Hi Jain,
Thanks for the quick answer.
>export OS_PASSWORD="your-password"
Do you mean the password according to the value of
"env.openstack_admin_password =" entry in testbed.py ?
Because I ran this same sequence, setting OS_PASSWORD to
the value of "env.openstack_admin_password" entry in testbed.py, and
it did not work, I got the same error:

nova list
No handlers could be found for logger
"keystoneclient.auth.identity.generic.base"
  ERROR (ServiceUnavailable): Service Unavailable (HTTP 503)

Does it work for you ? Do you work with a contrail 3.* release ?
