在计算节点上，如下命令

ovs-vsctl list-br


值为空 没有br-int 和br-tun

这里面存在两个问题，
1.Nova配置有问题
2.ovs有问题
楼主需细心检测，先确保服务都是正常的

我觉得是ovs的问题 卸载了重装后 也不好使

ExecStart=/usr/bin/neutron-openvswitch-agent --config-file /usrfile:///C:\Users\ZHANG-PC\AppData\Local\Temp\UG9`
楼主则是啥
去看看日志

/usrfile:///C:\Users\ZHANG-PC\AppData\Local\Temp\UG9`这个是考入Windows时出错了 ，去掉这些看。

===================
从日志看你的 /etc/neutron/neutron.conf 权限不对被拒绝了。
正常的权限是：
[root@compute01 ~]# ll /etc/neutron/neutron.conf
-rw-r----- 1 root neutron 36437 May 18 12:12 /etc/neutron/neutron.conf
[root@compute01 ~]#
