This release contains a fix for `bug 1748697`_ which distinguishes between
|
|
resize and cold migrate such that the ``allow_resize_to_same_host`` config
|
|
option is no longer used to determine if a server can be cold migrated to
|
|
the same compute service host. Now when requesting a cold migration the
|
|
API will check if the source compute node resource provider has the
|
|
``COMPUTE_SAME_HOST_COLD_MIGRATE`` trait and if so the scheduler can select
|
|
the source host. Note that the only in-tree compute driver that supports
|
|
cold migration to the same host is ``VMwareVCDriver``.
|
|
|
|
To support rolling upgrades with N-1 computes if a node does not report the
|
|
trait and is old the API will fallback to the ``allow_resize_to_same_host``
|
|
config option value. That compatibility will be removed in a subsequent
|
|
release.
