Re: About python versions that we are planning to support
[In reply to]
Python 2.4 compatibility is required, but only for agent code. Agent code needs to be deployable on Xen dom0, which uses CentoOS 5.5 and only supports 2.4 out of the box.
Both quantum and nova have agent code that needs to be deployed to dom0, but up until now both projects have relied on savvy reviewers and bug reports to ensure compatibility. I'm working on it, though. I'll be adding a tox build to quantum that will run agent tests - and agent tests only - under 2.4, and then openstack-ci can add a jenkins job to run that build on CentOS and gate merges.
The relevant bug: https://bugs.launchpad.net/quantum/+bug/995278
