^^^^^^

Bug Fixes

* A new "[workarounds]/reserve_disk_resource_for_image_cache" config
  option was added to fix the bug 1878024 where the images in the
  compute image cache overallocate the local disk. If this new config
  is set then the libvirt driver will reserve DISK_GB resources in
  placement based on the actual disk usage of the image cache.
