Bug Description

Using nova 78025e8 or later with the most recent glance commit ceab6b3 (image ids --> image refs).

I'm getting the following failures when trying to use the OSAPI to create an instance:

REQUEST: POST => /v1.1/admin/servers

In order to boot instances with the OSAPI I need just this change in image/glance.py:

Waldon. Looking at the S3 branch again now. I looked at that a week ago and didn't realize it encompassed the change needed for the OSAPI as well.

Okay. I pushed an isolated fix for the glance href issue here:

https://review.openstack.org/#change,1140

This resolves my issue booting instances w/ the OSAPI. My preference would be to fix that first and then look at the S3 issues separately.

Sounds like we have a bit of a standoff on this one. Removing myself as the assignee.

    Creating uuid -> id mapping for S3 Image Service

    This creates a mapping of Glance uuids to preserve the
    EC2-specific image id format. This adds a lazily generated
    mapping layer that is stored in the database.

    This also fixes bug 882658
