The global hack for creating SCSI devices has recently been removed, but this apparently broke SCSI devices on some boards that were not ready for this change yet. For the pica61 machine you now get: $ mips64-softmmu/qemu-system-mips64 -M pica61 -cdrom x.iso qemu-system-mips64: -cdrom x.iso: machine type does not support if=scsi,bus=0,unit=2 Fix it by calling scsi_bus_legacy_handle_cmdline() after creating the corresponding SCSI controller.
