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, reset the state of a server,
|
|
and evacuate a server from a failed host to a new host.
|
|
|
|
|
|
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.
|
|

Migrate Server (migrate Action)
|
|
===============================
|
|
|
|
.. rest_method:: POST /servers/{server_id}/action
|
|
|
|
Migrates a server to a host.
|
|
|
|
Specify the ``migrate`` action in the request body.
|
|
|
|
Up to microversion 2.55, the scheduler chooses the host.
|
|
Starting from microversion 2.56, the ``host`` parameter is available
|
|
to specify the destination host. If you specify ``null`` or don't specify
|
|
this parameter, the scheduler chooses a host.
|
|
|
|
**Asynchronous Postconditions**
|
|
|
|
The server goes to a ``VERIFY_RESIZE`` status, ``RESIZED`` VM status,
|
|
and ``finished`` migration status after a successful cold migration
|
|
and then must be confirmed or reverted. If you set the
|
|
``resize_confirm_window`` option of the Compute service to a positive integer
|
|
value, the Compute service automatically confirms the migrate operation
|
|
after the set interval in seconds.
|
|
|
|
Policy defaults enable only users with the administrative role to
|
|
perform this operation. Cloud providers can change these permissions
|
|
through the ``policy.json`` file.

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.
|
|
|
|
Starting from API version 2.68, the ``force`` parameter is no longer accepted
|
|
as this could not be meaningfully supported by servers with complex resource
|
|
allocations.
