| Emulation of block devices | |
| -------------------------- | |
| QEMU can emulate common block devices by adding the following parameters to | |
| the qemu-system-<arch> command line: | |
| * MMC | |
| .. code-block:: bash | |
| -device sdhci-pci,sd-spec-version=3 \ | |
| -drive if=none,file=disk.img,format=raw,id=MMC1 \ | |
| -device sd-card,drive=MMC1 | |
| * NVMe | |
| .. code-block:: bash | |
| -drive if=none,file=disk.img,format=raw,id=NVME1 \ | |
| -device nvme,drive=NVME1,serial=nvme-1 | |
| * SATA | |
| .. code-block:: bash | |
| -device ahci,id=ahci0 \ | |
| -drive if=none,file=disk.img,format=raw,id=SATA1 \ | |
| -device ide-hd,bus=ahci0.0,drive=SATA1 | |
| * USB | |
| .. code-block:: bash | |
| -device qemu-xhci \ | |
| -drive if=none,file=disk.img,format=raw,id=USB1 \ | |
| -device usb-storage,drive=USB1 | |
| * Virtio | |
| .. code-block:: bash | |
| -drive if=none,file=disk.img,format=raw,id=VIRTIO1 \ | |
| -device virtio-blk,drive=VIRTIO1 | |
| .. note:: | |
| As of v2023.07 U-Boot does not have a driver for virtio-scsi-pci. |
