创建网络
提供者为external，类型为flat，网络名称为public，:
root@controller:~# neutron net-create --shared --provider:physical_network external --provider:network_type flat public
Created a new network:

创建子网
子网名称：public-subnet
子网范围：192.168.10.10,192.168.10.100
root@controller:~# neutron subnet-create --name public-subnet --allocation-pool start=192.168.10.10,end=192.168.10.100 --dns-nameserver 114.114.114.114 --gateway 192.168.10.1 public 192.168.10.0/24
Created a new subnet:

子网创建好后，network节点会创建一个虚拟网桥：
root@network:~# brctl show
bridge name bridge id STP enabled interfaces
brq75c074be-19 8000.000c29db9568 no eth1
tapb11ba192-6d
创建虚拟机
先要新建一把key:
root@controller:~# nova keypair-add mykey
root@controller:~# nova keypair-list
+-------+-------------------------------------------------+
| Name | Fingerprint |
+-------+-------------------------------------------------+
| mykey | 45:c1:71:78:e5:8c:c4:08:d1:af:a3:69:e6:66:96:c5 |
+-------+-------------------------------------------------+
启动虚拟机：
root@controller:~# nova boot --flavor m1.tiny --image cirros-0.3.3-x86_64 --nic net-id=75c074be-1905-495d-9c2a-413761e0f67b --security-group default --key-name mykey demo1
获取虚拟机vnc：
root@controller:~# nova get-vnc-console demo1 novnc
