RHEL 6.6 RHEV-M installation problem

Good day!

I have a little problem with installation RHEV-M.
I have 30 Day Red Hat Enterprise Linux Server Self-Supported Evaluation and 60 Day Self-Supported Red Hat Enterprise Linux with Smart Virtualization and Management Evaluation

i do this

subscription-manager register - OK
subscription-manager list --available | grep -A8 "Red Hat Enterprise Linux Server" -ok I see pool ID
subscription-manager attach --pool=pool_id -OK
BUT when i use subscription-manager list --available | grep -A8 "Red Hat Enterprise Virtualization" i don't see anything.

As a consequence, I can't subscribe to the required repositories.

What am i doing wrong?
Thanks!
