License confusion, unsure what I need

Some help would be appreciated as I'm completely confused on what I need in terms of licensing.

We're a public University in the USA and I'm trying to run a copy a RHEL 6.9 as a VM on a system that has a single socket. The host system is Hyper-V which is already licensed. All I need is updates support, I don't need the ability to call in or make support tickets.

I've seen the RH licensing on their website, the various licenses on CDWG, whitepapers talking about Academic Discount pricing, I got a trial of the RHEL Workstation license and my RHEL Server consumed it as an available license for testing... I'm just confused and not sure what my actual options are.
