简介 Centos7下删除virbr0网卡信息的方法_RedHat/Centos_操作系统_

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:  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:  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:  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 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:  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:  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
