添加网卡在控制端创建，也可以在dashboard创建，下面我们在命令添加
查看network，添加ip用到
test@controller:~$ openstack network list +--------------------------------------+--------------+--------------------------------------+ | ID | Name | Subnets | +--------------------------------------+--------------+--------------------------------------+ | 0cbeef7b-9014-43fe-9103-66da4c03f54a | vxlan_172.30 | 39667cc6-503c-4b65-a4e5-17c116763502 | | 993bbc0a-fed2-4186-bb7d-64644c9ad8bf | public | 46a17ab6-c67d-4be3-b1cb-4efe6aeb4fef | +--------------------------------------+--------------+--------------------------------------+
确认子网
test@controller:~$ openstack subnet list
+--------------------------------------+-----------------+--------------------------------------+---------------+
| ID | Name | Network | Subnet |
+--------------------------------------+-----------------+--------------------------------------+---------------+
| 39667cc6-503c-4b65-a4e5-17c116763502 | subnet_172.30.0 | 0cbeef7b-9014-43fe-9103-66da4c03f54a | 172.30.0.0/24 |

+--------------------------------------+-----------------+--------------------------------------+---------------+
查看已有的接口地址，以便检测需要添加的网卡的ip是否会冲突

创建指定ip的接口，注意不要冲突，当然你也可以不需要指定IP，DHCP自己分配
语法： openstack port create name --network networkname --fixed-ip subnet=subname,ip-address=X.X.X.X
注意后面这里的--fixed-ip到结尾是一体的，2个key value 详情查看帮助 openstack port create
test@controller:~$ openstack port create 172.30.0.88 --network vxlan_172.30 --fixed-ip subnet=subnet_172.30.0,ip-address=172.30.0.88

我们拿一个cirros虚机测试看看，发现eth1没有IP
编辑网卡配置信息，自动获取就行了。
重启，然后就发现啦
卸载网卡 nova interface-detach serverid portid
test@controller:~$ nova interface-detach 5680b384-7449-4a63-a874-9991f01dde4e 70223854-45a1-44c7-aeb9-8d7be2328948
删除网卡 openstack port delete portid
test@controller:~$ openstack port delete 70223854-45a1-44c7-aeb9-8d7be2328948
