I have installed a raspberry PI OS 64bit running on a RPI4 I'm trying to figure out how to configure qemu-system-arm using the precompiled images.
The provided precompiled images should have kernel and rootfs combined, but how i should set the kernel and the drive images in qemu from them ?

Images are full disk images. Rootfs and kernel images are also availables in downloads directory.
But using OpenMPTCProuter on RPI4 VM is really not a good idea: a RPI4 doesn't have a so good CPU...

About CPU i know i won't get the best performances but i would like to try it.
I'm a noob on virtualization stuff but i'm still learning.
However i can't see separated rootfs and kernel images on downloads directory: I can only see the sysupgrade and factory images in their ext4 and squashfs versions here.
I should use the sysupgrade image when i already have an OpenMPTCProuter installation,
and i should use the factory image to mount it on the sd card ( on non virtualized scenario) from what i understanded. Am i missing something ?

So i should set the ext4-factory image as drive ( as qemu parameter -drive file=openmptcprouter-v0.58.5-r0+16336-b36068d35d-bcm27xx-bcm2709-rpi-2-ext4-factory.img,format=raw ) but what i should use as kernel parameter ( -kernel $IMAGE -append "root=/dev/sda2" ) ?

this is the script i would use to run the qemu vm:

#!/bin/sh

MACHINE=raspi2
RAM=512
KERNEL=??
DRIVE=openmptcprouter-v0.58.5-r0+16336-b36068d35d-bcm27xx-bcm2709-rpi-2-ext4-factory.img
EMU32=qemu-system-arm

$EMU32 -M $MACHINE -m $RAM \
-kernel $KERNEL -append "root=/dev/sda2" \
-drive file=$DRIVE,format=raw

i followed the openwrt guide on arm but as the guide shows i expected to find a zImage in the downloads directory to use as kernel image

True rootfs is only generated for x86_64 and can be used for Docker.
In you case you should use full image as it's a complete virtualisation. kernel is already in the raw image, you don't need to specify an external kernel.
So should be something like qemu-system-arm -m 1024 -machine type=raspi3 -drive format=raw,file=openmptcprouter-v0.58.5-r0+16336-b36068d35d-bcm27xx-bcm2709-rpi-2-ext4-factory.img or something like that.

Setting the drive as the combined image doesn't boot on qemu.
here for openwrt says that the combined image as initramfs should works if set as kernel. I tried using the combined image of OpenMPTCProuter but again doesn't boot.
So i though to use the openwrt armvirt kernel and it worked:


EMU32=/home/pi/qemu-6.0.0/build/qemu-system-arm #emu-system-arm
EMU64=/home/pi/qemu-6.0.0/build/qemu-system-aarch64 #qemu-system-aarch64
EMU=$EMU32
MACHINE=virt
RAM=512m
KERNEL=./omr32/openwrt-19.07.7-armvirt-32-zImage
DRIVE=./omr32/openmptcprouter-rpi-2-ext4-factory.img

$EMU  \
  -M $MACHINE \
  -m $RAM \
  -kernel $KERNEL \
  -append "root=/dev/vda2 panic=1" \
  -drive "file=${DRIVE},if=none,index=0,media=disk,format=raw,id=disk0" \
  -device "virtio-blk-pci,drive=disk0,disable-modern=on,disable-legacy=off" \
  -device virtio-net-pci \
  -netdev user,id=net1,hostfwd=tcp::2222-:22 \
  -device virtio-net-pci,netdev=net1 \
  -no-reboot -nographic

but i don't think si the right way to do that.

( i resized always the combined image because qemu errors:

FILE=openmptcprouter-v0.58.5-r0+16336-b36068d35d-bcm27xx-bcm2709-rpi-2-ext4-factory
TOFILE=openmptcprouter-rpi-2-ext4-factory

$HOME/qemu-6.0.0/build/qemu-img convert -f raw -O raw "$FILE.img" "$TOFILE.img"
$HOME/qemu-6.0.0/build/qemu-img resize -f raw "$TOFILE.img" 1G

)
So i tried this qemu-rpi-kernel and worked for raspianOS.
I tried the same extracting kernel.img and dtb ( as says also here ) and setting the drive as combined image but doesn't boot.

i tried all this with both arm and aarch64 qemu-systems in version 3.10 and 6.0.0

However using the openwrt kernel for armvirt i think a lot of things are missing, for example i have no ethernet vitual interface if i use ifconfig. This is the output:

You can't use OpenWrt kernel as at least MPTCP patch is missing.

I supposed that, but it's weird that even using the openmptcprouter's kernel inside the combined image doesn't boot.
I got and edited the script from here using the openmptcprouter's kernel, rootfs and dtb

i got some "results" ... upgrading qemu to 6.2.0 and running the following script with qemu, something changed.
(before running this i run only the qemu-img resize code)

$HOME/qemu-6.2.0/build/qemu-system-aarch64 \

	-cpu cortex-a53 \

	-netdev type=user,id=net,hostfwd=tcp::2222-:22 \
	-device usb-net,netdev=net \

Qemu seems to boot but stop the emulation after running /sbin/init. Here the log:

i forgot to say that i tested this not using native emulation, because i want to test it as vm before using it on rpi4.
the vm host is not a rpi4 but a x86_64 machine, but should't be a problem since i'm emulating rpi

After some tests i find out that it's an OpenWrt issue.
for some reason i think the built OpenWrt image isn't qemu compatible ( maybe because there are network issues about virtio-net-pci).
The only way that i tested and works is setting the machine type as virt and set the kernel & fsroot in a drive both of a compiled OpenMPTCRouter build for armvirt platform.
The build process is explained here; Just checkout to a version and set the same version to OMR_FEED_SRC. in my case i set OMR_TARGET="armvirt" OMR_FEED_SRC=" v0.58.5".
In make menuconfig phase, i set the arm virt target and cortex-a53 architecture.
After the build the images are in the armvirt/source/bin/ folder.
In my case i run the following code:

EMU32=qemu-system-arm
EMU64=qemu-system-aarch64
EMU=$EMU64
MACHINE=virt
CPU=cortex-a53 # 64bit
CORES=2
RAM=1G
DRIVE="openmptcprouter-v0.58.5-f557cb00-r0+16336-b36068d35d-armvirt-64-rootfs-ext4.img"
KERNEL="openmptcprouter-v0.58.5-f557cb00-r0+16336-b36068d35d-armvirt-64-Image"

$EMU \
	-M virt \
	-cpu $CPU \
	-smp $CORES \
	-m $RAM \
	-no-reboot -nographic \
	-drive file=$DRIVE,format=raw,if=virtio \
	-kernel $KERNEL \
	-append "earlyprintk loglevel=8 console=ttyAMA0 root=/dev/vda rootfstype=ext4 rootwait" \
	-device virtio-net-pci,netdev=net \
	-netdev type=user,id=net,hostfwd=tcp::2222-:22 \
#	-netdev type=bridge,br=virbr0,helper=/usr/lib/qemu/qemu-bridge-helper,id=net  # for this see https://wiki.qemu.org/Features/HelperNetworking
#	-serial stdio

But this will emulate the virt machine, so if you want run qemu KVM on RPI, the CPU var should be set as "host". (i didn't test this yet, but i will try soon)
