Error subscription during RHEV-M Installation

I'm following the guidelines from page 3.3. Subscribing to the Red Hat Enterprise Virtualization Channels
3.3.1. Subscribing to the Red Hat Enterprise Virtualization Manager Channels using Subscription Manager

However, I'm getting following results;

[root@rhevmch ~]# subscription-manager list --available | grep -A8 "Red Hat Enterprise Linux Server"
[root@rhevmch ~]# subscription-manager list --available | grep -A8 "Red Hat Enterprise Virtualization"
[root@rhevmch ~]# subscription-manager list --available | grep -A8 "JBoss Enterprise Application Platform"
[root@rhevmch ~]# yum-config-manager --enablerepo=rhel-6-server-rhevm-3.1-rpms
Loaded plugins: product-id, refresh-packagekit
Error getting repository data for rhel-6-server-rhevm-3.1-rpms, repository not found

FYI, this is my active subscription: 30 Day Red Hat Enterprise Linux Server Self-Supported Evaluation

Please help

thanks.
