1，物理机配置,eth0,eth1 配置bonding，bonding 作为bridge 物理网卡，在生成bond0 作为物理机管理口
2，虚拟机配置，eth1 作为bridge 虚拟网卡br500, eth0 配置正常网卡IP
3, 因eth0 为WEB 段， eth1 为DB 段，需颠倒配置，重启网卡，出现以下问题
4，相关错误日志：

解决办法： 1，在重启网卡之前，需要删除老的bridge 配置 ifconfig br500 down brctl delbr br500 ifdown eth1 systemctl stop network.service systemctl start network.service 2, 直接重启云主机
