Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "trusty64"
  config.vm.provision :shell, path: "../bootstrap.sh"

  config.vm.network "public_network", bridge: "br-1", ip: "192.168.56.1"

  config.vm.provider :virtualbox do |vb|
  #   # Don't boot with headless mode
  #   vb.gui = true
  #
  #   # Use VBoxManage to customize the VM. For example to change memory:
      vb.customize ["modifyvm", :id, "--memory", "1024"]
      vb.customize ["modifyvm", :id, "--cpuexecutioncap", "50"]
      vb.customize ["modifyvm", :id, "--ioapic", "on"]
      vb.customize ["modifyvm", :id, "--cpus", "4"]
  end
end

where i can find the bootstrap.sh file that you have used in the above vagrant file.
