Hi Ihar, Thanks very much for your quick response. I'm a little bit curious about why Juno do not support EL6, is this because CentOS6 is using python2.6 , and Juno is the release to support python 2.6? And it seems like if we want to upgrade from Icehouse/Havana to juno in production, we need to upgrade CentOS6 to CentOS7 ...

Thank Perry for your kindly help! It's very clear. Thanks.

Partly it is because the upstream OpenStack community is very eager to move off of Python 2.6. We had pressure even in Icehouse to move off of 2.6, but because CentOS7 wasn't released at that point, we had a bit of a buffer and released Icehouse on both CentOS6 and CentOS7 But now that CentOS7 is released, it makes sense to now get off of the old python stack so that the upstream community can focus on python 2.7 and beyond. In addition, we have limited resources for packaging, CI and testing. If we could get help from other community members to take on the burden of packaging for EL6, helping to test it and maintain CI jobs for it, we would not be opposed to that. But with the existing RDO packaging/CI team that we have, continuing to maintain BOTH EL6 and EL7 is just too much. And yes, if you wanted to go from RDO Icehouse on EL6 to RDO Juno, it would involve a transition from CentOS6 to CentOS7. When we considered what to do with RDO Icehouse, initially we thought of only doing RDO Icehouse on CentOS7 or CentOS6 but not both. In the end, we did Icehouse on 6 and 7 specifically to provide a release where there was overlap. But we only ever intended (and had staffing) to provide a single release on both platforms. I hope that answers some of your questions. Thanks for asking! Perry

We'll invest time to help bring people up to speed and work with them so they can be productive and help out in any area that they want to contribute in. The more the merrier :)

Thanks for the clarification on the plans. In view of installed base at CERN (now over 3,000 servers), we would be interested in el6 support for Juno and would like to discuss the details of how this could be done in Paris. The components of particular interest for us are Nova, Ceilometer and the client packages. Could you describe the work involved so we can review skills and availability on our side ? How about an RDO BOF at the summit ? Tim, Jan, et al.

I believe there is general space, as well though. Once the details of the design summit are more clear, it's just a matter of picking a time and agreeing to meet in this area. -- Russell Bryant

For us, we want to move to Juno+CentOS 7 for new installs. It is not clear to me that we can run for an extended period with some of the compute nodes on Icehouse and others on Juno. Theory indicates that this may be possible but it remains to be seen. Tim

We've experienced that need to support two branches requires a lot of energy that is better spent to make EL7 release more mature. Upstream still supports Juno for Python 2.6, but support will be dropped in Kilo (the next cycle). As for the upgrade path, yes, you'll need EL7 to be able to use RDO Juno. You will need to migrate to EL7 in the future anyway if you're planning to use pieces from Kilo. BTW the same approach is true for the next version of Red Hat commercial OpenStack distribution (RHEL-OSP6 based on Juno). I hope that helps, /Ihar
