I've put the output from that command in the attachment. In that output
the device indicated as a Mediatek device is the one I tried to add to
the VM which is producing the error.
That doesn't look promising. You have a lot of things in that iommu
group including both of your ethernet devices.
Without that device the VM boots quite happily, and from what George
was showing, the second version of the 6.18 kernel doesn't appear to
have support for the chipset that I read was supposed to be being
provided in the 6.18 kernel. It may be too early in the kernel release.
I've checked the host system and the device that I think is the wifi
device, as shown by INXI has bus-ID 08:00.0 which is the bus address
shown in the message above, so I believe I have selected the correct
device. The only thing I can think of is QEMU is expecting the host
to have provided a driver for that device which in the current
kernels doesn't exist, and, if that is the case that defeats the
purpose of the test I'm trying to do which is check if the 6.18
kernel is going to provide a driver. Am I looking at things
incorrectly?
The driver might not be available yet:

I've looked at that thread and that person is using a later version of
the kernel to what I see available and as the thread says the driver
isn't available yet. What I also found interesting is the ID of Steve's
device is 14c3:7927, whereas my device ID is 14c3:6639, so maybe my
device is not using the MT7927 chipset but an MT6639 chipset which also
seems to be not supported in the current kernels?
I don't see any indication that either of those are close to being
supported.
