module: vmware_host_feature_info
short_description: Gathers info about an ESXi host's feature capability information
description:
- This module can be used to gather information about an ESXi host's feature capability information when ESXi hostname or Cluster name is given.
version_added: '2.9'
author:
- Abhijeet Kasurde (@Akasurde)
notes:
- Tested on vSphere 6.5
requirements:
- python >= 2.6
- PyVmomi
options:
  cluster_name:
    description:
    - Name of the cluster from all host systems to be used for information gathering.
    - If C(esxi_hostname) is not given, this parameter is required.

  esxi_hostname:
    description:
    - ESXi hostname to gather information from.
    - If C(cluster_name) is not given, this parameter is required.
