Summary
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.
User stories
XenServer users could take advantage of Glance to register and manager their images.
Assumptions
Glance integration with Nova in Bexar
Design
You can have subsections that better describe specific parts of the issue.
Implementation
Rework virt.xenapi
UI Changes
There should be no visible changes to the end users.
Code Changes
Code changes should be isolated to xenapi component in the virt module.
Migration
Migration once when the implementation nears beta.
The only change for users is that they could register their images to Swift when Glance is integrated with Nova.
Test/Demo Plan
Unit tests will be provided as code is developed.
Unresolved issues
None.
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.
