标题: 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: <LOOPBACK,UP,LOWER_UP> 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: <BROADCAST,MULTICAST,UP,LOWER_UP> 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: <NO-CARRIER,BROADCAST,MULTICAST,UP> 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: <BROADCAST,MULTICAST> 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

以上在rhel 7.4上测试通过.
