查看已有的网络接口(对应虚拟机网卡)

# . admin-openrc

admin权限查看能够多看到租户id tenant_id

普通租户是看不到租户id的

使用admin权限创建一个网络接口，可以指定租户，指定ip地址，以及指定对应的网络

# . admin-openrc   
# neutron port-create --tenant-id 9c658f84358140378e637f0b27c7ca57 --fixed-ip ip_address='172.16.40.104' provider
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.

将新创建的port连接到虚拟机上

# nova list
+--------------------------------------+------------+---------+------------+-------------+------------------------+
| ID                                   | Name       | Status  | Task State | Power State | Networks               |
+--------------------------------------+------------+---------+------------+-------------+------------------------+
| eddcb46e-eac5-4403-83a8-1f0d8ac34439 | hadoop-4   | ACTIVE  | -          | Running     | provider=172.16.40.134 |
| 06a43249-9258-409e-b791-541396771a9d | zxq-3      | ACTIVE  | -          | Running     | provider=172.16.40.108 |
+--------------------------------------+------------+---------+------------+-------------+------------------------+

添加连接，如果不指定port-id，则会自己创建一个新的

# nova interface-attach --port-id 5e993bfd-219b-4e0e-9173-721e072e7342 eddcb46e-eac5-4403-83a8-1f0d8ac34439
# nova interface-list eddcb46e-eac5-4403-83a8-1f0d8ac34439
+------------+--------------------------------------+--------------------------------------+---------------+-------------------+
| Port State | Port ID                              | Net ID                               | IP addresses  | MAC Addr          |
+------------+--------------------------------------+--------------------------------------+---------------+-------------------+

+------------+--------------------------------------+--------------------------------------+---------------+-------------------+

分离接口

# nova interface-detach eddcb46e-eac5-4403-83a8-1f0d8ac34439 00401677-543c-4834-9f30-d25e179e88a0
# ping 172.16.40.104
PING 172.16.40.104 (172.16.40.104) 56(84) bytes of data.
64 bytes from 172.16.40.104: icmp_seq=1 ttl=64 time=3.11 ms

可以ping通，添加指定ip正常。
