Hi  All,
 I try to use l2 gateway. Use one node install devstack, and another node as gateway installing ovs 2.5.0

The devstack running neutron-l2gateway-agent and neutron-server with l2gateway plugin.
file /etc/neutron/l2gateway_agent.ini  looks like, "node-82" is the gateway node hostname.
[DEFAULT]
[ovsdb]
ovsdb_hosts = node-82:10.254.9.82:8802   

node-82 running ovs listening to remote port 8802. 
ovsdb-server /etc/openvswitch/conf.db -vconsole:emer -vsyslog:err -vfile:info --remote=punix:/var/run/openvswitch/db.sock --remote=ptcp:8802 --private-key=db:Open_vSwitch,SSL,private_key --certificate=db:Open_vSwitch,SSL,certificate --bootstrap-ca-cert=db:Open_vSwitch,SSL,ca_cert --no-chdir --log-file=/var/log/openvswitch/ovsdb-server.log --pidfile=/var/run/openvswitch/ovsdb-server.pid --detach --monitor
ovs-vswitchd unix:/var/run/openvswitch/db.sock -vconsole:emer -vsyslog:err -vfile:info --mlockall --no-chdir --log-file=/var/log/openvswitch/ov-vswitchd.log --pidfile=/var/run/openvswitch/ovs-vswitchd.pid --detach --monitor
devstack node could config node-82 ovs bridge successfully.

Then execute:
neutron l2-gateway-create gw1 --device name=node-82,interface_names=enp7s0f1         result: works well, and db add this info to table l2gateways.
 neutron l2-gateway-connection-create gw1 net1 --default-segmentation-id=100             result: returns "L2 Gateway Device node-82 could not be found."


Is ovs could be treated as gateway?
The config file has something wrong?

Best regards,
Yujie
