5. 启动

systemctl enable neutron-openvswitch-agent.service neutron-l3-agent.service
systemctl start neutron-openvswitch-agent.service neutron-l3-agent.service

• 下载和配置（compute1节点）

1. 下载
   yum install -y openstack-neutron-openvswitch
2. 配置
   vi /etc/neutron/plugins/ml2/openvswitch_agent.ini

[ovs]
tunnel_bridge = br-tun
local_ip = 192.168.0.203
integration_bridge = br-int

[securitygroup]
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
enable_security_group = True

3. 启动

systemctl enable neutron-openvswitch-agent.service
systemctl start neutron-openvswitch-agent.service
