Thanks for clarifications.
It worked smoothly; all the three hosts are now up; going to test urther
functionalities.
Fine!

In the host-deploy logs for the 3 hosts I only see for the third host (and
for the first file of the two ones generated for first host) these kinds of
warning:


2016-11-16 11:09:48 DEBUG otopi.plugins.otopi.services.systemd

2016-11-16 11:09:49 WARNING otopi.plugins.ovirt_host_deploy.tune.tuned

Do I have to worry about them?

Thanks again
