Openstack的删除错误网桥，虚拟网络
在实验openstack的各种网络模式时，可能会产生一些错误的网络指向，需要删除那些网桥。执行前
# ifconfig
br40 Link encap:EthernetHWaddr FA:16:3E:F3:68:A4
inet addr:172.17.39.4Bcast:172.17.39.255Mask:255.255.255.0
inet6 addr: fe80::dcfb:8bff:fe62:5171/64 Scope:Link
UP BROADCAST RUNNING MULTICASTMTU:1500Metric:1

TX packets:34 errors:0 dropped:0 overruns:0 carrier:0

vlan40 Link encap:EthernetHWaddr FA:16:3E:F3:68:A4
inet6 addr: fe80::f816:3eff:fef3:68a4/64 Scope:Link
UP BROADCAST RUNNING MULTICASTMTU:1500Metric:1

TX packets:40 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 b)TX bytes:4977 (4.8 KiB)
执行命令
# vconfig rem vlan40
Removed VLAN -:vlan40:-
# ifconfig br40 down
# brctl delbr br40
在次执行ifconfig,将看到不在存在这2个虚拟网络和网桥了
