Booting the noble image with qemu-system-riscv64 -machine virt -m 4G -smp cpus=2 -nographic \ -kernel /usr/lib/u-boot/qemu-riscv64_smode/u-boot.bin \ -netdev user,id=net0 \ -device virtio-net-device,netdev=net0 \ -drive file=noble-live-server-riscv64.iso,format=raw,if=virtio \ -drive file=disk,format=raw,if=virtio \ -device virtio-rng-pc ends up in the GRUB rescue console: grub> ls $root error: invalid file name `hd0,gpt2'. grub> ls ($root)/ efi/ dtb/ ubootefi.var grub> Same problem with EDK II using qemu-system-riscv64 -machine virt -m 4G -smp cpus=2 -nographic \ -drive if=pflash,format=raw,unit=0,file=/usr/share/qemu-efi- riscv64/RISCV_VIRT_CODE.fd,readonly=on \ -drive if=pflash,format=raw,unit=1,file=RISCV_VIRT_VARS.fd \ -netdev user,id=net0 \ -device virtio-net-device,netdev=net0 \ -drive file=disk,format=raw,if=virtio \ -device virtio-blk,drive=ISO,bootindex=1 \ -drive file=noble-live-server-riscv64.iso,if=none,id=ISO \ -device virtio-rng-pci - I don't experience any problem with the Plucky image. - When I emulate a CD-ROM it works qemu-system-riscv64 -machine virt -m 4G -smp cpus=2 -nographic \ -drive if=pflash,format=raw,unit=0,file=/usr/share/qemu-efi- riscv64/RISCV_VIRT_CODE.fd,readonly=on \ -drive if=pflash,format=raw,unit=1,file=RISCV_VIRT_VARS.fd \ -netdev user,id=net0 \ -device virtio-net-device,netdev=net0 \ -drive file=disk,format=raw,if=virtio \ -device driver=virtio-scsi-pci,id=scsi0 \ -drive if=none,file=noble-live-server- riscv64.iso,format=raw,readonly=on,id=CDROM \ -device driver=scsi-cd,bus=scsi0.0,drive=CDROM,bootindex=1 \ -device virtio-rng-pci So it seems our current Noble ISO is not properly set up to be used a disk image.
