Lets several AHV VMs work from one NVIDIA graphics processor at the same time, by giving each guest its own slice of the physical GPU.
Also called virtual GPU.

Each book explains vGPU in context, with comparison tables and the common traps.
Terms in this definition
- Nutanix AHV
The hypervisor from Nutanix. Veeam's integration backs up its VMs to repositories and can restore to it from backups of vSphere, Hyper-V, AHV and other platforms.
- Virtual machines
Infrastructure-as-a-service compute giving complete control of the operating system, making it a fit for lift-and-shift moves and for software relying on OS-level pieces like COM.
- Physical
Describes the concrete, real-world parts that put a logical architecture into effect.
- GPU
A graphics processing unit, an accelerator suited to highly parallel work like graphics and AI. Azure offers them in the NV and NC VM series.
Related terms
- GPU
An accelerator built for massively parallel work such as graphics, AI and ML. AHV either dedicates a physical one to a single VM by passthrough or splits it between VMs with vGPU.
- GPU pass-through
Hands a whole physical GPU straight to a single AHV VM. Such a VM cannot live migrate and cannot also have a vGPU.
- Hot add
Gives a VM more memory, CPU or disk while it stays powered on. GPU and vGPU configuration and IDE disks are excluded, and CPU changes rely on the guest OS.
- RDP
Protocol for remote Windows sessions. Installing a vGPU driver normally cuts a VM off from the Prism console, so put this or something like it in place beforehand.
