Added configuration option ``[api]/local_metadata_per_cell`` to allow
|
|
users to run Nova metadata API service per cell. Doing this could provide
|
|
performance improvement and data isolation in a multi-cell deployment.
|
|
But it has some caveats, see the
|
|
`Metadata api service in cells v2 layout`_ for more details.
