==========================================================
Servers - run an administrative action (servers, action)
==========================================================
Enables administrators to perform an action on a server. Specify the
action in the request body.
You can inject network information into, migrate, live-migrate,
reset networking on, and reset the state of a server.
Inject Network Information (injectNetworkInfo Action)
=====================================================
.. rest_method:: POST /servers/{server_id}/action
Injects network information into a server.
Specify the ``injectNetworkInfo`` action in the request body.
Policy defaults enable only users with the administrative role to
perform this operation. Cloud providers can change these permissions
through the ``policy.json`` file.
.. warning:: There is very limited support on this API, For more information,
see `nova virt support matrix
<https://docs.openstack.org/nova/latest/user/support-matrix.html>`__
Normal response codes: 202
Error response codes: unauthorized(401), forbidden(403), itemNotFound(404), conflict(409)
Request
-------
.. rest_parameters:: parameters.yaml
- server_id: server_id_path
- injectNetworkInfo: injectNetworkInfo
**Example Inject Network Information (injectNetworkInfo Action)**
.. literalinclude:: ../../doc/api_samples/os-admin-actions/admin-actions-inject-network-info.json
:language: javascript
Response
--------
If successful, this method does not return content in the response body.
Migrate Server (migrate Action)
===============================
.. rest_method:: POST /servers/{server_id}/action
Migrates a server to a host. The scheduler chooses the host.
Specify the ``migrate`` action in the request body.
Policy defaults enable only users with the administrative role to
perform this operation. Cloud providers can change these permissions
through the ``policy.json`` file.
Normal response codes: 202
Error response codes: badRequest(400), unauthorized(401), forbidden(403)
itemNotFound(404), conflict(409)
Request
-------
.. rest_parameters:: parameters.yaml
- server_id: server_id_path
- migrate: migrate
**Example Migrate Server (migrate Action)**
.. literalinclude:: ../../doc/api_samples/os-migrate-server/migrate-server.json
:language: javascript
Response
--------
If successful, this method does not return content in the response body.
Live-Migrate Server (os-migrateLive Action)
===========================================
.. rest_method:: POST /servers/{server_id}/action
Live-migrates a server to a new host without rebooting.
Specify the ``os-migrateLive`` action in the request body.
Use the ``host`` parameter to specify the destination host. If
this param is ``null``, the scheduler chooses a host. If a scheduled host
is not suitable to do migration, the scheduler tries up to
``migrate_max_retries`` rescheduling attempts.
Starting from API version 2.25, the ``block_migration`` parameter could be
to ``auto`` so that nova can decide value of block_migration during live
migration.
Policy defaults enable only users with the administrative role to
perform this operation. Cloud providers can change these permissions
through the ``policy.json`` file.
Starting from REST API version 2.34 pre-live-migration checks are done
asynchronously, results of these checks are available in ``instance-actions``.
Nova responds immediately, and no pre-live-migration checks are returned.
The instance will not immediately change state to ``ERROR``, if a failure of
the live-migration checks occurs.
Normal response codes: 202
Error response codes: badRequest(400), unauthorized(401), forbidden(403)
itemNotFound(404), conflict(409)

- os-migrateLive: os-migrateLive
- host: host_migration
- block_migration: block_migration

If successful, this method does not return content in the response body.
Reset Networking On A Server (resetNetwork Action)
==================================================
.. rest_method:: POST /servers/{server_id}/action
Resets networking on a server.
.. note::
Only the XenServer driver implements this feature and only if the guest
has the XenAPI agent in the targeted server.
Specify the ``resetNetwork`` action in the request body.
Policy defaults enable only users with the administrative role to
perform this operation. Cloud providers can change these permissions
through the ``policy.json`` file.
