[Bug 996233] Re: nova and python-novaclient disagree on volumes API URLs

Thu May 31 21:48:27 UTC 2012

Looking at William's trace, I see some differences with the traces I
get. Not posting a full one in the first place was foolish of me.  Here
it is now.

$ nova --debug volume-list

    raise exceptions.from_response(resp, body)
NotFound: n/a (HTTP 404)
ERROR: n/a (HTTP 404)

Whereas in William's trace the token is obtained with "POST
/v2.0/tokens" and the list operation is performed with "GET
/v1/5c9e830827e0412b92da25b128f5c63d/volumes/detail".

In the credentials packets we distribute to our Openstack users, we have
a file containing environment variables, which includes:

export NOVA_URL="http://XXX.XXX.XXX.XXX:8774/v1.1/"
export NOVA_VERSION="1.1"

However, when I set things up as follows:

export NOVA_URL="http://XXX.XXX.XXX.XXX:8774/v2.0/"
export NOVA_VERSION="2"

I get:

$ nova --debug volume-list
connect: (XXX.XXX.XXX.XXX, 8774)

Which seems to leave us with

=== the v1.1 issue ===

When using the v1.1 API, novaclient is not able to query Openstack for a
list of volumes. Is this supposed to be supported?

=== the v2 issue ===

The Openstack installation I'm testing against doesn't like the v2 API.
In nova-api.log I find:

2012-05-31 21:26:01 INFO nova.api.openstack.wsgi [-] POST http://XXX.XXX.XXX.XXX:8774/v2.0/tokens

2012-05-31 21:26:01 INFO nova.api.openstack.wsgi [-] http://XXX.XXX.XXX.XXX:8774/v2.0/tokens returned with HTTP 400

I'll look into this, but if someone recognizes the symptom or has any
ideas, that would be very helpful.
