Moti, Thank you very much for such a clear explanation. At this time I've solved the problem via network infrastructure. I've explained before that as this is a production environment, I won't risk to have unstable behavior. Anyway, I know that ovirt team is working hard to enhance network capabilities, but until then, I guess I'll keep getting the features I need by changing network topology and using network tools. Regards,
