##### SUMMARY

The following snippet from https://github.com/ansible/ansible/blob/devel/test/integration/targets/vmware_guest/tasks/create_d1_c1_f0.yml uses `autoselect_datastore: True`.

```yaml
- name: create new VMs
  vmware_guest:
    validate_certs: False
    hostname: "{{ vcenter_hostname }}"
    username: "{{ vcenter_username }}"
    password: "{{ vcenter_password }}"
    name: newvm_1
    #template: "{{ item|basename }}"
    guest_id: centos64Guest
    datacenter: "{{ dc1 }}"
    hardware:
        num_cpus: 1
        num_cpu_cores_per_socket: 1
        memory_mb: 256
        hotadd_memory: true
        hotadd_cpu: false
        max_connections: 10
    disk:
        - size: 1gb
          type: thin
          autoselect_datastore: True
    state: poweredoff
    folder: F0
```

One of my two datastores is dedicated to the ISO image and so, is readOnly. But it still get selected consistently. I use the following hack to avoid the problem:
