neutron 给虚机分配keepalived vip

目的: 需要要使用keepalived做高可用，给虚机分配vip使用

创建vip port

#neutron port-create {{NETWORK_NAME}} --name test-vip

放行虚拟机端口对应的allowed-address-pairs

#neutron port-list --device_id={{VM1_UUID}}

#neutron port-list --device_id={{VM2_UUID}}

#neutron port-update {{VM1_PORT_UUID}} --allowed-address-pairs type=dict list=true ip_address=0.0.0.0/0

#neutron port-update {{VM2_PORT_UUID}} --allowed-address-pairs type=dict list=true ip_address=0.0.0.0/0
