I use libguestfs to extract files from the guest SD card image. $ xz -d Įxtracting the guest boot partition contents I’m using the unofficial preview images described on the Debian wiki. libguestfs (on Debian and Ubuntu, install the libguestfs-tools package).You’ll need the following things on your host system: The QEMU model is missing models of some devices, and others are guesswork due to a lack of documentation of the hardware so although the kernel I tested here will boot, it’s quite possible that other kernels may fail.If you want to boot a 32-bit kernel you should use the “raspi2” board model. ![]() Our raspi3 model will only boot AArch64 (64-bit) kernels.This means that there is no networking support, because on the raspi devices the ethernet hangs off the USB controller. We don’t have an emulation of the BCM2835 USB controller.You need to manually extract the kernel, initrd and device tree blob from the SD image first. We don’t emulate the boot rom, so QEMU will not automatically boot from an SD card image.Things to know before you startīefore I start, some warnings about the current state of the QEMU emulation of this board: The model is sufficient to boot a Debian image, so I wanted to write up how to do that. For the QEMU 2.12 release we added support for a model of the Raspberry Pi 3 board (thanks to everybody involved in developing and upstreaming that code). ![]()
