Additional changes to remove privilaged command execution during the
installation proces. Also removed surplus file copies that are no longer
required.
A corner case where a vagrant VM isn't created before the installer is
run results in the vagrant-libvirt network not being defined or started.
Without this network the installer VM could not be started.
