Thanks Eric, As you'll see from the intro email to this thread, the purpose here is to ensure that we don't strand a 'non-trivial' number of users by dropping support for any given hypervisor, or management server operating system.
Hence the request to users to let the community know what they are using, so that a fact-based community consensus can be reached.

It is running antique versions of everything, and has been doing so for quite some time. It is, for example, running versions of Gnome and init that have been obsolete for years. Same deal with the version of MySQL that it comes with. The reality is that Centos 6.x guest support, at the very least, needs to be tested with each new version of Cloudstack until final EOL of Centos 6 in Q2 2020. New versions of Cloudstack with new features not supported by Centos 6 (such as LVM support for KVM, which requires the LIO storage stack) can require Centos 7 or later, but the last Cloudstack version that supports Centos 6.x as its server host should continue to receive bug fixes until Centos 6.x is EOL. Making someone's IT investment obsolete is a way to irrelevancy. Cloudstack is already an also-ran in the cloud marketplace. Making someone's IT investment obsolete before the official EOL time for their IT investment is a good way to have a mass migration away from your technology. This doesn't particularly affect me since my Centos 6 virtualization hosts are not running Cloudstack and are going to be re-imaged to Centos 7 before being added to the Cloudstack cluster, but ignoring the IT environment that people actually live in, as versus the one we wish existed, is annoying regardless. A friend of mine once said of the state of ERP software, "enterprise software is dog food if dog food was being designed by cats." I.e., the people writing the software rarely have any understanding of how it is actually used by real life enterprises in real life environments. Don't be those people.
