Satellite 6 and RHEV

Latest response

Hello.

I am trying to understand how to setup RHEV virtual machines hosted on RHEV-H 6 hosts (not RHEL 6) to receive updates from Satellite 6 server.

There are some discussions and articles available here and there suggesting to use virt-who service to discover RHEV-H <-> VM relationships. I am quite confused on this matter because I do not know really where this virt-who should work (RHEV-H or one of VMs) and why I need it since Satellite 6 has build-in mechanism to discover the RHEV-H <-> VM relationship and (Compute Resource).

So for now my questions are:
Does this "virt-who stuff" only relate to virtual Data Center Subscriptions for RHEV-H hosts?
Do I need one virt-who per hypervisor or one per RHEV data center?
Why can't we use compute resource information gathered by Satellite 6 to build RHEV-H <-> VM relationship for subscription management?
Is there anywhere a complete guide explaining all this matters?

For reference here are links to documents that confuse me:

  1. https://access.redhat.com/documentation/en-US/Red_Hat_Subscription_Management/1/html-single/RHSM/index.html#register-virtual
    "The hypervisor is registered first, and then a related process on the system scans for any guests and submits the discovered UUIDs to the subscription service. This is done by the virt-who process on the hypervisor."

  2. https://access.redhat.com/solutions/1272733
    "1) Configure virt-who on any one virtual machine on each hypervisor and attach separate VDC subscription."

  3. https://access.redhat.com/documentation/en-US/Red_Hat_Satellite/6.0/html-single/User_Guide/index.html#appe-Glossary_of_Terms
    "A Compute Resource is virtual or cloud infrastructure, which Red Hat Satellite 6 uses for deployment of hosts and systems. Examples include Red Hat Enterprise Virtualization Manager, OpenStack, EC2, and VMWare."
