I'm reading the documentation here : http://www.ovirt.org/documentation/admin-guide/serial-console-setup/ After a few strace, I found the ssh configuration used for the custom ssh that listen on port 2222: /usr/share/ovirt-vmconsole/ovirt-vmconsole-proxy/ovirt-vmconsole-proxy-sshd/sshd_config And I have a big problem with it. It says "GSSAPIAuthentication no" but public key authentication is not allowed in my data center, we use kerberos every where. So I wonder if I can edit this file ? How is it managed by ovirt ? I can always use puppet to modify just this line, it will be fine for me. The point 4 in Automatic Setup is not very helpfull: " • once the setup succesfully run, and once ovirt-engine is running, you can log in and register a SSH key. (TODO: add picture)" what does it mean ?
