The problem now is at final step where I get

On engine VM I see a reference to " CreateStorageDomainVDS failed: Invalid parameter: 'block_size=None'" in engine.log

BTW: in my second test with the workaround of pre-creation of directory I scratched all before and set the gluster network to 192.168.123.0 to avoid conflict with the temporary bridge. I didn't get anymore the json error described in item 3) of my first post
