Just as a follow up on that issue (at the builder side) : as we saw that
we needed another builder/hypervisor for that kojid image builder
instance, I deployed today a centos 7.3.1611 node and added it to CBS :

It's not the first centos 7 builder (as we have already ppc64/ppc64le
and aarch64 centos 7 builders) but it was the first one on which we
tried the imagefactory image builder task.

Our first test wasn't working, but after some troubleshooting with
Laurentiu in #centos-devel (and analysis from python tracebacks) we
found the issue .
It seems there is a mismatch between koji version installed on the
builders and pykickstart from 7.3.1611 :


We'll investigate the koji upgrade later with Thomas, but the priority
was to build those Vagrant images, and so have a builder up and running.
The following "hot patch" seems to have solved the initial issues :

         ks = ksparser.KickstartParser(version)

After that, the tasks that were failing were able to run and produce
artifacts (vagrant boxes) :

Hope that it can unblock the situation and we'll discuss the potential
upgrade of the remaining builders to CentOS 7 too (and koji upgrade too,
after other tests)
