Intel Core Ultra iGPU passthrough
-
Hi everybody,
First of all I would like to thank all the contributors for the hard effort put into building and maintaining this project and for the vast amount of support that this forum has been giving!
Specs:
DELL Tower
CPU: Intel Core Ultra 5 235
XCP-ng 8.3I have been trying to passthrough the iGPU to a VM running Debian 13 but keep getting errors.
I have successfully passed older intel iGPUs and have always worked perfectly.PCI pass through enabled:
I don't know if this is normal but if I attach the GPU using xcp-ng center it shows up in XOA:
But not as a pci device:
Regardless, I have also attached as pci:
Halted VM:
Running VM:
Upon boot console gets filled:

...lspci detects the gpu, but it's not usable.
Also tried changing to XE drivers instead of i915 and didn't help.
Because I don't know enough to diagnose this, I tried asking AI which prompted me to perform "xen-pciback.hide" for the Intel Management Engine (ME) and still didn't help.
Also tried with Ubuntu 25.10.Has anyone been able to pass through a similar iGPU?
Sorry for the image spamming.
Thank you.
