说明：之前在CentOS7下配置过bridge，现在讲bridge模式改为普通模式后，查看网卡的时候还是可以看到很多垃圾信息，想彻底删除自己不想要的网卡配置信息，操作如下:
[root@linux-node1 ~]# ip add list
1: 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 forever
2: 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
4: 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 forever
5: 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
查看网络列表：
[root@linux-node1 ~]# virsh net-list
Name State Autostart Persistent
----------------------------------------------------------
default active yes yes
使用“virsh net-destroy default”删除
[root@linux-node1 ~]# virsh net-destroy default
Network default destroyed
从配置文件中剔除
[root@linux-node1 ~]# virsh net-undefine default
Network default has been undefined
重启libvirtd服务
[root@linux-node1 ~]# systemctl restart libvirtd.service
[root@linux-node1 ~]# virsh net-list
Name State Autostart Persistent
----------------------------------------------------------
[root@linux-node1 ~]# ip add list
1: 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 forever
2: 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，发现不必要的信息已经清除，清爽多了
