My sample vagrant file for three hosts with our -nocm boxes May have to update it for Vagrant 1.1/1.2, http://docs.vagrantup.com/v2

Vagrantfile

Vagrant::Config.run do |config|
  #config.vm.box = "base"
  config.vm.define :master do |master_config|
    master_config.vm.box = "ubuntu-12.04.2-server-amd64-vbox-428-nocm.box"
    master_config.vm.box_url = "http://puppet-vagrant-boxes.puppetlabs.com/ubuntu-server-12042-x64-vbox4210-nocm.box"
    master_config.vm.forward_port 443,8443
    master_config.vm.forward_port 22,20022
    master_config.vm.network :hostonly, "172.16.253.5"
    master_config.vm.share_folder("modules", "/modules", "./modules")
