Looking into this a big more `openstack overcloud image build` takes in the yaml config files you list and converts that into a forked diskimage-builder process to build an image. The centos7 dib element in particular seems to have aarch64 support via building on top of the upstream centos7 aarch64 image. We do use the centos-minimal element for our images though as it allows us to do things like install glean. Chances are we still need need to sort out UEFI and GPT for general dib use. Just to be sure there isn't any other magic going on can you provide the contents of the overcloud-aarch64.yaml or point to where it can be found? It doesn't appear to be in tripleo-common with the other configs. It is good to know that this is working in some cases though.
