(waiting for my Centos 7 container to install Development Tools - the
default Centos container I got previously was v6 and it doesn't have
Qt >= 4.7...)

So, because Linus said "Don't break userspace", pretty much any old
Linux distro will work fine in a container on any modern kernel. I
regularly run all sorts of old distros in containers on a modernish
host (Debian Stretch, in my case).

In fact, containers work better, in many cases, than full
virtualisation, because the old device drivers are not always able
to drive the emulated devices provided in recent VMs so well.
