Cloud Host Configuration Docker Bridge, reverse configuration, restart NIC, cause physical NIC not working properly

1, physical machine configuration, eth0,eth1 configuration bonding,bonding as bridge physical network card, in the generation of bond0 as a physical machine management port

2, virtual machine configuration, eth1 as bridge virtual NIC br500, eth0 configure normal NIC IP

3, because Eth0 is a Web segment, eth1 DB segment, reverse configuration, restart the network card, the following problems occur

4, related error log:

Workaround: 1, before restarting the NIC, you need to remove the old bridge configuration ifconfig br500 down brctl delbr br500 ifdown eth1 Systemctl Stop Network.service systemctl start Network.service 2, restart the cloud host directly
