Compatibility Requirements for the NVIDIA vGPU Manager and Guest VM Driver#
The releases of the NVIDIA vGPU Manager and guest VM drivers that you install must be compatible. If you install an incompatible guest VM driver release for the release of the vGPU Manager that you are using, the NVIDIA vGPU fails to load.
See VM running an incompatible NVIDIA vGPU guest driver fails to initialize vGPU when booted.
Note
You must use NVIDIA License System with every release in this release family of NVIDIA vGPU software. All releases in this release family of NVIDIA vGPU software are incompatible with all releases of the NVIDIA vGPU software license server.
Compatible NVIDIA vGPU Manager and Guest VM Driver Releases#
The following combinations of NVIDIA vGPU Manager and guest VM driver releases are compatible with each other.
NVIDIA vGPU Manager with guest VM drivers from the same release
NVIDIA vGPU Manager with guest VM drivers from different releases within the same major release branch
NVIDIA vGPU Manager from a later major release branch with guest VM drivers from the previous branch
NVIDIA vGPU Manager from a later long-term support branch with guest VM drivers from the previous long-term support branch
Note
When NVIDIA vGPU Manager is used with guest VM drivers from a different release within the same branch or from the previous branch, the combination supports only the features, hardware, and software (including guest OSes) that are supported on both releases.
For example, if vGPU Manager from release 19.6 is used with guest drivers from release 16.4, the combination does not support Windows Server 2019 because NVIDIA vGPU software release 19.6 does not support Windows Server 2019.
The following table lists the specific software releases that are compatible with the components in the NVIDIA vGPU software 19 major release branch.
NVIDIA vGPU Software Component |

Incompatible NVIDIA vGPU Manager and Guest VM Driver Releases#
The following combinations of NVIDIA vGPU Manager and guest VM driver releases are incompatible with each other.
NVIDIA vGPU Manager from a later major release branch with guest VM drivers from a production branch two or more major releases before the release of the vGPU Manager
NVIDIA vGPU Manager from an earlier major release branch with guest VM drivers from a later branch
The following table lists the specific software releases that are incompatible with the components in the NVIDIA vGPU software 19 major release branch.
