Issue/Introduction
Unable to add NVIDIA vGPU as a PCI device to a Windows 11 VM. There are existing virtual machines working with the similar setup .
It is not a Nested Virtualization environment, and GPU is not configured as Passthrough device on ESXi Hosts in vSphere Cluster.
Plus, it may be displayed as error "VVTD (Intel Virtualization Technology for Directed I/O) is not supported on a virtual machine with vGPU device" instead of "The use of a virtual IOMMU is not supported on this virtual machine with a vGPU device".
Environment
VMware vSphere ESXi 7.x , 8.x
VMware vCenter Server 7.x , 8.x
Virtual Machine Guest OS Windows 2019
Virtual Machine Guest OS Windows 11
Cause
In Windows 11, Virtualization-based Security (VBS) is enabled by default and this requires Virtualization-based security (VBS) is a security feature in Windows that isolates system components in a virtualized environment to enhance protection against malicious code and attacks.
Virtualization-based Security (VBS) leverages hardware virtualization and Input/Output Memory Management Unit (IOMMU) features to enhance protection of critical system components by enabling isolation of hardware like GPUs.
Resolution
Uncheck the box to disable VBS under VM options and then disable Hardware virtualization and I/O MMU features under CPU settings of the VM.
Add vGPU device to the VM and Power-On. See Add an NVIDIA GRID vGPU to a Virtual Machine.
