I have made it using cortex-a9 which is suitable for raspberry pi 2 (I have followed actually this tutorial) so the command for that should be: $qemu-system-arm -kernel vexpress_04_zImage -append "root=/dev/mmcblk0p2 rw" -m1G -cpu cortex-a9 -M vexpress-a9 -sd pi-snappy.img Which is I think should be fine nowadays
