openstack 为虚机添加网口

创建 subnet  
neutron subnet-create public PUBLIC_NETWORK_CIDR --name public 
  --allocation-pool start=START_IP_ADDRESS,end=END_IP_ADDRESS
  --dns-nameserver DNS_RESOLVER --gateway PUBLIC_NETWORK_GATEWAY

先查找tenant 

[root@controller01 ~]# openstack project list
+----------------------------------+---------+
| ID | Name |
+----------------------------------+---------+
| 3013fa8f600145108b836228236cb8f3 | demo |
| 4a930be69d0540d38d5529449d93f1d0 | service |
| a7d90c2bbe1b49a18a04482447a52aa9 | admin |

为demo tenant  创建 port 如果在 admin tenant 在 demo tenant 下是无法看到的

source admin-openrc.sh 
[root@controller01 ~]# neutron port-create --tenant-id 3013fa8f600145108b836228236cb8f3 --fixed-ip subnet_id=27539347-f509-4368-9ec1-36dcb07942da,ip_address=172.16.0.123 flat

显示 port 列表

[root@controller01 ~]# neutron port-list
+--------------------------------------+------+-------------------+---------------------------------------------------------------------------------------+
| id | name | mac_address | fixed_ips |

attach port 到虚拟机
