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.
