I'm failing to install hosts on o-s-t on Master.
What worries me is not that I'm failing (though it is a bit of a surprise, perhaps something I've done?), but that there are no logs around it.

Please see my response below, but which logs are you

missing?

/var/log/ovirt-engine/host-deploy is empty and so is /var/log/ovirt-engine/ansible.

Logs for both part of host installation (host-deploy and ansible) are

in /var/log/ovirt-engine/host-deploy, but they are created once each part successfully started.

All I'm seeing:
Host lago-basic-suite-master-host-0 installation failed. Unexpected connection termination.

So this means that SSH connection to the host using which the host deploy should be started failed. The reason is above in server.log, that SSH connection timed out. This error appears even before host-deploy is executed, that's we don't have any host-deploy log created.
