| 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. |
