If you are suggesting > they use the ec2 api then the uuids may not be needed. > I just misread: instead of d), I've read something like e) modify horizon to list ec2 images id together with glance uuid I will try to better explain the issue: I want my users to be able to customize some of the images already present on our cloud by creating snapshots. Then, they should be able to use our software (which uses EC2 api) to run their jobs. Our software is non-interactive, so I can't print a list from which the user can chose the correct image, the user must write the id on a configuration file. I thing d) or e) would be fine, but d) will make our use case hard to apply to other clouds, while if OpenStack would accept a patch for e) we could be able to use other clouds as well... .a. -- [email protected] GC3: Grid Computing Competence Center http://www.gc3.uzh.ch/ University of Zurich Winterthurerstrasse 190 CH-8057 Zurich Switzerland
