But that is exactly the problem. I can access the vm via vnc(from sunstone), but get login screen(local host login/password which I don't know). So, I can't check for daemons. I read online that for the images created for kvm/opennebula access is done via ssh(passwordless).
Because the image I am using is prebuilt for opennebula, I imagine something is wrong in my controller/node configuration, but do not know where to look.
