6.4. 附加和分离虚拟网络接口

流程

1. 列出当前连接到裸机节点的 VIF ID：

   $ openstack baremetal node vif list baremetal-0
   +--------------------------------------+
   | ID                                   |
   +--------------------------------------+
   | 4475bc5a-6f6e-466d-bcb6-6c2dce0fba16 |
   +--------------------------------------+

2. 附加 VIF 后，裸机恢复调配服务使用物理端口的实际 MAC 地址更新 OpenStack 网络服务中的虚拟端口。检查此端口地址：

   $ openstack port show 4475bc5a-6f6e-466d-bcb6-6c2dce0fba16 -c mac_address -c fixed_ips
   +-------------+-----------------------------------------------------------------------------+
   | Field       | Value                                                                       |
   +-------------+-----------------------------------------------------------------------------+
   | fixed_ips   | ip_address='192.168.24.9', subnet_id='1d11c677-5946-4733-87c3-23a9e06077aa' |
   | mac_address | 00:2d:28:2f:8d:95                                                           |
   +-------------+-----------------------------------------------------------------------------+

3. 在您创建 baremetal-0 节点的网络中创建一个新端口：

   $ openstack port create --network baremetal --fixed-ip ip-address=192.168.24.24 baremetal-0-extra

   Copy to Clipboard Toggle word wrap

4. 从实例中删除端口：

   $ openstack server remove port overcloud-baremetal-0 4475bc5a-6f6e-466d-bcb6-6c2dce0fba16

   Copy to Clipboard Toggle word wrap

5. 检查列表中是否不再存在 IP 地址：

   $ openstack server list

   Copy to Clipboard Toggle word wrap

6. 检查是否有 VIFs 附加到节点：

   $ openstack baremetal node vif list baremetal-0
   $ openstack port list

   Copy to Clipboard Toggle word wrap

7. 添加新创建的端口：

   $ openstack server add port overcloud-baremetal-0 baremetal-0-extra

   Copy to Clipboard Toggle word wrap

8. 验证新 IP 地址是否显示新端口：

   $ openstack server list
   +--------------------------------------+-------------------------+--------+------------------------+----------------+---------+
   | ID                                   | Name                    | Status | Networks               | Image          | Flavor  |
   +--------------------------------------+-------------------------+--------+------------------------+----------------+---------+
   | 53095a64-1646-4dd1-bbf3-b51cbcc38789 | overcloud-controller-2  | ACTIVE | ctlplane=192.168.24.7  | overcloud-full | control |
   | 3a1bc89c-5d0d-44c7-a569-f2a3b4c73d65 | overcloud-controller-0  | ACTIVE | ctlplane=192.168.24.8  | overcloud-full | control |
   | 6b01531a-f55d-40e9-b3a2-6d02be0b915b | overcloud-controller-1  | ACTIVE | ctlplane=192.168.24.16 | overcloud-full | control |
   | c61cc52b-cc48-4903-a971-073c60f53091 | overcloud-novacompute-0overcloud-baremetal-0 | ACTIVE | ctlplane=192.168.24.24 | overcloud-full | compute |
   +--------------------------------------+-------------------------+--------+------------------------+----------------+---------+

9. 检查 VIF ID 是新端口的 UUID：

   $ openstack baremetal node vif list baremetal-0
   +--------------------------------------+
   | ID                                   |
   +--------------------------------------+
   | 6181c089-7e33-4f1c-b8fe-2523ff431ffc |
   +--------------------------------------+

   Copy to Clipboard Toggle word wrap

10. 检查 OpenStack 网络端口 MAC 地址是否已更新，并与裸机置备服务端口之一匹配：

    $ openstack port show 6181c089-7e33-4f1c-b8fe-2523ff431ffc -c mac_address -c fixed_ips
    +-------------+------------------------------------------------------------------------------+
    | Field       | Value                                                                        |
    +-------------+------------------------------------------------------------------------------+
    | fixed_ips   | ip_address='192.168.24.24', subnet_id='1d11c677-5946-4733-87c3-23a9e06077aa' |
    | mac_address | 00:2d:28:2f:8d:95                                                            |
    +-------------+------------------------------------------------------------------------------+

11. 重新引导裸机节点，以便它识别新的 IP 地址：

    $ openstack server reboot overcloud-baremetal-0

    Copy to Clipboard Toggle word wrap

    在分离或附加接口后，裸机操作系统会删除、添加或修改已更改的网络接口。当替换端口时，DHCP 请求会获取新的 IP 地址，但这可能需要一些时间，因为旧的 DHCP 租期仍然有效。要立即启动这些更改，请重新引导裸机主机。
