As far as install progress goes, the local hosted-engine comes up and runs on the node.

As a result, that DNS address will never resolve, and the IP it resolves to won't be up. I gave the installation script permission to modify the local /etc/hosts but this hasn't improved things. > > I presume I'm missing something in the install process, or earlier on in the logs, but I've been scanning for errors and possible clues to no avail. > > Any and all help greatly appreciated! Please check/share, on the engine machine under /var/log/ovirt-engine, or, if inaccessible, on the host, under /var/log/ovirt-hosted-engine-setup/engine-logs-*: engine.log host-deploy/* Good luck and best regards,
