2.8. Migrating the ISO Domain from 3.6
Migrate the ISO domain from 3.6 to the current version of Red Hat Virtualization, using the iso_domain.tar.gz backup file that you created during the upgrade from 3.6 to 4.0.
The new directory for the ISO domain must not be on the Manager machine.
The ISO domain is deprecated in Red Hat Virtualization 4.2, and will be removed in a future version. Red Hat recommends uploading ISO images to a data storage domain. See Uploading Images to a Data Storage Domain in the Administration Guide.
Create an export directory on the storage server and set its permissions:
mkdir -p /var/lib/exports/iso chown -R 36:36 /var/lib/exports/
