Looking for qemu guest gpu hardware recomendation

[thorsummoner]

<if a similar thread exists, the built in search failed me>

Heya, I’ve been really excited for, and wanting to do the IOMMU/SRIOV(?) hoop jumps with QEMU/KVM on a debian (or derivative) linux –

To-date, I’ve never been sure if the hoop jumping failed an an account of hardware, or software –

Since the hardware and attempts made are too varied to discuss, nor really significant to my interests in knowing the hardware isn’t at fault, what I come here looking for a somebody who has been running Redhat KVM with QEMU backend, to say “this specific motherboard, gpu, and generation of hardware defiantly can work because I run it myself”

Maybe that person doesn’t exist yet, and my best bet is to take less-of-a-gamble on Wikipedia’s List of IOMMU-supporting hardware –

Either way, the closer the Level1Tech’s video presence comes to actually demoing/tutorializing gpu passthough from scratch, the more excited I am to commit to a build and get the parts;

If anyone does know of a working part set, I would really enjoy the confidence that at the very least I’m not starting to try cool things on hardware too old or too cheap to even consider enabling the cool

Thanks for your kindness and politeness L1T <3

intel HEDT is the best if you’re looking for a worry/hassle free experience. All nvidia gpus have the same bug, some AMD cards are bug free, while others just plain refuse to reset when you shut down the VM. All the bugs have a workaround though.

As for working part sets, there’s this:

if you have any other pressing questions about VFIO, there’s the wiki:

The VFIO and Passthrough One Stop Shop

Seems like we get a new thread almost every day with people having the same problems setting up a passthrough VM. The Purpose of this Wiki is to be a resource and reference for people who want to set up a VFIO system, or have one already and need advice or Tutorials for the various facets of that system. I will be adding categories like ‘input’ ‘screens’ etc – these can be expanded as necessary. Basic Setup Guides on setting up a passthrough VM The archwiki guide: https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF This is the gold standard in passthrough setup tutorials. It is by and large the most complete, best maintained, and most accurate reference available. The vast majority of the information is completely distro agnostic, with the single caveat being mkinipcio being distro specific (dracut on fedora etc) This should always be your first reference. Explainers/Benchmarks Information on various ill documented or not-oft-explained aspects of VFIO. Benchmarks should also be put here as the effectiveness of many commonly suggested tweaks are not very well characterized. Hardware buying and quirk guide: https://passthroughpo.st/vfio-increments/ Input resources for people looking for keyboard/mouse input sharing solutions or other input-related topics. Storage Information on best practices for images, VirtIO, etc. Display/GPU VFIO Topics pertaining to your VM’s display, native or otherwise. Audio VM audio resources. Distro Specific Apparmor, distro specific software, issues, and workarounds. Tools and Projects Software that enhances the VFIO experience, or VFIO use cases outside of GPU passthrough https://looking-glass.hostfission.com/ This is a tool that allows users to take advantage of KVMFR, using 3d accelerated VMs without needing a native display
