module: vmware_guest_powerstate
short_description: Manages power states of virtual machines in vCenter
description:
- Power on / Power off / Restart a virtual machine.
version_added: '2.5'
author:
- Abhijeet Kasurde (@akasurde) <akasurde@redhat.com>
requirements:
- python >= 2.6
- PyVmomi
options:
state:
description:
- Set the state of the virtual machine.
choices: [ powered-off, powered-on, reboot-guest, restarted, shutdown-guest, suspended ]
name:
description:
- Name of the virtual machine to work with.
- Virtual machine names in vCenter are not necessarily unique, which may be problematic, see C(name_match).
name_match:
description:
- If multiple virtual machines matching the name, use the first or last found.
default: first
choices: [ first, last ]
uuid:
description:
- UUID of the instance to manage if known, this is VMware's unique identifier.
- This is required if name is not supplied.
folder:
description:
- Destination folder, absolute or relative path to find an existing guest or create the new guest.
- The folder should include the datacenter. ESX's datacenter is ha-datacenter
- 'Examples:'
- ' folder: /ha-datacenter/vm'
- ' folder: ha-datacenter/vm'
- ' folder: /datacenter1/vm'
- ' folder: datacenter1/vm'
- ' folder: /datacenter1/vm/folder1'
- ' folder: datacenter1/vm/folder1'
- ' folder: /folder1/datacenter1/vm'
- ' folder: folder1/datacenter1/vm'
- ' folder: /folder1/datacenter1/vm/folder2'
- ' folder: vm/folder2'
- ' folder: folder2'
