Downloaded "ovirt-node-ng-installer-ovirt-4.2-2018051606.iso" from
http://jenkins.ovirt.org/job/ovirt-node-ng_ovirt-4.2_build-artifacts-el7-...
After rebooting any node, even though they all have valid IP addresses,
I can not connect (via SSH) to any node unless I "systemctl restart
network.service"
Maybe I'm using the wrong iso?
