ISO domains are deprecated. I guess you can upload to regular data domains.

I am now not clear on how to add the new ISO domain in. I created a new ISO domain type via storage and pointed to an NFS share on the new storage, however it does not behave as I anticipated (I cannot see ISO's when creating new VM's) I suspect I missed a step - how are new ISO domains added to a cluster?
