libvirt-coreos is a cluster provider for kubernetes that starts local VMs and
runs kubernetes on it.
Its goal is to provide a multi-machines environment to develop and test kubernetes.

The purpose is mostly the same as the vagrant provider but with a big focus on
efficiency. The vagrant cluster takes a long time to boot and consumes a huge
amount of disk space. libvirt-coreos aims at being cheaper. As a consequence,
libvirt-coreos allows to start bigger clusters with more minions than vagrant.
