Hi experts, How can I disable the floppy controller drive when I boot a VM by qemu- system-x86_64? I did not specify any arguments about floppy, but after the qemu boots up, linux always can detect floppy drive and then modprobe the matched floppy.ko.
qemu version: v5.2 command line: qemu-system-x86_64 -device virtio-net- pci,netdev=net0,mac=52:54:00:12:34:02 -netdev tap,id=net0,ifname=tap0,script=no,downscript=no -object rng- random,filename=/dev/urandom,id=rng0 -device virtio-rng-pci,rng=rng0 -drive file=/path/to/images/qemux86-64 /qemux86-64.ext4,if=virtio,format=raw -usb -device usb-tablet -cpu core2duo -enable-kvm -m 512 -pidfile /path/to/pidfile_4167420 -m 512 -snapshot -serial mon:vc -serial null -kernel /path/to/qemux86-64 /bzImage.bin -append 'root=/dev/vda rw mem=512M ip=192.168.7.2::192.168.7.1:255.255.255.0 oprofile.timer=1 printk.time=1' As I konw BIOS can control the switch of floppy controller on a real hardware, But how can I do it on qemu? And does the qemu enable that by default? Thanks, Yanfei
