Jabbar,
Could you please provide the information regarding "t2" in your code ?

[Ali Jabbar (jabbar-ali)]

Here is the code in t2.py

-------------------------------------
#!/usr/bin/env python
import os

def get_keystone_creds():
    d = {}
    d['username'] = os.environ['OS_USERNAME']
    d['password'] = os.environ['OS_PASSWORD']
    d['auth_url'] = os.environ['OS_AUTH_URL']
    d['tenant_name'] = os.environ['OS_TENANT_NAME']
    print d
    return d

def get_nova_creds():
    d = {}
    d['username'] = os.environ['OS_USERNAME']
    d['api_key'] = os.environ['OS_PASSWORD']
    d['auth_url'] = os.environ['OS_AUTH_URL']
    d['project_id'] = os.environ['OS_TENANT_NAME']
    print d
    return d
----------------------------
Just copy and try

I tried with same code, and got the same issue.

It seems all right on my environment, I ran this as follows:

[root@int32bit-centos ~(keystone_admin)]# cat test.py
import os
import time

from novaclient import client

def get_nova_creds():
    d = {}
    d['username'] = os.environ['OS_USERNAME']
    d['api_key'] = os.environ['OS_PASSWORD']
    d['auth_url'] = os.environ['OS_AUTH_URL']
    d['project_id'] = os.environ['OS_TENANT_NAME']
    print d
    return d

def main():
    creds = get_nova_creds()
    nova = client.Client(version=2,**creds)
    footest = nova.servers.get('d61af42c-d3b3-488a-98e2-2dc283b7c56b')
    print footest.interface_list()

if __name__ == '__main__':
    main()
[root@int32bit-centos ~(keystone_admin)]# python test.py
{'username': 'admin', 'project_id': 'admin', 'api_key': '8b9dada240e4476e', 'auth_url': 'http://192.168.0.4:5000/v2.0'}

It seems work fine.

Tested on my local devstack setup with novaclient version 6.0.0. It is working fine. Seems like the issue might be on your setup or the novaclient version you are using.
