I would like to build a Windows 10 Pro HyperV farm with many little Linux based routers for dedicated IPsec tunnels. Doing some digging around and unable to find information on properly licensing Windows 10 Pro Hyper V im curios if this forum can point share some links that breaks down licensing for Windows 10 HyperV with Linux OS. I know I need the OS license of course and then from what I can tell device cal for each VM I add.
Another question would be. The linux OS can run with 1 core and 256 kb of ram, is there a limit on how many I can add? I've seen in various website that you can build up to 1024 (<- seems nuts). I have successfully built a 2019 HyperV Server with four routers in a nested hyperV and it worked great until troubleshooting 2019 OS and the fact it is EOL. 2019 Pro only legally allows a few VM's and Datacenter is pretty expensive. Is it illegal to build 1024 host in Windows 10 in a business?
POC of running in non production Windows 10 HyperV with a Nested Windows 2019 HyperV with 4 public facing routers.

For that one read on here.

Just checking if there's any progress or updates?

Is there a simple answer to the question, how many Linux OS can I run on a windows 10 pro computer? From what I can tell, since self hosted I can build 4.

There is no licensing limit for a free OS. Hyper-V doesn't really have VM limits, other than your hardware (RAM, disk space, etc)
For each Windows 10 VM you're running, you need a Windows 10 license...the 4 VM limit is for a specific type of licensing with Software Assurance.
As long as you're accessing your Windows 10 VMs locally...you're at the host computer and not remotely accessing the VMs, all you need is a retail license.
Want to run 6 VMs, get 6 Windows 10 licenses.
That was useful. So now I'm curious which license to get for each vm. Is there Windows 10 device CALs, or another Windows 10 license or will say 2019 Device CAL work with windows 10?
You need an actual Windows 10 OS license. A device CAL is not a Windows OS license, it's the "license" that lets you access a Windows Server. If you're running your Win10 VMs and they also need access to your Windows server, you'd also need a device CAL for each VM.
There are no Windows 10 device CALs

"If the workstations in your organization are networked, you likely depend on network server software to perform certain functions, such as file and print sharing. To access this server software legally, a Client Access License (CAL) may be required. A CAL is not a software product; rather, it is a license that gives a user the right to access the services of the server."
