liberty装好之后，做一个neutron的关于router的试验
建立router
neutron net-list
neutron subnet-list
neutron net-create private
ip netns
#这之后建立命名空间
neutron subnet-create --name private-subnet1 private 192.168.10.0/29
nova boot --image cirros --flavor 1 One
nova boot --image cirros --flavor 1 Two
nova boot --image cirros --flavor 1 Three
nova boot --image cirros --flavor 1 Four
neutron subnet-create --name private-subnet2 private 192.168.20.0/29
nova boot --image cirros --flavor 1 Five
nova list
ip netns exec qdhcp-c8c64093-fbde-4660-9f06-1bf7016b2a50 ip a
nova get-vnc-console Five novnc
neutron router-create --distributed=false MyRouter
#这也建立一个新的命名空间
