[Users] Host installation failed. SSH session closed during connection (ovirt-node-iso-3.0.3-1.1.fc19)

[Udaya Kiran P]

Hi Alon,

I am currently setting up a non ovirt-node host on a different machine on Fedora 19.

I haven't changed sshd settings. 

I remember executing setenforce 0. Would that cause this issue?

I am planning to re-install oVirtNode (same 3.0.3 fc19 ISO), Please let me know if you have any suggestions.


Regards,
Udaya Kiran

This is strange!!!!!
You do not have PK at all.
Does it happen for all hosts or just this particular one? Can you please try other non ovirt-node hosts?
I still think that something was altered at sshd at host side, or there is something wrong with ovirt-node image.
