I am trying live migrate a server via the openstack python sdk.

from keystoneauth1.identity import v3
from keystoneauth1 import session
import json, ast

auth = v3.Password(auth_url='',
                   username='',
                   password='',
                   project_name='',
                   user_domain_id='',
                   project_domain_id='')

sess = session.Session(auth=auth)

print(sess)

from novaclient import client

nova = client.Client('2.30', session=sess)

servers = nova.servers.list()

for s in servers:
    print(s)
    # print(dir(s))
    s.live_migrate(host="oscnode1.localhost",block_migration=False,server=None)

Here is the error message I am getting

<Server: api_test_ubuntu2>
Traceback (most recent call last):
  File "C:/Users/a/PycharmProjects/openstack_api/openstack_sdk_v3.py", line 129, in <module>
    s.live_migrate(host="oscnode1.localhost",block_migration=False,server=None)
  File "C:\Python27\lib\site-packages\novaclient\api_versions.py", line 402, in substitution
    return methods[-1].func(obj, *args, **kwargs)
  File "C:\Python27\lib\site-packages\novaclient\v2\servers.py", line 1675, in live_migrate
    return self._action('os-migrateLive', server, body)
  File "C:\Python27\lib\site-packages\novaclient\base.py", line 180, in __getattr__
    raise AttributeError(k)
AttributeError: _action

I am able to connect and run other command to the nova api like nova.servers.list() and others.

I am using Python 2.7.12 on windows and python-openstackclient with python-novaclient both at the lastest versions.

Thanks for your help
