原因：

配置linuxbridge agent的时候没有替换网卡信息

分析过程

打开DEBUG级别日志发现缺少linux bridge agent

打开 openstackDEBUG级别日志_yue_luu的博客-优快云博客

2022-08-14 10:50:39.975 50636 DEBUG neutron.plugins.ml2.drivers.mech_agent [req-9c3ec1e1-53a5-495f-8b79-448d50c3275e - - - - -] Port 3a144298-c39f-4722-8c95-e66ddac308a6 on network 45c89664-9173-4117-b095-e9e8468c36b8 not bound, no agent of type Linux bridge agent registered on host controller bind_port /usr/lib/python2.7/site-packages/neutron/plugins/ml2/drivers/mech_agent.py:104

openstack network agent list查不到linux bridge agent

[root@controller ~]# openstack network  agent list

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

systemctl status却显示正常

linuxbridge agent日志显示启动失败

2022-08-14 11:19:02.361 77840 ERROR neutron.plugins.ml2.drivers.linuxbridge.agent.linuxbridge_neutron_agent [-] Interface PROVIDER_INTERFACE_NAME for physical network provider does not exist. Agent terminated!

原来是/etc/neutron/plugins/ml2/linuxbridge_agent.ini 配置的时候没有替换物理网卡信息

还有其他配置文件没有修改的也一起改一下

修改完就正常啦
