Should be something like: qemu-system-sparc64 \ -m 4096 \ -device virtio-blk-pci,bus=pciB,drive=hd \ -drive file=/home/brauner/.local/share/qemu/sparc64.img,format=raw,if=none,id=hd,bootindex=0 \ -net nic \ -net user \ -nographic Note the removal of the legacy -boot argument and the addition of "bootindex=0" to the -drive argument.
