We could re-do the project as a Multi-configuration project allowing you to run one build on the different builders as you wish.

That means on the other hand that we will need to delete the existing project and re-create one (ie: loosing your current set-up and history)

we want to run build job on different nodes(fedora, epel6 and epel7) at the same time when project has a new commit. Sounds good to me if we can achieve that by Multi-configuration project.
It's ok to delete current libabigail project from Jenkins@infra.

Thanks

Maybe do a back-up of your current set-up to make it easier to redeploy in the new project?

Thanks! Have already taken backup of current set-up. It should be ok to delete it.

Ok, I re-created the project https://jenkins.fedorainfracloud.org/job/libabigail/ and installed the dependencies on the EL6 and 7 builders.

Let us know if you need anything else :)
