Problems with PCI Passthrough in TrueNas Scale

[Gustavo_4523]

Hi, i'm new to TrueNas and im having issues setting up a VM with GPU passthrough. Having look multiples fóruns trying to find any solution but made little progress. Here's what I have tried and done:

Isoleted GPU device:

Found and mapping IOMMU groups:

List of PCI devices:

Add PCI passthrough in VM:

And get get this error following this:

VD-T is on in the bios, and integrated GPU is enable, I get the following error after trying whitout vd-t up:

"[EFAULT] VM will not start as PCI Device: pci_0000_00_01_1, PCI Device: pci_0000_02_00_0, PCI Device: pci_0000_02_00_1, PCI Device: pci_0000_00_01_0, PCI Device: pci_0000_01_00_0, PCI Device: pci_0000_01_00_1 device(s) are not available."

This is happened when I passed all group 1 IOMMU to the VM and my system just crashed after get up, só I disable VT-d and remove all pci passthroughts, thus getting this error described above, after this I am kinda lost about what to do tho fix this.

System:
Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz
64 GB Ram
OS Version:TrueNAS-SCALE-22.12.2
Product:Z170X-Gaming 7

Anymore information about system or the issue itself feel free to ask.
If anyone has crossed with someone like this feel free to help
Thanks in advance for ever person who takes the time to read all the way until here, have a great day.

I'm a little confused on why you expect PCIe passthru to work if you disabled it.

I disabled just to boot the system and restart, its up now.

I disable VD-T because the system was crashing after start, so I disable it, remove PCI from the VM and re-enable it in bios, add a pci again and get this error described in the image above.

Sorry if i wasn't clear in the first post.
