Images in Glance can be in one the following statuses:
queued
The image identifier has been reserved for an image in the Glance registry. No image data has been uploaded to Glance.
saving
Denotes that an image’s raw data is currently being uploaded to Glance. When an image is registered with a call to POST /images and there is an x-image-meta-location header present, that image will never be in the saving status (as the image data is already available in some other location).
active
Denotes an image that is fully available in Glance.
killed
Denotes that an error occurred during the uploading of an image’s data, and that the image is not readable.
deleted
Glance has retained the information about the image, but it is no longer available to use. An image in this state will be removed automatically at a later date.
pending_delete
This is similiar to deleted, however, Glance has not yet removed the image data. An image in this state is recoverable.
