anchor.diff:      * **clusters** [Array, required]: Array of clusters to use for VM placement.
           * **&lt;cluster name&gt;** [String, required]: Cluster name.
               * **resource_pool** [String, optional]: Specific vSphere resource pool to use within the cluster.
  -
   * **nsx** [Dictionary, optional]: NSX configuration options.  This is required if the other NSX features are used below (e.g. 'security\_groups' for `resource\_pools`).
       * **address** [String, required]: The NSX server's address. Can be a hostname (e.g. `nsx-server.example.com`) or an IP address.
       * **user** [String, required]: The login username for the NSX server.
       * **password** [String, required]: The login password for the NSX server.
       * **ca_cert** [String, optional]: A CA certificate that can authenticate the NSX server certificate. **Required** if the NSX Manager has a self-signed SSL certificate. Must be in PEM format.
  -
  +* **enable_auto_anti_affinity_drs_rules** [Boolean, optional]: Creates DRS rule to place VMs on separate hosts. DRS Automation Level must be set to "Fully Automated"; does not work when DRS is set to "Partially Automated" or "Manual". May cause VMs to fail to power on if there are more VMs than hosts after initial deployment. Default: `false`. Available in v33+.
   <p class="note">Note: If the NSX Manager has a self-signed certificate, the certificate must be set in the `ca_cert` property.</p>
   
   Example of a CPI configuration that will place VMs into `BOSH_CL` cluster within `BOSH_DC`:
  
positive.code:       clusters: [BOSH_CL]
  ```
  
  Or example that places VMs by default into `BOSH_RP` vSphere resource pool with NSX integration:
  
  ```yaml
  properties:
  
negative.code:     user: root
      password: vmware
      default_disk_type: thin
      enable_auto_anti_affinity_drs_rules: true
      datacenters:
      - name: BOSH_DC
        vm_folder: prod-vms
