I get Driver Error 43 in Windows 10 guest trying to use VT-D or SR-IOV in both KVM, ProxMox and VMware ESXi.
Same goes for Wifi PCI-E (VT-D only). Error 43 no matter what.
I have newest BIOS 058n and its been the same with 57 too. Also BIOS mentions a lot of LED and LED colors but no matter what I change the colors are always the same?!?
Thank you for posting on the Intel️® communities. To investigate this, please share with us the Intel® System Support Utility (Intel® SSU) results:
- Download the Intel SSU https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows-
- Open the application and select "Everything" click on "Scan" to see the system and device information. By default, Intel® SSU will take you to the "Summary View".
- Click on the menu where it says "Summary" to change to "Detailed View".
- To save your scan, click on "Next", then "Save".

We are aware of this issue and our current position is that we consider that ESXi* is an Operating System designed for Server Systems and not for Clients, when I run ESXi 7.0 Update 2, I see the error 43 that you describe but we don't have any solution or workaround for this issue at this point. Please refer back to Supported Operating Systems for Intel® NUC Products: https://www.intel.com/content/www/us/en/support/articles/000005628/intel-nuc.html
As a side note: We tried to replicate this issue by testing "VMware-player-16.1.2-17966106" in combination with our NUC and we dont see error code 43 in the device manager.
That's not how it works. As previously advised the NUC is supposed to support VT-D and allow the passthrough of the GPU into guest systems. You can't say that it supports VT-D but not be able to take advantage of it in any guest operating systems.
This is an incredible step back for the NUC range. If you could please confirm that the marketing for the device is wrong then I will be able to return the device to where I purchased it from and grab something that does what it says it will do on the box.
Can you please escalate this issue? It's pretty bad for the marketing material for a device to say it does something, and then people buy it thinking it will do just that, and have it not work at all.
Actuallly I can find no way of using either VT-D or SR-IOV with vmplayer since it does not support adding pci-devices that way. What about KVM, Proxmox or Hyper-V?
Hyper-V runs on Windows and supports VT-D and SR-IOV so I could test it there, but I guess it will not work there either since so many ppl already tried. What software did you use during initial product develoment to test SR-IOV and VT-D on this platform?
Any news on this? Having the same issue on Rocket Lake S (i5-11600), error 43 all the time when doing passthrough via ESXi 7.0 U2 (and now even U3).
iGPU passthrough was perferctly possible with my previous E3-1225v5.
I dont see any SR-IOV option in BIOS and when I run the following command: "get-netadaptersriov" I dont get any result either so I would say that SR-IOV is not supported.
On the other hand VT-D is supported, see image attached and you may also refer to the following article: Unable To Set Single-Root I/O Virtualization (SR-IOV) and Virtual... (intel.com)
But I read in specs it is supported for the gaphics because GVT-G was withdrawn on 11th gen they added SR-IOV
And here is a thread about it.
Ok so it all boils down to using VT-D then. Which is supported in BIOS and on papers but the drivers in the guest does not load on either Hyper-V, KVM or Vmware ESXi. Seems to be something in the driver then maybe?
We are aware of this issue but we don't have a fix for now and I don't know if there will be a fix. ESXi* is an Operating System designed for Server Systems and not for Clients and therefore not validated for this platform.

@Ronny_G_Intel Are you kidding? the datasheet of the Tiger Lake and Rocket Lake CPU's are strictly advertising a VT-d functionality which isn't working. This has nothing to to with unsupported OS on the platform, Intel is just not delivering what they promise here.
Maybe you should reconsider your statement as it's a shame to not deliver features which are promised and nothing less.
Refer to my previous post --> 10-12-2021 10:10 AM. VT-D is supported, I even took a screenshot of the BIOS in which this feature can be enabled or disabled. I am talking about SR-IOV which is not supported in Tiger Canyon.
And on top of that, the issue I was referring to is Windows 10 - Device Manager reports an issue with Iris GPU "Windows has stopped this device because it has reported problems. (Code 43) when running on top of ESXi* (iGFX passthrough).
