module: xenserver_guest_powerstate
short_description: Manages power states of virtual machines running on Citrix Hypervisor/XenServer host or pool
description: >
This module can be used to power on, power off, restart or suspend virtual machine and gracefully reboot or shutdown guest OS of virtual machine.
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:
U(https://raw.githubusercontent.com/xapi-project/xen-api/master/scripts/examples/python/XenAPI/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.'
requirements:
- python >= 2.6
- XenAPI
options:
state:
description:
- Specify the state VM should be in.
- If C(state) is set to value other than C(present), then VM is transitioned into required state and facts are returned.
- If C(state) is set to C(present), then VM is just checked for existence and facts are returned.
type: str
default: present
choices: [ powered-on, powered-off, restarted, shutdown-guest, reboot-guest, suspended, present ]
name:
description:
- Name of the VM to manage.
- 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 manage if known. This is XenServer's unique identifier.
- It is required if name is not unique.
type: str
wait_for_ip_address:
description:
- Wait until XenServer detects an IP address for the VM.
- This requires XenServer Tools to be preinstalled on the VM to work properly.
type: bool
default: no
state_change_timeout:
description:
- 'By default, module will wait indefinitely for VM to change state or acquire an IP address if C(wait_for_ip_address: yes).'
- If this parameter is set to positive value, the module will instead wait specified number of seconds for the state change.
- In case of timeout, module will generate an error message.
type: int
default: 0
