MANAGE right requirement on image for disk snapshot unjustified with ceph
|Category:||Core & System|
|Target version:||Release 5.6|
|Affected Versions:||OpenNebula 5.2|
With opennebula 5.2, snapshoting a disk requires the MANAGE permissions on the original image. While it might be required for some storage driver, it's not with ceph. Since the volume used by the VM is a rbd clone of the original image, the rbd snapshot only requires read permissions on the original image (which is implicit since the volume the user is trying to snapshot has already be cloned from the image, the user already has read permissions on the original image).
