Open Stack

Heh, seems we're both running in the same direction.

If you're using Keystone with Nova, you also have to use Keystone with Glance (assuming you're using Glance).

Is this the case?

the patch suggested by Sandy works like a charm, it remains the question about
the strange comparison :-/


Now I have another problem,

using a python script like this:
NOVA_PROJECT_ID=1234
NOVA_USERNAME="joeuser"
NOVA_URL='http://192.168.0.100:5000/v2.0/'
NOVA_API_KEY='fdf50e55-8f02-4aac-ac02-0adcb088325d'
from novaclient.v1_1 import client
nt = client.Client(NOVA_USERNAME, 'secrete', NOVA_PROJECT_ID, NOVA_URL)


with this statement I obtain:

nt.images.list()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

File "/usr/lib/python2.6/site-packages/python_novaclient-2.6.4-py2.6.egg/novaclient/v1_1/images.py",

File "/usr/lib/python2.6/site-packages/python_novaclient-2.6.4-py2.6.egg/novaclient/base.py",

line 96, in request
    raise exceptions.from_response(resp, body)
novaclient.exceptions.BadRequest: n/a (HTTP 400

Any suggestions?
Carlo
