This completes the DELETE method body verification for server migrations. This was only supported in microversion >= 2.24 and only on the libvirt driver so there are notes about it being conditional.

Force Migration Complete Action (force_complete Action)
|
|
=======================================================
|
|
|
|
.. rest_method:: POST /servers/{server_id}/migrations/{migration_id}/action
|
|
|
|
Force an in-progress live migration for a given server to complete.
|
|
|
|
Specify the ``force_complete`` action in the request body.
|
|
|
|
.. note:: Microversion 2.22 or greater is required for this API.
|
|
|
|
.. note:: Not all compute back ends support forcefully completing an
|
|
in-progress 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.
|
|
|
|
**Preconditions**
|
|
|
|
The server OS-EXT-STS:vm_state value must be ``active`` and the server
|
|
OS-EXT-STS:task_state value must be ``migrating``.
|
|
|
|
If the server is locked, you must have administrator privileges to force the
|
|
completion of the server migration.
|
|
|
|
The migration status must be ``running``.
|
|
|
|
**Asynchronous Postconditions**
|
|
|
|
After you make this request, you typically must keep polling the server status
|
|
to determine whether the request succeeded.
|
|
|
|
**Troubleshooting**
|
|
|
|
If the server status remains ``ACTIVE`` for an inordinate amount of time, the
|
|
request may have failed. Ensure you meet the preconditions and run the request
|
|
again. If the request fails again, investigate the compute back end.
|
|
|
|
Normal response codes: 202

Delete (Abort) Migration
|
|
========================
|
|
|
|
.. rest_method:: DELETE /servers/{server_id}/migrations/{migration_id}
|
|
|
|
Abort an in-progress live migration.
|
|
|
|
.. note:: Microversion 2.24 or greater is required for this API.
|
|
|
|
.. note:: Not all compute back ends support aborting an in-progress 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.
|
|
|
|
**Preconditions**
|
|
|
|
The server OS-EXT-STS:task_state value must be ``migrating``.

|
|
completion of the server migration.
|
|
|
|
The migration status must be ``running``.
|
|
|
|
**Asynchronous Postconditions**
|
|
|
|
After you make this request, you typically must keep polling the server status
|
|
to determine whether the request succeeded. You may also monitor the migration
|
|
using::
|
|
|
|
GET /servers/{server_id}/migrations/{migration_id}
|
|
|
|
**Troubleshooting**
|
|
|
|
If the server task_state remains ``migrating`` for an inordinate amount of
|
|
time, the request may have failed. Ensure you meet the preconditions and run
|
|
the request again. If the request fails again, investigate the compute back
|
|
end.
