That's correct, libvirt knows those controllers only have
a single slot and will prevent you from adding more than
one device to them. So no change needed there.
IIUC Lukáš is using QEMU directly in (some parts of)
Avocado, so I imagine emitting an error rather than
silently accepting an invalid configuration would save
him some debugging time :) But he knows not to do that
now, so I guess low priority sounds about right.
Thanks for clarifying!
