IMO it should have passed this point. Use the answer file in
/etc/ovirt-hosted-engine,
not in /var . If all goes well they should be identical, otherwise
/etc will have the
"last known good" one and /var will have all.

But it might fail later during host-deploy. That stage requires ssh
from the engine
to the host as root (currently, there's an open RFE about this). But it does not
require a password, because we add the engine's public key to the host's
/root/.ssh/authorized_keys. So if you allow ssh as root with public key auth, it
should work.

Please check/post setup logs to try and understand why it was
identified as 1st host.

Not difficult in principle, currently not supported. As Sandro said, you can
open an RFE.

Best,
