[ovirt-users] Error on Adding Host

[FERNANDO FREDIANI]

Final information about this.

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.

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 ?

Let me know if you need anything further about this.

Regards
Fernando
