You'll need someone more familiar with backend stuff. But it looks like your host is not installed correctly, or you have network issues.

If this is a fresh installation, I'd try just starting over. Reinstall your OSes, make sure they are yum updated, reboot them, and then:

1. setup engine according to https://www.ovirt.org/documentation/install-guide/chap-Installing_oVirt/ 
2. on your host, ONLY install ` yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm` on top of CentOS. That's all you need to do.
3. add the host via the UI.
