Thanks for your kind words! We're all virtualization users ourselves so I definitely get what you mean - we started this project because we wanted to help people to get access to the magic at home using the hardware they already have!

Ya, that's exactly correct. :)

Hey, I'm the co-creator of LibVF.IO and the GVM project. I'd love to hear what you think about our latest release where we added support for GVM components in LibVF.IO. Side note: We also added in support for Libvirt by allowing u

Ya! It's in the install guide. Most package updates don't disrupt anything. Depending on the vendor driver you use (Intel i915, AMD GPU-IOV Module, Nvidia) kernel updates should be okay if we use DKMS. GPU-IOV Module works okay wi

Nearest I can tell the guy earlier thought what mdevctl is (echo uuid >> /sys/mdev_bus/$pci-device/available-types/) is the same as what we are doing. That couldn't be further from the truth. I tried expl

We've got it down to running a script twice and rebooting once then installing your VM. I'm hoping we can simplify a bit further with time. :)

> GVM isn't built in a way which is usable by any other project. That's ok, but it does nothing to explain the design decision. It is. You configure a YAML/JSON file to define the mdev types that are presented by the vendo

I am also looking forward to when it's mainlined. Having said that until a short time ago everything going on with i915 SR-IOV was a secret (nobody on the i915 mailing list would talk about it, there was no open source) so I'd say

This works on most Nvidia consumer cards (not just datacenter cards): https://openmdev.io/index.php/GPU_Support I think we have decent coverage of device support: https://store.steampowered.com/hwsurvey

Ya, that works. :)

Again as in your other comment GVM does not actually have anything to do with LibVF.IO right now. They don't even work together. GVM/Mdev-GPU is actually a free software component that virtualizes GPUs, not a wrapper for QEMU&#x2F

I believe we're expecting units in a few weeks.

On AMD, yes (sadly). On everything else, no.

Ya, you can definitely do that. Here's our current install documentation: https://arccompute.com/blog/libvfio-commodity-gpu-multiplexi... This will be updated against our GVM/mdev-gpu sources shortly but our

Intel's Xe embedded SKUs are supported: https://openmdev.io/index.php/GPU_Support We did some things to enable GPU virtualization on older driver revisions for most Nvidia consumer GPUs and some AMD GPUs as well.

Hey, OP here. Sorry I didn't get to this sooner as I posted this just before falling asleep. This comment basically hits the nail on the head in most areas. I am happy to say though that Intel now uses SR-IOV instead of GVT-g (deprecat

Hey! I'm happy to report Intel's new SR-IOV driver for 11th generation Xe GPUs is now public! Checkout their commit for that over here: https://github.com/intel/linux-intel-lts/commit/41ef979f0894...

It's funny to hear Apple talking about how mandatory Webkit is a feature when iOS 1 ran Safari as root.

I'm a contributor to OpenMdev. This wiki is meant to document how VFIO and SR-IOV functions work (including on consumer devices). Here are a few of the good articles on the site (I think): https://openmdev.io/index.php&
