Image pre-caching on hosts by aggregate is now supported (where
|
|
supported by the underlying virt driver) as of microversion
|
|
2.81. A group of hosts within an aggregate can be compelled to
|
|
fetch and cache a list of images to reduce time-to-boot
|
|
latency. Adds the new API:
|
|
|
|
* ``POST /os-aggregates/{aggregate_id}/images``
|
|
|
|
which is controlled by the policy ``compute:aggregates:images`` rule.
|
|
|
|
See the `[image_cache]/precache_concurrency` config option
|
|
for more information about throttling this operation.
