#bootstrap script for VM OPNFV nodes
#author: Tim Rozet (trozet@redhat.com)

#Uses Vagrant and VirtualBox
#VagrantFile uses vm_nodes_provision.sh which configures linux on nodes
#Depends on Foreman being up to be able to register and apply puppet
#
#Pre-requisties:
#Target system should be Centos7 Vagrant VM
