This guilde helps you booting your newly installed debian image
This is a bit complex since we need the kernel and initrd that was installed during the installation. So we first need to loop-mount the image (or mount usb sd-card) and grab the kernel and initrd.
First find the start block of the root partition in the image.
$ /sbin/sfdisk -l -uS debian.img Disk debian.img: cannot get geometry Disk debian.img: 248 cylinders, 255 heads, 63 sectors/track Warning: extended partition does not start at a cylinder boundary. DOS and Linux will interpret the contents differently. Units = sectors of 512 bytes, counting from 0 Device Boot Start End #sectors Id System debian.img1 * 2048 3727359 3725312 83 Linux debian.img2 3729406 3999743 270338 5 Extended debian.img3 0 - 0 0 Empty debian.img4 0 - 0 0 Empty debian.img5 3729408 3999743 270336 82 Linux swap / Solaris
Offsets are given in sector size of 512 byte so multiply the start sector of the root partition (2048) with sector-size (512) to get the offset (1048576) in the image that points to the partition. Loop mount it (as root).
$ mkdir img # mount -o loop,offset=1048576 debian.img img
df should show you a line of your newly mounted disk on the img file. Copy the kernel and initrd files out from the image and unmount it.
$ cp img/boot/vmlinuz . $ cp img/boot/initrd.img . # umount img
root=/dev/sda1 which points to the root partition and start qemu with copied kernel.
./qemu-system-arm -M versatilepb -kernel vmlinuz -initrd initrd.img -append "root=/dev/sda1" -hda debian.img
This should give you login prompt after boot.
