Hey,
thanks that solves this issue.
Most documentation I find is marked as "deprecated", the storage
documenation does not clearly reflect this.
Anway,
thanks for clearing this issue!
See here for the "sort of confirmation" of deprecation of ISO domains, not stated anywhere else:
and here for a bug when using block based storage domains (FC and iSCSI), opened in 4.2 and always postponed to be solved (now targeted for 4.3.9 for solution):
