extension_drivers = port_security
#註釋以下幾行
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
enable_ipset = True

3、修改配置檔案/etc/neutron/l3_agent.ini

# line 17: add
interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver
# line 100: add ( it's OK with no value (set later if need) )
external_network_bridge =

4、修改配置檔案/etc/neutron/dhcp_agent.ini

# line 17: add
interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver
# line 32: uncomment
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
# line 41: uncomment and change
enable_isolated_metadata = True
5、修改配置檔案/etc/neutron/metadata_agent.ini
# line 22: uncomment and specify Nova API server
nova_metadata_ip = 172.16.100.10
# line 34: uncomment and specify any secret key you like
metadata_proxy_shared_secret = metadata_secret

6、修改配置檔案/etc/neutron/plugins/ml2/ml2_conf.ini

[ml2]
type_drivers = flat,vlan,gre,vxlan
tenant_network_types =
mechanism_drivers = openvswitch,l2population
extension_drivers = port_security
# line 247: uncomment and add
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
# end line: uncomment
enable_ipset = True

7、建立連結

# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini 

8、重啟服務

# systemctl start openvswitch 
# systemctl enable openvswitch 

9、建立網橋

# ovs-vsctl add-br br-int

# for service in dhcp-agent l3-agent metadata-agent openvswitch-agent; do
systemctl start neutron-$service
systemctl enable neutron-$service
done
