All,
As of about a week ago, we've been able to build Vagrant boxes containing the CentOS Atomic build in the CBS. I've put up an example script in my development fork of the Atomic SIG repo here:
https://github.com/imcleod/sig-atomic-buildscripts/tree/devel-cbs-script
The "do_vagrant_cbs.sh" script in particular will flatten the atomic/vagrant kickstart files and kick off a scratch build. This assumes you have access to the CBS and have set up a koji profile called "cbs" pointing at the CentOS infra. Details here:
http://wiki.centos.org/HowTos/CommunityBuildSystem
Here's a successful scratch build:
https://cbs.centos.org/koji/taskinfo?taskID=7820
Note that the output is, for the moment, confusingly named.
The Vagrant Virtualbox ".box" file (most commonly used on Mac) has the extension ".vsphere.ova"
The Vagrant KVM/libvirt ".box file has the extension ".rhevm.ova"
