Hi Ruben,
We have successfully tested the Oracle VM with OpenNEbula. As per my below mail will it be better to have ssh -t option instead of ssh -n in one-ssh file to execute script file in cluster node to get the information.
Note: The reason is Oracle VM Cluster node machine configured in sudors with "Default requiretty". which is not allowing the commands to be executed over ssh using -n option.
If yes, do I need to raise any ticket in openNEbula trac.
I believe there is no documentation to debug information manager, virtual machine manager and transformation manager scripts through command line.
Shall I include following my findings to debug the scripts in openNEbula site? it will be better for other people. let me know how can I include the debug setups
Regards

Yesterday itself i found the issue. one-ssh file fires the commands using ssh -n option.
The Oracle VM host machine configured in sudors with "Default requiretty". which is not allowing the commands to be executed over ssh using -n option.
So i comment that line in sudors file. now it is working fine.

Hello,
Try to issue this command:
$ ssh 10.101.102.113 /tmp/ne_im_scripts/
ne_im-5c403641cf6491ea9093adae9ec4a2fe
It will give you more information about what is happening. Make sure
that ruby is installed in the remote host.
Bye
