oepnstack python sdk

我在使用openstack python sdk v2版本，查找image 时提示'Client' object has no attribute 'images'

这是官方给出的代码，我运行时候报错：




* #/usr/bin/python
#coding:utf-8

import time
from credentials import get_nova_credentials_v2
from novaclient.client import Client

try:
    credentials = get_nova_credentials_v2()
    nova_client = Client(**credentials)

    image = nova_client.images.find(name="cirros")
    print image
    print(nova_client.servers.list())
    flavor = nova_client.flavors.find(name="m1.tiny")
    print flavor
#    net = nova_client.networks.find(label="private")
#    print net
#    nics = [{'net-id': net.id}]
#    instance = nova_client.servers.create(name="vm2", image=image, flavor=flavor, key_name="keypair-1", nics=nics)
#    print("Sleeping for 5s after create command")
#    time.sleep(5)
#    print("List of VMs")
#    print(nova_client.servers.list())
finally:
    print("Execution Completed")

这是错误提示：


$ python create_instance.py 
admin
/usr/local/lib/python2.7/dist-packages/novaclient/client.py:264: UserWarning: The 'tenant_name' argument is deprecated in Ocata and its use may result in errors in future releases. Use 'project_name' instead.
