在宿主机里删除一个虚拟机关联的网卡、端口及桥
1）、用ovs-vsctl命令查看宿主机的所有的桥信息
[[email protected] ~]#ovs-vsctl show
169dc0d6-0c44-42df-9bd5-5e1f380a8704
Bridge br-int
Port int-br-int
Interface int-br-int
Port phy-br-int
Interface phy-br-int
Port "em2"
Interface "em2"
Port br-int
Interface br-int
type: internal
Port "qvo2bb4fd90-f1"
tag: 1
Interface"qvo2bb4fd90-f1"
ovs_version: "1.11.0"
2）、删除br-int桥下的qvo2bb4fd90-f1端口
[[email protected] ~]#ovs-vsctl del-port br-int qvo2bb4fd90-f1
3）、再次查看桥信息刚才的那个端口已经删除
[[email protected] ~]#ovs-vsctl show
169dc0d6-0c44-42df-9bd5-5e1f380a8704
Bridge br-int
Port int-br-int
Interface int-br-int
Port phy-br-int
Interface phy-br-int
Port "em2"
Interface "em2"
Port br-int
Interface br-int
type: internal
ovs_version: "1.11.0"
3）、用ifconfig查看全局接口信息
[[email protected] ~]#ifconfig | grep HWaddr
br-int Link encap:Ethernet HWaddr 74:86:7A:D9:05:19
em1 Link encap:Ethernet HWaddr 74:86:7A:D9:05:18
em2 Link encap:Ethernet HWaddr 74:86:7A:D9:05:19
int-br-int Linkencap:Ethernet HWaddr 42:D4:65:7C:EE:5E
phy-br-int Linkencap:Ethernet HWaddrAE:70:7F:C8:4E:53
qbr2bb4fd90-f1Link encap:Ethernet HWaddrF2:6E:69:E9:7B:62
qvb2bb4fd90-f1Link encap:Ethernet HWaddrF2:6E:69:E9:7B:62
qvo2bb4fd90-f1Link encap:Ethernet HWaddr F2:12:9A:D9:85:58
tap2bb4fd90-f1Link encap:Ethernet HWaddrFE:16:3E:0F:72:20
virbr0 Link encap:Ethernet HWaddr 52:54:00:07:56:A2
4）、把虚拟机关联的4个端口qbr2bb4fd90-f1qvb2bb4fd90-f1 qvo2bb4fd90-f1 tap2bb4fd90-f1都down掉
[[email protected] ~]#ifconfig qbr2bb4fd90-f1 down
[[email protected] ~]#ifconfig qvb2bb4fd90-f1 down
[[email protected] ~]#ifconfig qvo2bb4fd90-f1 down
[[email protected] ~]#ifconfig tap2bb4fd90-f1 down
5）、再次在全局下查看端口信息
[[email protected] ~]#ifconfig | grep HWaddr
br-int Link encap:Ethernet HWaddr 74:86:7A:D9:05:19
em1 Link encap:Ethernet HWaddr 74:86:7A:D9:05:18
em2 Link encap:Ethernet HWaddr 74:86:7A:D9:05:19
int-br-int Linkencap:Ethernet HWaddr42:D4:65:7C:EE:5E
phy-br-int Linkencap:Ethernet HWaddrAE:70:7F:C8:4E:53
virbr0 Link encap:Ethernet HWaddr 52:54:00:07:56:A2
6）、用brctl命令查看所有的桥信息
[[email protected]~]# brctl show
bridge name bridge id STP enabled interfaces
qbr2bb4fd90-f1 8000.f26e69e97b62 no qvb2bb4fd90-f1
tap2bb4fd90-f1
virbr0 8000.5254000756a2 yes virbr0-nic
[[email protected] ~]#
7)、删除虚拟机的桥qbr2bb4fd90-f1
[[email protected] ~]#brctl delbr qbr2bb4fd90-f1
[[email protected]~]# brctl show
bridge name bridge id STP enabled interfaces
virbr0 8000.5254000756a2 yes virbr0-nic
[[email protected] ~]#
8)、如果可以的话重启下服务器网卡
[[email protected] ~]#service network restart
