			== About Open-IOV ==
			Open-IOV runs unmodified NVIDIA driver stacks inside virtual machines with GPU compute on hardware you own — no proprietary vGPU license, and no patches to the guest driver, the host driver, the hypervisor or the firmware. The project adds one host kernel module (<code>vgsp.ko</code>) that implements the interface the guest driver expects to talk to — the GPU System Processor and its resource-manager firmware — and arranges for the guest's work to run on real GPU hardware.

	~~Welcome to the~~ '''Open-IOV ~~Project~~''' ~~wiki~~.		__NOTOC__
			<div style="border:1px solid #c8ccd1; background:#f8f9fa; padding:0.9em 1.2em; margin-bottom:1em;">
			'''Open-IOV''' is an open-source virtualization layer for NVIDIA GPUs: it runs '''stock, unmodified NVIDIA drivers inside virtual machines''' — Linux and Windows — with CUDA on hardware you own, '''without proprietary vGPU licenses''', without patching the guest driver, the host driver, the hypervisor or the firmware.
