This wishlist bug has been open a year without any activity. I'm going
to move it to "Opinion / Wishlist", which is an easily-obtainable queue
of older requests that have come on.

In case you want to work on that, consider writing a blueprints [1] and
spec [2]. I'll recommend to read [3] if not yet done. The effort to
implement the requested feature is then driven only by the blueprint
(and spec).

Title:
  HyperV driver does not implement Image cache ageing

Status in OpenStack Compute (nova):
  Opinion

Bug description:
  Nova.conf has the following options for image cache ageing
  remove_unused_base_images
  remove_unused_original_minimum_age_seconds.

  If these conf values are enabled, older un-used images cached on the hypervisor hosts will be deleted by nova-compute.
  The driver should implement the defn manage_image_cache
  and this will be called by compute.manager._run_image_cache_manager_pass().

  The HyperV driver does not implement manage_image_cache() which means
  older unused images (VHD/VHDFx) will never get deleted and occupy
  storage on the HyperV host, which otherwise can be used to spawn
  instances.
