Problema para rodar o puppet automaticamente

Boa tarde, seguindo o exercício da aula '5. Rodando o puppet automaticamente' utilizando o Vagrantfile a seguir:

Vagrant.configure(2) do |config|
    config.vm.box = "hashicorp/precise32"

    config.vm.define :web do |web_config|
        web_config.vm.network "private_network", ip: "192.168.50.10"
        web_config.vm.provision "puppet" do |puppet|
            puppet.manifest_file = "web.pp"
        end
    end
end

A saída foi diferente da mostrada no vídeo, dizendo que a maquina virtual já havia sido provisionada. Conforme o log:

    web: your host and reload your VM.

Para que o puppet rode tenho que usar o comando a seguir indicado pelo vagrant vagrant provision, acredito que o comportamento da ferramenta tenha mudado. Alguém sabe dizer se realmente se trata de uma mudança de comportamento ou se algo mais é necessário para que se tenha o comportamento desejado de o puppet rodar juntamente com vagrant up?
