I hope these challenges are sorted at some point of time. Albert Esteve has been working on QEMU support: https://lore.kernel.org/qemu-devel/20240912145335.129447-1-aesteve@xxxxxxxxxx/ He has a viable solution. I think the remaining issue is how to best structure the memory regions. The reason for slow progress is not because it can't be done, it's probably just because this is a background task. Please discuss with Albert if QEMU support is urgent. Stefan
