服務(wù)器維護CentOS 7下刪除virbr0網(wǎng)卡信息

服務(wù)器維護小知識說明：之前在CentOS7下配置過bridge，現(xiàn)在講bridge模式改為普通模式后，查看網(wǎng)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(wǎng)卡配置信息，操作如下:
服務(wù)器維護小知識 [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
服務(wù)器維護小知識查看網(wǎng)絡(luò)列表：
[root@linux-node1 ~]# virsh net-list
 Name                State      Autostart    Persistent
----------------------------------------------------------
 default              active    yes          yes
服務(wù)器維護小知識使用“virsh net-destroy default”刪除
[root@linux-node1 ~]# virsh net-destroy default
Network default destroyed
服務(wù)器維護小知識從配置文件中剔除
[root@linux-node1 ~]# virsh net-undefine default
Network default has been undefined
服務(wù)器維護小知識重啟libvirtd服務(wù)
[root@linux-node1 ~]# systemctl restart libvirtd.service
[root@linux-node1 ~]# virsh net-list
