module: xenserver_guest_info
short_description: Gathers information for virtual machines running on Citrix Hypervisor/XenServer host or pool
description: >
   This module can be used to gather essential VM facts.
version_added: '2.8'
author:
- Bojan Vitnik (@bvitnik) <bvitnik@mainstream.rs>
notes:
- Minimal supported version of XenServer is 5.6.
- Module was tested with XenServer 6.5, 7.1, 7.2, 7.6, Citrix Hypervisor 8.0, XCP-ng 7.6 and 8.0.
- 'To acquire XenAPI Python library, just run C(pip install XenAPI) on your Ansible Control Node. The library can also be found inside
   Citrix Hypervisor/XenServer SDK (downloadable from Citrix website). Copy the XenAPI.py file from the SDK to your Python site-packages on your
   Ansible Control Node to use it. Latest version of the library can also be acquired from GitHub:
   https://raw.githubusercontent.com/xapi-project/xen-api/master/scripts/examples/python/XenAPI.py'
- 'If no scheme is specified in C(hostname), module defaults to C(http://) because C(https://) is problematic in most setups. Make sure you are
   accessing XenServer host in trusted environment or use C(https://) scheme explicitly.'
- 'To use C(https://) scheme for C(hostname) you have to either import host certificate to your OS certificate store or use C(validate_certs: no)
   which requires XenAPI library from XenServer 7.2 SDK or newer and Python 2.7.9 or newer.'
- This module was called C(xenserver_guest_facts) before Ansible 2.9. The usage did not change.
requirements:
- python >= 2.6
- XenAPI
options:
  name:
    description:
    - Name of the VM to gather facts from.
    - VMs running on XenServer do not necessarily have unique names. The module will fail if multiple VMs with same name are found.
    - In case of multiple VMs with same name, use C(uuid) to uniquely specify VM to manage.
    - This parameter is case sensitive.
    type: str
    required: yes
    aliases: [ name_label ]
  uuid:
    description:
    - UUID of the VM to gather fact of. This is XenServer's unique identifier.
    - It is required if name is not unique.
