I recently ran into an issue after enabling ESXi passthrough of the new Intel Iris Xe Integrated GPU (iGPU), which is available with the latest Intel 11th Gen Pro (Tiger Canyon) NUC and SimplyNUC Topaz. After installing the latest Intel Graphics Driver and rebooting the Microsoft Windows 10 (20H2) VM, I noticed Microsoft Device Manager would show the iGPU device with the following error message:
Windows has stopped this device because it has reported problems. (Code 43)
Unfortunately, this generic error message was not very useful in identifying the underlying issue. I was hoping the process was going to be seamless like it was for enabling passthrough of the iGPU in Intel NUC 10 (Frost Canyon) NUC, especially with the higher execution units for the 11the Gen NUC i3 (48 EU), i5 (80 EU) and i7 (96 EU).
I currently have a case open with the Intel NUC team and see if they can help investigate the underlying issue for their driver. For the time being, it looks like passthrough of the new iGPU is not fully functional when using ESXi 7.0 Update 2 and I will update this blog post if/when I have further updates to share.
