Error GPU-supported virtual machine cannot be powered on?

SteveWKC Lv1  Posted 2026-Oct-14 10:08

my user get the following error message Failed to power on the desktop. Cause; [PrivateVDI0011]: License check failed. GPU-supported virtual machine cannot be powered on, because the number of GPUs used by this cluster exceeds the licensed number (6). Please contact Sangfor Technologies techni...

anyone know what happened. how to classify as GPU=supported machine, which feature do need additional license.  Thanks all for your help

Failed to power on the desktop. [PrivateVDI0011]: License check failed. GPU-supported virtual machine cannot be powered on, because the number of GPUs used by this cluster exceeds the licensed number (6).Root Cause:
Your cluster is licensed for only 6 GPUs. You already have 6 GPU-enabled VMs powered on. This VM Win11_Chinese(Privat...) - PrivateVDI0011 would be the 7th, so the license check blocks it.
It's not a hardware problem, it's a license limit.
How to fix - pick one:
1. Quick fix - free up a license:
Go to aDesk Management > Desktop Pool / Private Desktops
Check how many VMs have GPU / vGPU enabled and are Powered ON.
Power OFF or Remove GPU from an unused VM, then power on this Win11 VM.
Run this check:javascriptPrivate Desktops > Filter by GPU = Yes > Sort by Power State = ON

This error is most likely a Sangfor VDI GPU licensing limit issue, not a Windows 11 problem.

The message PrivateVDI0011 says the cluster has exceeded its licensed GPU-supported VM capacity. The license currently permits 6 GPUs, but the cluster's GPU license usage is above that limit. Sangfor's VDI documentation distinguishes standard 2D desktops from 3D/GPU-enabled desktops and identifies separate licensing requirements for GPU features.

1. What makes a VM GPU-supported?
A VM is generally considered GPU-supported when its configuration uses one of these features:

vGPU: A virtual GPU profile, such as an NVIDIA GRID B-series or Q-series profile, is assigned to the VM.

GPU passthrough: A physical GPU is assigned directly to the VM.

3D desktop acceleration: The desktop is configured to use Sangfor's GPU/3D virtualization capabilities.

A VM does not necessarily become GPU-supported just because the physical host has a GPU installed. Check the VM's actual graphics configuration.

2. Which license or feature may be required?

Feature                                                Sangfor VDI licensing

Standard 2D desktop                                Silver user license
3D desktop using B-series vGPU                        Golden user license + NVIDIA vPC license
3D workstation using Q-series vGPU                Platinum user license + NVIDIA vDWS license
GPU passthrough                                        Platinum user entitlement for the documented VDI feature


These requirements are described in Sangfor's official VDI feature comparison .

Important: The error mentions a cluster limit of six GPUs. This may refer to a specific Sangfor GPU entitlement or resource limit, so do not assume that purchasing additional NVIDIA licenses alone will resolve it.

3. How to troubleshoot
Check the affected VM configuration. In the Sangfor management console, open the VM's hardware settings and check whether a vGPU profile or GPU passthrough is assigned. Also check its 3D/GPU settings.

Check cluster GPU license usage. Review the relevant licensing page and compare the licensed capacity with the GPU resources currently allocated to VMs. Look for VMs that were deleted, reconfigured or migrated but may still be consuming a license.

Check VDC user licensing. Verify that the affected desktop's user/license category supports its configured GPU mode.

Review the NVIDIA license if vGPU is enabled. Confirm that the NVIDIA license type matches the GPU profile. Sangfor's troubleshooting guidance maps B-series to Virtual-PC and Q-series to Virtual-WS licensing.

If the VM should be 2D-only, verify whether GPU settings were accidentally enabled or inherited from a template. Remove the GPU assignment only if the workload does not require it and your configuration permits it.

4. To identify the exact cause
Could you share these three details?

Sangfor VDI version: for example, 5.9.x
Platform: HCI/aSV or another virtualization platform
GPU configuration of this VM: vGPU, GPU passthrough, or no GPU intentionally configured

With those details, I can help narrow down whether this is a Sangfor cluster GPU license limit, a VDC Golden/Platinum entitlement issue, or an NVIDIA vGPU licensing mismatch.
