<p>Final information about this.</p>
<p>I have re-installed the node with the ISO Release version
(2017020112) and it now worked, both with SSH port 22 or changed.
Therefore Node-NG ISO versions 2017030911 and 2017031104 don't
work well with my Engine.<br>
</p>
<p>Despite it was still not able to fetch the fingerprint using
running with a different port on SSH (and firewalld allowing the
port) it was able to add the host normally and configure it
correctly. Should I report it in bugzilla ?<br>
</p>
<p>Let me know if you need anything further about this.</p>
<p>Regards<br>
Fernando<br>

<p>Hello Yedidyah and all<br>
</p>
<p>I bring you a slightly new information about this issue. <br>
</p>
<p>If I have the node SSH port changed to something else other
than 22 it is unable to fetch the fingerprint. I changed it
back to 22 and it worked to fetch the fingerprint but failed
again when adding the host with the same error as before.
(Yes I have allowed the port in the node firewall)<br>
</p>
<p>Before adding the host I have also cleaned both
/root/.ssh/known_host and
/var/lib/ovirt-engine/.ssh/known_hosts<br>

on most sites about this subject but still can't find
anything that points to the error (find the related logs

<br>
Please note that before adding the server the Engine is not
able to fetch the fingerprint and thorws the following error
in the log: <br>

<br>
I think I have been hit by the most annoying error you
can get on oVirt. <br>
I have removed a Host from Engine, re-installed it with
the latest <br>
ovirt-node-ng ISO, tried to add the freshly installed
Host back to Engine <br>
and got the following error: <br>
<br>
"Command returned failure code 1 during SSH session" <br>
<br>
The host has the same FQDN as before and I have cleaned
the SSH from the <br>
known_hosts file in the Engine before trying to add it
on the web interface. <br>
<br>
I have also tried this process with 2 different ISO
files: <br>
- ovirt-node-ng-installer-ovirt-<wbr>4.1-pre-<a
moz-do-not-send="true" href="tel:%28201%29%20703-0911"
value="+12017030911" target="_blank">2017030911</a>.iso
<br>
- ovirt-node-ng-installer-ovirt-<wbr>4.1-pre-<a
moz-do-not-send="true" href="tel:%28201%29%20703-1104"
value="+12017031104" target="_blank">2017031104</a>.iso
<br>
<br>
And the Engine is version 4.1.1.4-1 <br>
<br>
Have searched for this error and there are a lot of
people affected but not <br>
a single solution solves it. <br>
<br>
Please give some light. <br>

Please check/share /var/log/ovirt-engine/engine.<wbr>log
