XenServer has released os-xenapi lib on pypi, this patch is to use os-xenapi in nova project. In this patch, we only change the usage of XenAPI to os-xenapi and fix unit tests. In the next patch, we will delete those unused files.

destroy_cached_images.py
|
|
|
|
This script is used to clean up Glance images that are cached in the SR. By
|
|
default, this script will only cleanup unused cached images.
|
|
|
|
Options:
|
|
|
|
--dry_run - Don't actually destroy the VDIs
|
|
--all_cached - Destroy all cached images instead of just unused cached
|
|
images.
