New page

This page list information I found while trying to answer the question: "Can multiple virtual machins share a single GPU?"

* The new Nvidia VGX platform is notable for allowing multiple users to share a GPU on their virtual desktops.
<pre>
[...]
Huang said during the keynote that Nvidia had been working on this GPU virtualization solution for five years. The VGX platform enables every virtual machine to have a GPU
[...]
While he noted that putting a GPU into a virtual machine isn't new, what is new is the ability to share that GPU with multiple virtual machines.

* GPU Virtualization on VMware’s Hosted I/O Architecture
<pre>
[...]
GPUs pose a unique challenge in the field of virtualiza- tion. Machine virtualization multiplexes physical hardware by presenting each VM with a virtual device and combin- ing their respective operations in the hypervisor platform in a way that utilizes native hardware while preserving the illusion that each guest has a complete stand-alone de- vice. Graphics processors are extremely complicated devices.
[...]
Thus, it is nearly intractable to provide a virtual device corresponding to a real modern GPU. Even starting with a complete implementation, updating it for each new GPU generation would be prohibitively laborious. Thus, rather than modeling a complete modern GPU, VMware’s
primary approach paravirtualizes: it delivers an idealized software-only GPU and our own custom graphics driver for interfacing with the guest operating system
