RHV Manager extra RHEL needed

Hi do I need to purchase an extra RHEL for RHV Manager if I purchase RHEV?

Example:
3x RV0236407 for one cluster with 1 RHV Manager

quote from pricelist notes:
Note: A RHV subscription is not needed for any server or virtual machine that will run the RHV Manager. However, RHV Manager requires an operating system. Therefore, the customer needs a RHEL subscription to attach to the server or virtual machine that will run RHV Manager.

Note: There is a known issue when the customer wants to deploy RHV Manager on a standalone server. If your customer intends to do that, open a BU Guidance ticket.

Thank you

Matthias
