Hello
Thank you for your question and reaching out. I can understand you are having issues related to Microsoft SPLA .
As you mentioned that you have Datacenter 2016 License , you can use AVMA keys
Track virtual machine usage and licenses from the virtualization host, without requiring any access rights on the virtualized systems
Service Provider License Agreement (SPLA) partners and other hosting providers do not have to share product keys with tenants or access a tenant's virtual machine to activate it. Virtual machine activation is transparent to the tenant when AVMA is used. Hosting providers can use the server logs to verify license compliance and to track client usage history.
