Since ovirt 4.2 it is acceptable to have ISO images in storage domains of DATA type, while the usage of ISO type is about to be deprecated. https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/html/release_notes/deprecated_features_rhv https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.4-beta/html/release_notes/deprecated_features_rhv Currently, the StorageDomain type in libgovirt only has support for the 'files' query, and this is only available for objects with ISO type, while the correct query for objecs of type DATA is 'disks'. It is necessary to provide new API in libgovirt making it the support for 'disks' query availabe for storage domain objects.
