Durante a instalação foi criado o usuário vagrant com a senha vagrant e foi usado a senha para o usuário root.

Instalação miníma. Apenas o SSH foi marcado para ser instalado.

Com foi feita uma instalação miníma, vamos instalar o sudo e o python. O python é opcional. Nesse caso será instalado caso seja necessário o provisionamento com o ansible. Já o sudo é obrigatório já que precisamos usar o usuário vagrant com privilégios de root quando formos usar a box.
