May i know what was the volume type created and added as ISO domain ?

If you plan to use a glusterfs volume below is the procedure :

1) Create a glusterfs volume.
2) While adding storage domain select Domain Function as 'ISO' and 
Storage Type as 'glusterfs' .
3) You can either use 'use managed gluster volume' check box and select 
the gluster volume which you have created for storing ISO's or you can 
type the full path of the volume.
4) Once this is added please make sure to set the option nfs.disable off.
5) Now you can go to HE engine and run the command engine-iso-uploader 
upload -i <gluster_iso_domain_name> <iso_file>

Iso gets uploaded successfully.

AFAIK, this is not required when glusterfs volume is used.

Attached is the screenshot where i have only one network attached to my 
HE which is ovirtmgmt.
