.. caution::
Deleting an image does not affect instances or snapshots that were
based on the image.
Generally, deleting an image does not affect instances or snapshots that were
based on the image. However, some drivers may require the original image to be
present to perform a migration. For example, XenAPI live-migrate will work
fine if the image is deleted, but libvirt will fail.
