# openstack 使用 openvswitch + vxlan
# openstack  pike linuxbridge-agent 换为 openvswitch-agent

#控制节点

##########################
#安装过linuxbridge,需删除

#关闭,卸载linuxbridge-agent
systemctl disable neutron-linuxbridge-agent
systemctl stop    neutron-linuxbridge-agent
yum remove -y openstack-neutron-linuxbridge

#删除网络,在Web版操作
#释放虚拟ip地址——删除route——删除网络

# ##部分命令参考
# #查看bridge agent
# Bridge=`openstack network agent list | grep 'Linux bridge agent'|awk '{print $2}'`
# echo $Bridge
# #删除bridge agent
# neutron agent-delete $Bridge
# #删除网络
# NET=`openstack network list|awk '{print $2}'`
# echo $NET
# openstack network delete  $NET
