r/VFIO

for my next build im wanting to play some “older” games. while looking at the intel b70 and craft computing video, stating the B70 can only be split into 7 chunks, some of those games don’t need 7GB of vram.

rimworld 1gb vram

total war 1gb vram

battletech 2gb vram

Workers & Resources: Soviet Republic 2gb vram

x4 foundations 4gb vram

2 X Sins of a Solar Empire II 4gb vram

using the fastapi-dls guide and a NVIDIA P40 can i split it into uneven chunks. would that be the best option or is there some other option i haven’t found yet?

My goal is to get VIFO and PRIME offloading working on an RTX 4070.

I'm using Fedora 43 with KDE, 3440x1440p display, 32GB RAM, and an AMD 7500F. I'm looking for an budget GPU that can smoothly handle a web browser, Spotify, Discord, and other common apps. Would something like the “Quadro K2200 4GB” be a good choice? 50-70$ would be fine.

Has anyone managed to get Rainbow Six Siege running in a VM with GPU passthrough?

I’ve seen mixed info, especially with anti-cheat.

What setup are you using and does it actually work?

Did anyone try 9950X3D2 on a VFIO setup? I mean having 3d cache on both ccd seems nice for virtualization since you only need to isolate core 8-15 when having SMT disabled.

Can I expect a performance in the VM of a 9800X3D like setup when gaming?

I am trying to install Windows 11 on a passed-through WD SN570 NVMe SSD in a Qemu/KVM VM, however Windows 11 does not show the drive in the installer. When checking the device using pnputil /enum-devices /problem, I see that the NVMe controller is detected, but has an error code 10, CM_PROB_FAILED_START.

Details:

Fedora 44 host

PCI passthrough is done using libvirt hooks, binding vfio-pci driver at boot does not work either

The NVMe is in its own IOMMU group

A Fedora 43 guest correctly detects the drive

A Windows 11 guest correctly detects a Samsung NVMe

Windows 11 detects the drive when installing on bare metal

SanDisk does not appear to provide any drivers, aside from an installer

Any help would be appreciated.
