[RFC] nvme errors on QEMU

[Heinrich Schuchardt]

I am calling qemu-x86_64_defconfig with

qemu-system-x86_64 -machine pc-i440fx-2.5 -m 1G -smp cores=2 \
         -bios u-boot.rom -nographic -gdb tcp::1234 \
         -drive file=../sandbox.img,if=none,format=raw,id=nvme1 \
         -device nvme,drive=nvme1,serial="S3EWNX0J123456K" \
         -netdev user,id=eth0,tftp=tftp -device e1000,netdev=eth0 \
         -device virtio-rng-pci

nvme info displays a lot of errors:

Why does 'nvme scan' create 255 nvme-blk devices too many?

Best regards
