网络下载的代码，因我的是pike版本，与代码的版本有区别，运行出现诸多版本问题，经调试修改代码，测试通过，记录如下：
#!/usr/bin/python
from keystoneclient.auth.identity import v3
from keystoneclient import session
from keystoneclient.v3 import client as keystoneapi
from novaclient import client as novapi
auth_url = 'http://192.168.0.100/identity/v3'
username = 'admin'
user_domain_name = 'Default'
project_name = 'admin'
project_domain_name = 'Default'
password = '****'
auth = v3.Password(auth_url=auth_url,
username=username,
password=password,
project_name=project_name,
project_domain_name=project_domain_name,
user_domain_name=user_domain_name)
sess = session.Session(auth=auth)
keystone = keystoneapi.Client(session=sess)
#print keystone.projects.list() 列出所有项目
nova = novapi.Client(2, session=keystone.session)
#print nova.glance.list() 列出所有镜像
image = nova.glance.find_image('cirros-0.3.5-x86_64-disk')
#print nova.flavors.list() 列出所有主机类型
flavor = nova.flavors.find(name='m1.tiny')
#print nova.neutron.list() 列出所有网络,有问题，后来通过直接查数据库解决
network = nova.neutron.find_network('vxlan100')
#创建虚拟机
server = nova.servers.create(name="vm_api", image=image, flavor=flavor,nics=[{'net-id':network.id}])
print server创建的实例正常运行
