Please try this, from the engine machine, as user root: ssh -i /etc/pki/ovirt-engine/keys/engine_id_rsa HOST Replace "HOST" with the name or address you input in the field "Address" in the "New Host" dialog. I think that's 'node1', from above. Does it work? If not, please check sshd configuration/logs on the host.
