說明：之前在CentOS7下配置過bridge，現在講bridge模式改為普通模式后，查看網卡的時候還是可以看到很多垃圾信息，想徹底刪除自己不想要的網卡配置信息，操作如下:

[root@linux-node1 ~]# ip add list1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00    inet 127.0.0.1/8 scope host lo       valid_lft forever preferred_lft forever    inet6 ::1/128 scope host        valid_lft forever preferred_lft forever2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000    link/ether 00:0c:29:9b:7d:d6 brd ff:ff:ff:ff:ff:ff    inet 10.10.10.11/24 brd 10.10.10.255 scope global eth0       valid_lft forever preferred_lft forever    inet6 fe80::20c:29ff:fe9b:7dd6/64 scope link        valid_lft forever preferred_lft forever4: virbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN qlen 1000    link/ether 52:54:00:f4:24:05 brd ff:ff:ff:ff:ff:ff    inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0       valid_lft forever preferred_lft forever5: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast master virbr0 state DOWN qlen 1000    link/ether 52:54:00:f4:24:05 brd ff:ff:ff:ff:ff:ff

查看網絡列表：

[root@linux-node1 ~]# virsh net-list Name                 State      Autostart     Persistent---------------------------------------------------------- default              active     yes           yes

使用“virsh net-destroy default”刪除

[root@linux-node1 ~]# virsh net-destroy defaultNetwork default destroyed

從配置文件中剔除

[root@linux-node1 ~]# virsh net-undefine defaultNetwork default has been undefined

重啟libvirtd服務

[root@linux-node1 ~]# systemctl restart libvirtd.service[root@linux-node1 ~]# virsh net-list Name                 State      Autostart     Persistent----------------------------------------------------------[root@linux-node1 ~]# ip add list1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00    inet 127.0.0.1/8 scope host lo       valid_lft forever preferred_lft forever    inet6 ::1/128 scope host        valid_lft forever preferred_lft forever2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000    link/ether 00:0c:29:9b:7d:d6 brd ff:ff:ff:ff:ff:ff    inet 10.10.10.11/24 brd 10.10.10.255 scope global eth0       valid_lft forever preferred_lft forever    inet6 fe80::20c:29ff:fe9b:7dd6/64 scope link        valid_lft forever preferred_lft forever

再次查看，發現不必要的信息已經清除，清爽多了
