Example Playbook

Example of calling the same role multiple times without loop role:

- name: install a libvirt and openstack VM
  hosts: localhost
  roles:
  - role: vm
    vm_type: libvirt
    vm_host: virthost
    vm_cpu_cores: 4
    vm_memory: 4096
  - role: vm
    vm_type: openstack
    vm_memory: 4096
    vm_image: cirros

Example of calling the same role multiple times with loop role:

- name: install a libvirt and openstack VM
  hosts: localhost
  roles:
  - role: loop
    loop_role: vm
    loop_items:
    - type: libvirt
      host: virthost
      cpu_cores: 4
      memory: 4096
    - type: openstack
      memory: 4096
      image: cirros

Same thing except passing list of items as a variable:

- name: install a libvirt and openstack VM
  hosts: localhost
  vars:
    vm_list:
    - type: libvirt
      host: virthost
      cpu_cores: 4
      memory: 4096
    - type: openstack
      memory: 4096
      image: cirros
  roles:
  - role: loop
    loop_role: vm
    loop_items: "{{ vm_list }}"
