AVMA can help in the ever-evolving world of IT, where managing software licenses across virtual machines (VMs) can be a daunting task, especially when dealing with offline devices. Traditional methods like Key Management Services (KMS) or Volume Activation Services (VAS) have served us well, but they come with limitations, particularly in disconnected environments. Enter Automatic Virtual Machine Activation a streamlined, efficient alternative that simplifies activation while addressing the unique challenges of offline devices.

The Challenge with Offline Devices
Offline devices, by their very nature, lack direct internet connectivity, making traditional activation methods cumbersome. KMS, for instance, requires a Volume License Service / KMS host server within the network, and devices must periodically connect to this server to maintain activation. This dependency on network connectivity can be a significant hurdle for isolated or remote environments.
Why it is a Game-Changer
AVMA is designed with simplicity and flexibility in mind, making it an ideal solution for activating VMs in both connected and disconnected environments. Here’s why Automatic Virtual Machine Activation stands out:
No Internet Required: Unlike KMS, Automatic Virtual Machine Activation does not rely on network connectivity for activation. It binds the VM activation to the licensed Hyper-V host, ensuring that VMs are activated automatically when they start up, regardless of their internet status.
Streamlined Management: With AVMA, there’s no need to manage individual product keys for each VM. The activation process is transparent and seamless, reducing administrative overhead.
Enhanced Security: AVMA eliminates the need to share product keys with tenants or access their VMs for activation. This not only simplifies the process but also enhances security by minimizing exposure to sensitive information.
Flexibility Across Versions: Automatic Virtual Machine Activation supports a wide range of Windows Server versions, ensuring compatibility and ease of use across different environments.
Real-Time Reporting: For IT administrators, AVMA provides real-time reporting on VM usage and license compliance, offering valuable insights without requiring access to the VMs themselves.
AVMA vs. KMS: A Comparative Look
| Feature | AVMA | KMS |
|---|---|---|
| Internet Dependency | Not required | Required for periodic activation |
| Key Management | No individual keys needed | Requires managing KMS host and keys |
| Security | No key sharing with tenants | Keys may need to be shared |
| Compatibility | Broad support for Windows Server VMs | Limited to network-connected devices |
| Ease of Use | Automatic and transparent activation | Requires setup and maintenance |
Practical Applications
AVMA is particularly beneficial for:
- Remote Locations: Activate VMs in isolated environments without the need for network connectivity.
- Service Providers: Simplify activation for hosting providers without exposing product keys.
- Failover Clusters: Ensure consistent activation across clustered Hyper-V hosts.
System requirements
The prerequisite for AVMA is a Windows Server Datacenter edition with the Hyper-V server host role installed. The versions that can be activated in a guest VM are determined by the Windows Server version of the host. The Guest VM versions that each Host version can activate are listed in the following table. A host version has access to all editions (Datacenter, Standard, or Essentials) of its eligible guest VM versions.
| Server host version | Windows Server 2025 guest VM | Windows Server 2022 guest VM | Windows Server 2019 guest VM | Windows Server 2016 guest VM | Windows Server 2012 R2 guest VM |

How to activate AVMA on a Guest VM
Once you’ve got Windows Server up and running on your virtual machine, it’s time to activate it using an AVMA key. Just open an elevated Terminal Session, then enter:
slmgr /ipk <AVMA_key>As long as your virtualization host is already activated, your VM will seamlessly activate itself—no extra steps needed.
To speed up and verify your license activation you can try these two commands:
#### manually activate Windows using the current license key ####
slmgr /ato
#### display Windows license information ####
slmgr /sliAzure Stack HCI and AVMA
