  <p>my Vagrantfile is descripted  below, it uses shell scripts for installation and spinning puppet server machine and 2 nodes using virtualbox as VM and debian wheezy as Guest OS.Provisioning machine is giving some erratic error hard to debug, kindly resolve the issue. FYI, all files, nodes.json, boostrap-master.sh, bootstrap-node.sh,site.pp are lying along side of "Vagrantfile"</p>
