i can't see hosts after reinstall ovirt-appliance how to real hosts report to ovirt that "i'm online " ? a demon responsible for this?
When an oVirt Node is booted it tries to contact the oVirt Server by looking up its IP address via DNS SRV record. If it finds an oVirt Server it attempts to register with it.
However, if you reinstalled the ovirt-appliance and are using Nodes from a previous appliance installation this is not going to work since the Node will have a keytab from the old appliance. This is only a problem if you installed the Node onto a local hard disk. If you run the nodes completely stateless they always retrieve a new keytab on every boot.
