家裏還有最老一版本centos搭建的openstack，vm一直是error

我查了10.0.0.11的 ifconfig是正常的。brqxxx佔用10.0.0.11地址！

可是10.0.0.31的 ifconfig是不正常的。brqxxx沒佔用10.0.0.31地址！

百度查：openstack ifconfig brq無ip

知道一些查詢命令

由於openstack組件配置文件我大概查過了。

我以爲如今就要查爲何10.0.0.31的 ifconfig是不正常的。brqxxx沒佔用10.0.0.31地址！是否是libvirtd.service 問題，或者是

多出一個網橋brqxxxxx，而且以前物理網卡enoxxxx的IP地址等配置分配給了網橋。經過brctl 查看網橋信息：

$ brctl show brqxxxx查看信息和10.0.0.11正確的有明顯差別！！！形成的
