openstack kilo 配置dvr
配置neutron-server编辑/etc/neutron/neutron.conf
router_distributed = True 编辑/etc/neutron/plugins/ml2/ml2_conf.ini,添加l2population
mechanism_drivers = openvswitch,l2population 配置network节点
配置L2,编辑/etc/neutron/plugins/ml2/ml2_conf.ini
mechanism_drivers = openvswitch,l2population
...
l2_population = True
enable_distributed_routing = True
arp_responder = True 配置L3,编辑/etc/neutron/l3_agent.ini
agent_mode = dvr_snat 配置计算节点
配置L2 agent
mechanism_drivers = openvswitch,l2population
...
l2_population = True
enable_distributed_routing = True
arp_responder = True 配置L3 agent，配置参数除agent_mode,其余和网络节点一致
agent_mode = dvr 配置metadata
配置方式和network一致，在我的环境中，由dhcp提供metadata，就没有在计算节点上再配置metadata 服务
