+**Note**
+
+- For the `virtio-ivshmem-block` you can find it in target system at `/usr/bin/`, if not then copy it from here `build/tmp/work-shared/qemux86-64/kernel-source/tools/virtio/virtio-ivshmem-block`.
+
+- For the `disk.img`, It needs to be a raw image. But its size matters as that defines the virtual disk size, but you may even leave it empty and only partition or format it from the front-end guest.
+
+e.g:
+
+```sh
+$ dd if=/dev/zero of=disk.img bs=1M count=1024
+$ mkfs.ext4 disk.img
+```
+this can be accessed via `/dev/vda` in the frontend.
