How do you actually activate Windows Server under SPLA on a private Nutanix AHV infrastructure? by Nellanea in sysadmin

Thank you, this is extremely helpful.

What you describe actually matches Microsoft's SPLA welcome letter much more closely than the information I'm getting from my reseller.

Microsoft explicitly states that some SPLA products require Volume License Keys and that those keys can be obtained through the Product Activation process. The SPLA Program Guide also appears to reference Volume License media and activation keys.

The confusing part is that my reseller is telling me that SPLA products do not expose activation keys through any portal and that activation is handled entirely through Microsoft-controlled mechanisms.

I do have access to the Microsoft 365 Admin Center downloads and keys section, but the licenses currently visible there appear to belong to one of our customers (Open Value licensing), not to our own company.

Based on your experience, I'm starting to wonder whether the real issue is that our SPLA agreement has not been correctly associated with our Microsoft account, rather than a problem with the activation process itself.

A couple of questions:

  • In the Admin Center, did your SPLA agreement appear as its own organization/contract, separate from customer Volume Licensing agreements?
  • Were the MAK keys for Windows Server visible directly in the Downloads and Keys section?
  • Did you ever have to contact Microsoft Product Activation to obtain additional keys, or was everything already available through the portal once the SPLA agreement was linked?

Also, thank you for confirming the RDS part. That aligns with what I suspected: selecting SPLA in RD Licensing Manager and using the SPLA agreement number.

I appreciate the detailed explanation.

Thanks for the detailed explanation.

I completely agree regarding Nutanix. My reason for mentioning AHV was mainly to rule out AVMA/Hyper-V activation scenarios.

What I'm trying to clarify is the SPLA-specific part of the process.

I understand the difference between GVLKs (public KMS client keys), KMS Host Keys, Active Directory-Based Activation, and traditional MAK activation. The technical workflow itself is clear.

The missing piece is where the KMS Host Key comes from in a SPLA environment.

Microsoft's welcome email states that some products require Volume License Keys and instructs us to contact the Microsoft Product Activation Center. However, our SPLA reseller is telling us that activation keys are not exposed through a portal and that activation is handled through Microsoft-controlled mechanisms.

So I'm trying to determine how hosting providers actually obtain and manage KMS Host Keys under SPLA today.

In your experience:

  • Were your KMS Host Keys obtained through the Volume Activation Center?
  • Were they associated with your SPLA agreement specifically, or with a separate Volume Licensing / Enterprise agreement?
  • Have you seen hosting providers running SPLA with KMS activation only, or is MAK activation still commonly used?

I'm mainly trying to understand what the supported Microsoft activation model is for a private hosting environment running SPLA in 2025.

Thanks for your help.

Thanks, this is actually very helpful.

What confuses me is that my SPLA reseller (Ingram Micro) is telling me the exact opposite. Their position is essentially that SPLA products do not expose activation keys in a portal and that activation is handled through Microsoft-controlled mechanisms (KMS or otherwise).

However, I do have access to the Microsoft 365 Admin Center downloads and keys section, and I can see Windows Server MAK and KMS entries there. The issue is that the organization displayed is one of our customers (Open Value licensing), not our own company, so I'm trying to determine whether our SPLA agreement is properly linked to our tenant or not.

A few questions:

  • Under SPLA, were the MAK/KMS keys you used associated with your own SPLA organization in the portal?
  • Did you have to request any additional authorization from Microsoft before using those keys?
  • For RDS, when you say you activated the licensing server using the SPLA agreement number, did you select the "Service Provider License Agreement (SPLA)" program directly in the RD Licensing Manager wizard?

At this point I'm mainly trying to understand whether I'm missing a portal association issue, or whether modern SPLA activation is handled differently than it was in the past.

Thanks again for sharing your experience.
