在OpenStack中默认由于安全组策略限制，云主机只响应自己的iP地址请求，如果需要做HA，可以用以下两种方式实现
1、 增加allow_address_pairs属性
# neutron port-list |grep 10.xxx.51.50
# neutron port-show cff5866e-f288-4614-8778-665795207e0f

2、 关闭neutron port的安全组特性
# neutron port-update --no-security-groups $port_id # neutron port-update $port_id --port-security-enabled=False
