There is also openstack built by the oldest version of centos at home, vm has always been an error

I checked ifconfig 10.0.0.11 is normal. brqxxx occupies 10.0.0.11 address!

But the ifconfig of 10.0.0.31 is abnormal. brqxxx does not occupy 10.0.0.31 address!

Baidu check: openstack ifconfig brq no ip

Know some query commands

I probably checked the openstack component configuration file.

I think it is necessary to check why the ifconfig of 10.0.0.31 is abnormal. brqxxx does not occupy 10.0.0.31 address! Is it a problem with libvirtd.service, or

One more network bridge brqxxxxx, and the previous configuration of the IP address of the physical network card enoxxxx is assigned to the network bridge. View bridge information through brctl:

$ brctl show brqxxxx view information and 10.0.0.11 are correct, there are obvious differences! ! ! Caused
