Enable GPU Virtualization in OpenStack
Nowadays, GPUs have become much more powerful while being energy efficient. With the rise in popularity of 3D applications, growth in Big Data analytics, High Performance Computing, and streaming video, GPUs are being pressed into service to gain performance. Traditionally in virtualization usages, a physical GPU is allocated to a VM using PCI device pass-through, an approach that limits resource sharing. However, graphics virtualization support today enables GPU sharing on par with CPU sharing
