It is now possible to signal and perform an update of an instance's power
|
|
state as of the 2.76 microversion using the ``power-update`` external
|
|
event. Currently it is only supported in the ironic driver and through
|
|
this event Ironic will send all "power-on to power-off" and
|
|
"power-off to power-on" type power state changes on a physical instance
|
|
to nova which will update its database accordingly. This way nova will
|
|
not be able to enforce an incorrect power state on the physical instance
|
|
during the periodic ``_sync_power_states`` task. The changes to the power
|
|
state of an instance caused by this event can be viewed through
|
|
``GET /servers/{server_id}/os-instance-actions`` and
|
|
``GET /servers/{server_id}/os-instance-actions/{request_id}``.

Until all the ``nova-compute`` services that run the ironic driver are
|
|
upgraded to the Train code that handles the ``power-update`` callbacks from
|
|
ironic, the ``[nova]/send_power_notifications`` config option can be kept
|
|
disabled in ironic.
