The vmware_vm_vm_drs_rule module

With this module, you can configure VMware DRS Affinity rules. These allow you to control the placement of virtual machines within your cluster:

- name: Create DRS Affinity Rule for VM-VM  vmware_vm_vm_drs_rule:    hostname: "{{ vsphere_host }}"    username: "{{ vsphere_username }}"    password: "{{ vsphere_password }}"    cluster_name: "cluster"    vms: "{{ item }}"    drs_rule_name: ""    enabled: "True"    mandatory: "True"    affinity_rule: "True"  with_items:    - "example_vm"    - "another_example_vm"

In the previous example, we are creating a rule that will result in the VMs example_vm and another_example_vm never running on the same physical host.
