Getting a list of block storage volumes at Rackspace using novaclient Python API

I'm trying to get a list of the block storage volumes that I have on my Rackspace account using the novaclient Python API. Here's the code that I'm using:

from rackspace_auth_openstack.plugin import RackspaceAuthPlugin from rackspace_auth_openstack.plugin import auth_url_us

from novaclient.client import Client nova = Client(version = 2,
              username = '******',
              project_id = '******',
              api_key = '******************************',
              region_name = 'DFW',
              auth_system = 'rackspace',
              auth_plugin = RackspaceAuthPlugin(),
              auth_url = auth_url_us())

print nova.servers.list() print nova.volumes.list()

All of the libraries were installed using pip install --upgrade rackspace-novaclient so I should be using the lastest version of the libraries. Here's the results of running the above code:

$ python test.py 
[<Server: svr01>, <Server: svr02>]
Traceback (most recent call last):
  File "test.py", line 16, in <module>
    print nova.volumes.list()
  File "/usr/lib/python2.7/site-packages/novaclient/v1_1/volumes.py", line 95, in list
    return self._list("/volumes/detail%s" % query_string, "volumes")
  File "/usr/lib/python2.7/site-packages/novaclient/base.py", line 64, in _list
    _resp, body = self.api.client.get(url)
  File "/usr/lib/python2.7/site-packages/novaclient/client.py", line 283, in get
    return self._cs_request(url, 'GET', **kwargs)
  File "/usr/lib/python2.7/site-packages/novaclient/client.py", line 260, in _cs_request
    **kwargs)
  File "/usr/lib/python2.7/site-packages/novaclient/client.py", line 242, in _time_request
    resp, body = self.request(url, method, **kwargs)
  File "/usr/lib/python2.7/site-packages/novaclient/client.py", line 236, in request
    raise exceptions.from_response(resp, body, url, method)
novaclient.exceptions.NotFound: Not found (HTTP 404)

The server list API call works, so I'm pretty sure that I'm authenticating properly. The CLI command nova volume-list works properly so it would appear that I'm missing something from my code.

Since the Cloud Block Storage API is under a different endpoint, you have to specify the service_type

from rackspace_auth_openstack.plugin import RackspaceAuthPlugin, auth_url_us

from novaclient.client import Client
nova = Client(version = 2,
              username = '******',
              project_id = '******',
              api_key = '******************************',
              region_name = 'DFW',
              auth_system = 'rackspace',
              auth_plugin = RackspaceAuthPlugin(),
              auth_url = auth_url_us(),
              service_type = 'volume') # Right here

print nova.volumes.list()
