Unfortunately shortly after the oVirt 4.1.7 release we discovered a critical issue with ovirt-node-ng. The issue was promptly handled, and fixed packages were pushed into the repo. Also the ovirt-node-ng-installer ISO was rebuilt. Please make sure to update your repo and use the fixed ovirt-node-ng-installer ISO: http://plain.resources.ovirt.org/pub/ovirt-4.1/iso/ovirt-node-ng-installer-o... -- Lev Veyde Software Engineer, RHCE | RHCVA | MCITP Red Hat Israel <https://www.redhat.com> lev@redhat.com | lveyde@redhat.com <https://red.ht/sig> TRIED.
