This module can be used to manage power states of host systems in given vCenter infrastructure. - User can set power state to 'power-down-to-standby', 'power-up-from-standby', 'shutdown-host' and 'reboot-host'. - State 'reboot-host', 'shutdown-host' and 'power-down-to-standby' are not supported by all the host systems. version_added: 2.6 author: - Abhijeet Kasurde (@Akasurde) requirements: - python >= 2.6 - PyVmomi options: state: description: -
