I understand that much. Perhaps I didn't express myself clearly. It's just that in version 7.3.0, a new feature was added allowing you to change the number of VFs under "PCI Devices and IOMMU Groups" as well. Now there are two places where I can modify these settings:

Settings --> Intel Graphics SR-IOV

Do you see what I mean now?

After updating to 7.3.0, I found that the virtual graphics card generated by SR IoV can be used for Windows 11, but cannot be used for FNOS. Now I have rolled back to 7.2.4

will this work now on 7.3 with i5 14500 ?



if i passtrough it to my windows guest, i can install the intel display driver, devicemanager shows all ok, but parsec still uses software renderer and can run furmark etc.

edit:

ok, worked, but my whole igpu crashs after VM shutdown .. need to do :

echo 1 > /sys/bus/pci/rescan

in unraid shell + add VFs back (no restart nessesary , worked again after)

but after each VM reboot / shutdown, the igpu crashs and i need rescan and readd the VFs, any solution for this?

Hi, kinda noob and everything is working but I just wanted to ask about the version. I installed the plugin from unraid CA and the version is 2023.11.22 and that shows as up-to-date, but the github itself has versions newer than that. How come this is the case?

Hi, I'm not sure if this is the right place but I'm wondering if someone can either explain or direct me to a page that explains how to get SR-IOV working with the Intel 285k iGPU to pass a VF through to a VM.

I've looked around but the information is conflicting, am I supposed to use the Xe driver or can I still use i915? Am I still supposed to use this plugin as well? Is it even possible right now (the posts seemed to imply the kernel would support it early 2026 but haven't heard anything since). Any help with the latest info on this would be greatly appreciated.

I have never been successful at getting a linux guest to successfully pass through a VF.

I am trying again, because I really need access to the i915 graphics to run frigate.

using cachyos (arch) as a guest... and tried a few things to get it going... but errors out like this:

If you've managed to overcome something similar I would appreciate some steps to try. googling has not really helped me.

I am running latest unraid... with sriov plugin installed and working. Win11 VM is able to work with this... but linux guests must have a secret sauce I am not aware of....

@bucky2780 the sr-iov dkms module must be installed on Unraid and inside the guest. In addition all the apps in the guest(think the desktop environment, Plex, jellyfin, frigate) must run as a user with permission to access the gpu. This is not always the case and you must always check that the dkms module is installed and running without errors on the host (Unraid) and the guest and the relevant users have permission to use the gpu in the guest. It took me months to figure out those two things for Linux guests, windows just works out the box

ok interesting... I don't mind spending months trying to get this to work....

but on a recent cachyos vm install... here is what I get when I add a vf as graphics device....

I did install dkms on the guest... though I'm surprised that would be needed.

mystery abounds...
