[ovirt-users] Error on Adding Host

Hi folks. I think I have been hit by the most annoying error you can get on oVirt. I have removed a Host from Engine, re-installed it with the latest ovirt-node-ng ISO, tried to add the freshly installed Host back to Engine and got the following error: "Command returned failure code 1 during SSH session" The host has the same FQDN as before and I have cleaned the SSH from the known_hosts file in the Engine before trying to add it on the web interface. I have also tried this process with 2 different ISO files: - ovirt-node-ng-installer-ovirt-4.1-pre-2017030911.iso - ovirt-node-ng-installer-ovirt-4.1-pre-2017031104.iso And the Engine is version 4.1.1.4-1 Have searched for this error and there are a lot of people affected but not a single solution solves it. Please give some light. Thanks Fernando
