[重庆思庄每日技术分享]-如何卸载rhel7以上版本的虚拟网桥virbr0

rhel7 以图形界面安装就会给你装个xbox，然后就会搞出来个虚拟网桥virbr0

本来就是装在VMware里的，不可能在里面又搞一个虚拟环境。

virbr0的存在还拖慢了系统，搞复杂了网络，还不如鸡肋呢。

如下:

[root@o11gserver ~]# ip a

1: lo: mtu 65536 qdisc noqueue state UNKNOWN

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: ens33: mtu 1500 qdisc pfifo_fast state UP qlen 1000

link/ether 00:0c:29:4d:37:a3 brd ff:ff:ff:ff:ff:ff

inet 192.168.0.115/24 brd 192.168.0.255 scope global dynamic ens33

valid_lft 7196sec preferred_lft 7196sec

inet6 fe80::2d5a:531f:8664:f55c/64 scope link

valid_lft forever preferred_lft forever

3: virbr0: mtu 1500 qdisc noqueue state DOWN

link/ether 52:54:00:6d:89:31 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

4: virbr0-nic: mtu 1500 qdisc pfifo_fast master virbr0 state DOWN qlen 500

link/ether 52:54:00:6d:89:31 brd ff:ff:ff:ff:ff:ff

[root@o11gserver ~]# brctl show

bridge name     bridge id               STP enabled     interfaces

virbr0          8000.5254006d8931       yes             virbr0-nic

试了网上的一些方法,结果都不靠普,最后,发现,只有卸载这个网桥,具体方法为:

yum remove libvirt-libs.x86_64 ,

并重启服务器,之后,就再也不见烦人的virbr0了.

[root@dbserver ~]# ip a

1: lo: mtu 65536 qdisc noqueue state UNKNOWN

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: ens33: mtu 1500 qdisc pfifo_fast state UP qlen 1000

link/ether 00:0c:29:29:02:46 brd ff:ff:ff:ff:ff:ff

inet 192.168.0.152/24 brd 192.168.0.255 scope global dynamic ens33

valid_lft 6088sec preferred_lft 6088sec

inet6 fe80::12fe:801b:35a2:bd5/64 scope link

valid_lft forever preferred_lft forever

inet6 fe80::2d5a:531f:8664:f55c/64 scope link tentative dadfailed

valid_lft forever preferred_lft forever

以上在rhel 7.4上测试通过.
