I added the section in the xml file of the VM win10 and I got the following error:
Error starting domain: unsupported configuration: host doesn't support passthrough of host PCI devices
when trying to start the VM I got this error
Traceback (most recent call last):

I posted in this post because when I do the virt-host-validate command I got the same error the one mentioned earlier
Ubuntu 22 No ACPI DMAR table found, IOMMU either disabled in BIOS or not supported by this hardware platform on nested VM
VT-D is enabled as we can see in the mesag
$ sudo dmesg | grep -e DMAR -e IOMMU

I specified the PCI id in the conf as well. the hardware is old for sure but I was really hopping to use pass through feature to connect the Video adapter.
Is there any chance to get that working one day or should I look for a new hardware?
Please check the screenshots as well
