RHEV-M/oVirt templates as glance images
© Copyright 2013 Hewlett-Packard Development Company, L.P.
In the current OpenStack architecture, to deploy an instance from an image, the images have to be available in glance. Images are added using the glance image-create command. This command uploads the images into the glance server.
RHEV-M/oVirt already has the deployable images in the form of “Templates”. This blueprint proposes to make
1. Glance aware of the RHEV-M/oVirt templates
2. Avoid upload of RHEV-M/oVirt templates into the image server
The advantages are:
1. RHEV-M/oVirt Driver can be used to deploy the images to the RHEV hosts. The driver will use the oVirt Rest API to deploy the template. It leverages RHEV-M/oVirt template deployment optimizations.
2. Avoids the copy of the RHEV-M/oVirt images into the glance image server
This can be achieved by uploading the RHEV-M/oVirt template reference as OVF file(less than 5 KB) into the glance backend store. This avoids the copy of complete RHEV-M/oVirt template into the glance backend store.

This still looks possible in havana, but not in havana-2. We should discuss the status of this blueprint soon at a glance team meeting.
