openstack 3.14.3 虚拟机增加指定IP网卡

1、查看 openstack版本信息，以下命令是在 queen版本下执行没有问题。

1 2	`[root@node151 ~]# openstack --version` `openstack 3.14.3`

2、查看网络接口信息

[root@node151 ~]# neutron port-list
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.

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

3、查看网络信息

[root@node151 ~]# neutron net-list
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
+--------------------------------------+----------+----------------------------------+-----------------------------------------------------+
| id                                   | name     | tenant_id                        | subnets                                             |
+--------------------------------------+----------+----------------------------------+-----------------------------------------------------+
| b79db6a0-b74d-48b8-95e8-8260eaf81b70 | provider | 8e4dd46886834371b71984245a143f58 | b8a9d01c-f547-45c3-a0d4-da7ae1494766 192.168.1.0/24 |
+--------------------------------------+----------+----------------------------------+-----------------------------------------------------+

4、创建网络接口指定ip地址、网络信息

1	`neutron port-create --fixed-ip subnet_id=<替换为上一步获取到的 subnets>,ip_address=<替换为指定的IP> <替换为上一步的网络ID>`

[root@node151 ~]# neutron port-create --fixed-ip subnet_id=b8a9d01c-f547-45c3-a0d4-da7ae1494766,ip_address=192.168.1.168 b79db6a0-b74d-48b8-95e8-8260eaf81b70
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
Created a new port:

5、将新增加的接口，绑定到对应的vm上

5.1 查看虚拟机信息

[root@node151 ~]# nova list
+--------------------------------------+---------------+---------+------------+-------------+------------------------+
| ID                                   | Name          | Status  | Task State | Power State | Networks               |
+--------------------------------------+---------------+---------+------------+-------------+------------------------+
| a02050c0-ed9a-4fb1-93e9-595a57bb654e | centos-1      | ACTIVE  | -          | Running     | provider=192.168.1.156 |
| de86908f-91fb-48a7-8b69-1d07d8c3aea0 | centos-2      | SHUTOFF | -          | NOSTATE     | provider=192.168.1.159 |
| 371fe316-7db5-4781-987f-e0b514d525bd | centos-3      | ACTIVE  | -          | Running     |                        |
+--------------------------------------+---------------+---------+------------+-------------+------------------------+

　5.2 绑定vm机

1	`nova` `interface-attach --port-id <替换为上一步的网络接口ID> <替换为上一步的虚拟机的ID>`

[root@node151 ~]# nova interface-attach --port-id cd86f69a-4779-4a46-a0ea-eed76f176237 371fe316-7db5-4781-987f-e0b514d525bd
[root@node151 ~]# nova list
+--------------------------------------+---------------+---------+------------+-------------+------------------------+
| ID                                   | Name          | Status  | Task State | Power State | Networks               |
+--------------------------------------+---------------+---------+------------+-------------+------------------------+
| a02050c0-ed9a-4fb1-93e9-595a57bb654e | centos-1      | ACTIVE  | -          | Running     | provider=192.168.1.156 |
| de86908f-91fb-48a7-8b69-1d07d8c3aea0 | centos-2      | SHUTOFF | -          | NOSTATE     | provider=192.168.1.159 |
| 371fe316-7db5-4781-987f-e0b514d525bd | centos-3      | ACTIVE  | -          | Running     | provider=192.168.1.168 |
| f3419061-97ca-4846-b667-0672ea2f8ca4 | centos6.9-tpl | SHUTOFF | -          | Shutdown    | provider=192.168.1.157 |
+--------------------------------------+---------------+---------+------------+-------------+------------------------+

6、重启查看虚拟机，网络接口已经绑定上

如果网卡信息显示不一致，通过console登录修改网卡名称，以centos6 为列

[root@t168 ~]# more /etc/udev/rules.d/70-persistent-net.rules 
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.
 
# PCI device 0x1af4:0x1000 (virtio-pci)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="fa:16:3e:b7:03:80", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
