The sandbox build needs to validate two axis - A variety of distro versions - A variety of libvirt versions We test a variety of libvirt versions by running a build against the distro provided libvirt packages. All that is then missing is a build against the latest libvirt git master, which only needs to be run on a single distro, for which CentOS 7 is picked as a stable long life base.
