Intel SR-IOV Explanation

Simple (hopefully) explanationof how Intel's Ethernet Controllers provide SR-IOV support in an Virtualized Environment.

This is part 2 of 2 of my overview of Intel Ethernet Virtualization Technologies - recommend you view part 1 first.

GPUs with SR-IOV?

[Kutta32]

@meandi02 I was thinking about that myself recently. However SR-IOV is for a PCIe Endpoint (Ethernet, Video, RAID, etc.). GPU isn't really a PCIe endpoint (doesn't move data in and out of the system).

So not sure if GPU would be a good fit for SR-IOV.

When using pci direct pass-through, a VM can directly configure the device to do DMA and when data comes in, the device directly puts the data into guest's memory. With the one time configuration of VMM and EPT, this removes the need for CPU from the process of moving data to guest. So in slide 27, I don't see why the summary of Intel SR-IOV is this.

very much informative.
