I deleted the public network and created a new one with following command

neutron subnet-create --name public_subnet --enable_dhcp=False --allocation-pool=start=172.16.7.1,end=172.16.7.20  --gateway=172.16.1.1 public 172.16.7.0/16

Here is the configuration on my physical server

cat /etc/sysconfig/network-scripts/ifcfg-br-ex
DEVICE=br-ex
DEVICETYPE=ovs
TYPE=OVSBridge
BOOTPROTO=static
IPADDR=172.16.4.250
NETMASK=255.255.0.0
GATEWAY=172.16.1.1
DNS=172.16.1.121
ONBOOT=yes

cat /etc/sysconfig/network-scripts/ifcfg-enp3s0f0
HWADDR=68:B5:99:CD:E6:24
NAME=enp3s0f0
UUID=d6f2025c-780d-4cc5-b3f4-84a8d3dc5e5a
ONBOOT=yes
TYPE=OVSPort
DEVICETYPE=ovs
OVS_BRIDGE=br-ex

Here are some log parts from cirros instance

are you sure i need to run the ovs, because the installation command that i run (from rdo site) is packstack --allinone --provision-all-in-one-ovs-bridge=n

how do you restart neutron service i rebooted the machine but it didn't help, still no ip

Openstack-nova-network is inactive (disabled on boot) as well as neutron-lbaas-agent is inactive (disabled on boot . same issue I have faced earlier (vm-ip) . I reinstalled ovs and restarted all the neutron services.I worked for me. Hope it will work for you also.
