This is probably a configuration bug or a general lack of understanding, but I can't seem to find the problem.  I've installed the latest Essex release (on instances running in Diablo) to verify my upgrade tasks.  However, I'm unable to get Glance to download images (which prevents running instances).  I'm able to upload images into the backend Swift store. I can perform image listings, etc, however when I try to download an image, I receive a 404 error, file not found.

To verify, I've run the following curl commands directly on the glance api service.  To wit:

1. First, obtain a token

curl -d '{"auth": {"tenantName": "admin", "passwordCredentials": {"username": "admin", "password": "admin"}}}' -H "Content-type: application/json" http://essex1:35357/v2.0/tokens | python -mjson.tool

and I receive the output (edited)

      }
        ], 
        "token": {
            "expires": "2012-04-27T15:30:45Z", 
            "id": "45d01460a0e04bff967eb954e7f4fee8", 
            "tenant": {
                "description": "All administrative tasks are to be grouped underneath this tenancy.  Users are not to be associated with this tenant unless they have been granted admin roles.", 
                "enabled": true, 
                "id": "1", 
                "name": "admin"
            }
        }, 

2. Next, do a listing as follows:

root at essex1:/etc/keystone# curl -v -H 'X-Auth-Token: 45d01460a0e04bff967eb954e7f4fee8' -H 'Content-type: application/json' http://essex3:9292/v1/images | python -mjson.tool

    ]
}

3. I can even do a HEAD on a particular image.  For example:

root at essex1:/etc/keystone# curl -v -I -H 'X-Auth-Token: 45d01460a0e04bff967eb954e7f4fee8' -H 'Content-type: application/json' http://essex3:9292/v1/images/6720c572-12b7-4cc8-a8c5-95b92998671a | python -mjson.tool

4.  However, when I try to download the same image, I receive the following error:

I first noticed this when trying to instantiate and instance, and it was failing when trying to download the kernel image specified by the kernel_id property of the associated ami image.

Any clues?  My glance-api.conf file is appended at the end of this message.  Thanks for any insights that can be provided.

Regards,
Ross
