Hello,
Hmm, according to the chart on this page, if I am reading this correctly, you may not be able to activate Server 2025 vm on a server 2022 host:
https://learn.microsoft.com/en-us/windows-server/get-started/automatic-vm-activation?tabs=server2025Also seems to state you need Datacenter to use AVMA activation.
AVMA requires a Windows Server Datacenter edition with the Hyper-V server host role installed. The Windows Server version of the host determines which versions it can activate in a guest VM. The following table lists the guest VM versions that each host version is able to activate. A host version can access all the editions (Datacenter, Standard, or Essentials) of its eligible guest VM versions.
