GlanceSupportForXS

Release Note

By implementing support for XenServer to pull out images from Glance will enable users to use Swift, or any other object stores supported by Glance, for storing their images to be used by compute nodes.

Rationale

Glance provides an image registration and discovery service (Parallax) and an image delivery service (Teller). These services are used in conjunction by Nova to deliver images from object stores, such as Swift service, to Nova’s compute nodes.

Currently, XenServer for OpenStack fetches images from the OpenStack local object store. This implementation will enable XenServer to use Glance services to fetch images registered in Swift, or other object stores supported by Glance.

Assumptions

Glance integration with Nova in Bexar

Design

You can have subsections that better describe specific parts of the issue.

Implementation

This section should describe a plan of action (the "how") to implement the changes discussed. Could include subsections like:

UI Changes

Should cover changes required to the UI, or specific UI that is required to implement this

Code Changes

Code changes should include an overview of what needs to change, and in some cases even the specific details.

Migration

Include:

• data migration, if any
• redirects from old URLs to new ones, if any
• how users will be pointed to the new way of doing things, if necessary.

Test/Demo Plan

This need not be added or completed until the specification is nearing beta.

Unresolved issues

This should highlight any issues that should be addressed in further specifications, and not problems with the specification itself; since any specification with problems cannot be approved.

BoF agenda and discussion

Use this section to take notes during the BoF; if you keep it in the approved spec, use it for summarising what was discussed and note any options that were rejected.
