Hello all,
I just bought the CWWK N100 mini pc to run as a low powered server: https://cwwk.net/collections/frontp...oft-router-proxmox-ddr5-4800mhz-4xi226-v-2-5g
I've followed this tutorial to setup GPU passthrough:
https://www.servethehome.com/how-to-pass-through-pcie-nics-with-proxmox-ve-on-intel-and-amd/
It took me quite a bit to get everything to work as apparently my system is making use of systemd boot rather then GRUB.
Anyway, I've setup my VM as follows:
When I start this VM the screen of the HOST turns black (I think this is as expected as the VM is now taking over).
However no output from the VM is displayed.
I did try to set the Display to "SPICE" and then boot the VM, this resulted in noVNC working again but in Device Manager it shows that the Intel N100 has error 43.
Things I've already tried which didn't work:
All my configs:
VM Config:
SYSTEMD boot config:
Modules config:
dmesg output:

Things I've already tried which didn't work:
- Tick the PCI-Express box
- Ensure IOMMU is enabled (it shows in DMESG + I can select the Raw Device)
- Try to unload the i935 driver by adding it to the blacklist.
- Try to unload the i935 driver by adding it to the systemd boot file.
