Logs are too general.

let me give you a few leads.

1. Check the mysql connection string inside /etc/neutron/neutron.conf and see if it is valid.
2. Check the keystone_authtoken section inside the same file and verify if they are correct and if the specified user/tenant(neutron/service) is available in keystone.
3. See if the neutron-server is running. If yes see if it is responsive . may be do a 'neutron agent-list'. of course after setting the auth credentials in environment variables.
4. See if all the agents (openvswitch/l3/dhcp) are in good state.

If you see any of your agents or if the neutron-server itself is down please share your config file and log while restarting.

Subject: [Openstack] help with neutron

Hi, I try to config ryu controller with openstak, and got a  problem:
# sudo ovs-ofctl dump-flows br-int
NXST_FLOW reply (xid=0x4):
no other flow entries

here is some info, and I think the main problem is with neutron-server
any help ?
thanks
