What does the following command give you?
for d in $(ls /sys/kernel/iommu_groups/15/devices/); do lspci
-nnvs "$d"; done
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.
That is nothing I have done explicitly as far as I am aware, from my
perspective Fedora has done that itself.
My understanding is that it's a hardware thing, probably related to
how the motherboard is built. In some cases, you can move devices to
another slot, but of course that can't happen in this situation.
I believe the grouping is done by Fedora and if it wanted to it could
add those devices to different groups, so what are the rules around how
Fedora groups devices together like that?
As you have said the two ethernet controllers on my motherboard have
been grouped together with the wifi device, and, the wifi device and one
of the ethernet controllers are not actually being used so why are they
grouped with active devices?
