Need advice on a cluster of 2 servers 2012 r2

Hello!
There are two physical servers, there are 2 srv2012 R2 Std OLP licenses.
There are no more servers and never will be. There is no hardware SAN either.
The task is to create a failover cluster and run 2 Hyper-V virtual machines in it.
What I tried to do:
1. Put the OS on physical servers. Added roles Hyper-V, DNS.
2. Made the 1st PDC server, and the other - add. controller.
3. As a SAN, I used StarWind software (installed on both servers, set up a "cluster" or as it is correctly called from two SANs, i.e. "HA" on two nodes).
4. Gave the role of failover clusters nat. servers. Began testing before deployment of a cluster - a problem with AD. Looked through the Internet. I saw that in the srv2012 environment (unlike the same 2008), you cannot combine the roles of a domain controller and a cluster member on the same server (in the same OS). By the way, as I understand it, you created the planned configuration (the question is on what version of the OS?), a quote from itband.ru: "In my projects, if I have a small branch office, where there are only two physical nodes that I want to make members of the cluster Hyper-V, I make them physical controllers - and cluster members at the
same time. This is a supported configuration, although it has some difficulties. "
What to do?
I see this option: outside the cluster in the Hyper-v environment, create VMs on each of the physical. servers. On the 1st VM, deploy the PDC, and on the 2nd - add. controller. Thus I do not know - to enter physical. servers (hosts) to the domain or not (I read that a domain is not required for a cluster on srv2012).
In this case, only 1 srv2012 VM will work in the cluster (because the server 2012 standart license - 2 VMs in total).
What is your opinion, how would it be more competent to solve the task on the existing equipment?
Thanks in advance.

In general, you should not do this, because all deviations from best practice go sideways.
... but if you really want to:
1. take another computer, create 2 virtual machines on them, raise the main and backup AD controller.
2. Set up 2 HV servers, enter into a domain
3. Create a cluster (where will you store the quorum?)
4. Drag and drop controllers to HV servers
5. Set up asymmetric priority of AD controllers on HV servers

About the same problems. Two servers, how can you make fault-tolerant storage for virtual machines (something like vSAN and Virtual Storage Appliance from VMware)? win2012r2
