Is it possible to pack the following into a single role? My understanding that a role ONLY can be run on a defined set of hosts. 

- name: Provision a vagrant machine
      hosts: localhost
      vars:

```

```auto
        box: trusty64
      tasks:

```

```auto
        - name: create a Vagrantfile
          command: vagrant init {{ box }} creates=Vagrantfile

```

```auto
        - name: Bring up a vagrant server
          command: vagrant up

```

```auto
        - name: add the Vagrant hosts to the inventory
          add_host: >

```

```auto
                name=vagrant
                ansible_ssh_host=127.0.0.1
                ansible_ssh_port=2222
                ansible_ssh_user=vagrant
                ansible_ssh_private_key_file=/Users/lorinhochstein/.vagrant.d/
                insecure_private_key
 

```

```auto
    - name: Do something to the vagrant machine
      hosts: vagrant
      sudo: yes
      tasks:

```

You could use delegation to run some of the tasks on another machine  
(in this case localhost).

But to be honest I wouldn't, personally I'd split this into 2 plays.
