qemu on Raspberry Pi Arch Linux latest sd image
In case archlinux-hf-2013-07-22.imgHere there 3 partion are made.you can check by using
fdisk -l archlinux-hf-2013-07-22.img
rootfs is in sd5 i.e 5th partion.
So pass this parameter "root=/dev/sda5 panic=1" , it will boot perfectly.
In 2013-05-25-wheezy-raspbian.imgYou can use same kernel for both image.
Here you have to comment ld.so.preload which will load some shared-library,which will unable login. so kernel panic.
Note:-"root=/dev/sda2 panic=1" pass this parameter only.
You can comment it by doing below.
sudo kpartx -av 2013-05-25-wheezy-raspbian.img
mkdir tmp
sudo mount /dev/mapper/loop0p2 tmp/
cd tmp/etc
sudo vi ld.so.preload/usr/lib/arm-linux-gnueabihf/libcofi_rpi.socomment
#/usr/lib/arm-linux-gnueabihf/libcofi_rpi.so
umount /dev/mapper/loop0p2kpartx -d 2013-05-25-wheezy-raspbian.img
Then run qemu
qemu-system-arm -kernel kernel-qemu -cpu arm1176 -m 256 -M versatilepb -no-reboot -serial stdio -append "root=/dev/sda2 panic=1" -hda 2013-05-25-wheezy-raspbian.img
this will perfectly boot without any trouble
