Actual results:
Guest hasn't auto subcribe the existed bonus pool "Red Hat Enterprise Linux for Virtual Datacenters, Standard (DERIVED SKU)". it will auto attach another bonus pool which generated by hypervisor auto subscribe another physical pool.

Expected results:
Guest shouldn't auto attach another pool, it should auto attach the existed bonus pool "Red Hat Enterprise Linux for Virtual Datacenters, Standard (DERIVED SKU)" since this bonus pool also covered the product "Red Hat Enterprise Linux Server".
