This Ruby example lists the ISO files in the ISO storage domain, myiso.

# Get the reference to the root of the services tree:
system_service = connection.system_service

# Find the service that manages the collection of storage domains:
sds_service = system_service.storage_domains_service

# Find the ISO storage domain:
sd = sds_service.list(search: 'name=myiso').first

# Find the service that manages the ISO storage domain:
sd_service = sds_service.storage_domain_service(sd.id)

# Find the service that manages the collection of files available in the storage domain:
files_service = sd_service.files_service

# List the names of the files. Note that the name of the .iso file is contained
# in the id attribute.
files = files_service.list
files.each do |file|
  puts file.id
end

If you do not know the name of the ISO storage domain, this Ruby example retrieves all the ISO storage domains.

# Find the ISO storage domain:
iso_sds = sds_service.list.select { |sd| sd.type == OvirtSDK4::StorageDomainType::ISO }
