Why is my playbook not calling up the roles?

Question

I have an ansible playbook which I call from my Vagrantfile:

config.vm.provision "ansible" do |ansible|
     ansible.playbook = "provision/playbook.yml"
     ansible.sudo = true
     ansible.verbose = "vvvv"
     ansible.limit = "all"
     # ansible.inventory_path = "provision/hosts"
end

This is the playbook:

---
- hosts: all
  roles:
    - common

My directory structure is:

.
├── provision
│   ├── hosts
│   ├── playbook.yml
│   └── roles
│       └── common
│           ├── install_conda.yml
│           └── reqs.yml
├── ubuntu-xenial-16.04-cloudimg-console.log
└── Vagrantfile

My problem is when I run vagrant up it does not run the install_conda.yml and reqs.yml

What am I missing here ?

Ansible looks for a main.yml file in your roles/common/tasks.

Just add it to your folder

.
├── provision
│   ├── hosts
│   ├── playbook.yml
│   └── roles
│       └── common
│           └── tasks        
│               ├── main.yml
│               ├── install_conda.yml
│               └── reqs.yml
├── ubuntu-xenial-16.04-cloudimg-console.log
└── Vagrantfile    

and include the other roles:

---

- include: install_conda.yml
- include: reqs.yml
