<p class="MsoNormal"><span lang="EN-US">we are a public cloud provider based on OpenStack and many of our customers and partners unfortunately still request CentOS 7 images for their VMs. In my team we support the upstream development of OpenStack SDK and OpenStack
Client (both seem to be de facto one combined team now) and also provide some extensions specific to our cloud (via a plugin mechanism in recent releases of the SDK).<u></u><u></u></span></p>
<p class="MsoNormal"><span lang="EN-US"><u></u> <u></u></span></p>
<p class="MsoNormal"><span lang="EN-US">Our clients frequently ask for updated RPMs for CentOS 7. I wonder if you as CentOS community at large are interested in having them as well, or, if not, if you could point me in the right direction how to build them.<u></u><u></u></span></p>
<p class="MsoNormal"><span lang="EN-US"><u></u> <u></u></span></p>
<p class="MsoNormal"><span lang="EN-US">One major conflict I am currently struggling with is that virtually all Python 2.7 code is not only no longer supported (due to a community goal in OpenStack), but actually removed (which is in itself a good decision,
no doubt about it). The mentioned packages work well with Python 3, but as I understand it, Python 3 is not available by vanilla CentOS 7.<u></u><u></u></span></p>
