1、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:rootlinux-node1 # ip add list 1: lo: 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
2、 :1/128 scope host valid_lft forever preferred_lft forever 2: eth0: 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 li
3、nk valid_lft forever preferred_lft forever 4: virbr0: 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: mtu 1500 qdisc pfifo_fast master v
4、irbr0 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： rootlinux-node1 # virsh net-list Name State Autostart Persistent - default active yes yes使用“virsh net-destroy default”删除 rootlinux-node1 # virsh net-destroy default Network default destroyed 从配置文件中剔除 rootlinux-node
5、1 # virsh net-undefine default Network default has been undefined 重启 libvirtd 服务 rootlinux-node1 # systemctl restart libvirtd.service rootlinux-node1 # virsh net-list Name State Autostart Persistent - rootlinux-node1 # ip add list 1: lo: mtu 65536 qdisc noqueue state UNKNOWN qlen 1 link/loopback 00:
6、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: 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
