Yeah, the Docker version available in CentOS 6 EPEL is fairly old
and I doubt it's getting a lot of updates these days.

That said, we would be using it exclusively with images we've
crafted ourselves starting from official (and thus arguably
trustworthy) base images, and only to run build jobs locally, so
I'm not sure there's much to be concerned about security-wise.

Sure, that would probably do the trick as far as libvirt.org itself
is concerned; however, we would not only have to keep CentOS 6
around in the CentOS CI environment, but also figure out a way to
reproduce the same hack there if we want to make sure changes in
libvirt don't accidentally break building the website.

That doesn't sound too attractive overall, and more specifically
I'm not sure it would be much better than running an unsupported
Docker version.
