As a side note, The current the v4.3 API docs shows that the only field of a disk that can be update is `qcow_version` ( http://ovirt.github.io/ovirt-engine-api-model/4.3/#services/disk/methods/update). While all the properties, including the inner disk properties, are supported when updating a disk-attachment ( http://ovirt.github.io/ovirt-engine-api-model/4.3/#services/disk_attachment/methods/update ).
So if I want to extend the disk size or some other changes, I need to use its disk-attachment representation. However, the v4.3 API does not support to fetch all the relevant disk-attachments by a disk id. In my view, maybe there should have a interconnection of the disk, disk-attachment and vm. Thanks.
