Comment 2 Keith Robertson 2012-07-09 16:15:08 EDT
The root cause of this problem is that your installer (or your config) hasn't properly set up public/private key authentication between the Engine and the node.  You can easily confirm this with the following SSH command.  If you execute the command and are prompted for a PW then you know that public/private key auth is not working.  

Further, if you are prompted for a PW then you shd know that this is not a LC problem.  It is an installer problem or an engine problem.  The LC will manifest the problem by prompting you for a PW but it is not the source of the problem.

ssh -i /etc/pki/ovirt-engine/keys/engine_id_rsa root@<node here>
Comment 3 Kiril Nesenko 2012-07-11 10:59:49 EDT
Closing the bz. Issue was on my local machine.
Comment 4 Kiril Nesenko 2012-08-02 08:26:07 EDT
I still can reproduce this on si13 build. log-collector promts for passwords and this command doesn't works for me.

[root@vm-17-5 yum.repos.d]# ssh -i /etc/pki/ovirt-engine/keys/engine_id_rsa root@nari11.eng.lab
root@nari11.eng.lab's password:

As Keith said in  Comment 2 , seems like public/private key authentication wasn't set up.
Comment 6 Barak 2012-08-26 09:14:33 EDT
There are 2 ends for above public/private auth isse:
1 - rhevm-setup that produces the host SSH keys
2 - vdsm_bootsrap that configures the host to allow the ssh key-pair access
Comment 7 Alon Bar-Lev 2012-08-27 08:59:04 EDT
Hello Kiril,

How did you install the nari11.eng.lab node?

Can you please check if ~root/.ssh/authorized_keys has anything and/or the correct public key?

Public key can be acquired using:

 # ssh-keygen -y -f /etc/pki/ovirt-engine/keys/engine_id_rsa

Comment 8 Kiril Nesenko 2012-09-04 05:45:48 EDT
Alon, I tested it once again and it works. Key was copied to the host and log-collect does not promts for a password any more.
