Are windows CAL's required for Linux VM's on a windows Hyper-v host?

On my Windows Server 2012 Hyper-v host machine, If I create a VM and install a Linux file or terminal server, do I need to purchase Windows CAL's for the users who access the Linux VM? Are those Linux VM users accessing the Windows server even though they are not accessing a Window virtual desktop?

Microsoft Client Access Licenses are only required to Access Microsoft Windows resources! (File and Print)

If you are offering Linux File and Print, no CALS required.

But do you not have any other Windows resources on your LAN, that your clients needs Windows CALs for?

or is this a method to avoid purchasing Windows CALS

Way to avoid CAL's. We only have 3 servers. The other two are Linux. I have this new server with 2012 installed and it is no being used. It is being wasted.  Not my plan. I came in after this environment was setup. I may need to setup a terminal server/RDH type server at some point. I'd love to setup a 2012 Gateway server to serve up a virtual application to about 10 users.  If I go that route, I will need User MS Cals. If I install Linux in a VM I can use a non-microsoft virtual app setup and avoid the extra MS Cals.

Correct, because you will need TS/RDS CALS, and CALS for Microsoft Client Access.

If all Linux - none required, if accessing non-Microsoft OS.
10 Tips to Protect Your Business from Ransomware

A couple more questions: If I have two Microsoft servers, and I have 10 users who will access shared files on both servers. Do I need 10 Client Access CALS or 20 (2 for each user)?

When you purchase CALS, do they need to be renewed (repurchased) each year?
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
CALs do not expire. So they are valid forever.

User CALS allow users to access resources in your Domain.

So, 10 is all you need.
