I followed the instructions from the document located at https://wiki.linaro.org/KenWerner/Sandbox/AndroidQEMU

But I didn't do patch mentioned in the document, because the latest qemu source code was different from the one referenced in DOC.

Then I followed the other steps:

I used Vexpress binary from http://releases.linaro.org/13.07/android/vexpress

At last, after I entered the qemu command like this:

qemu-system-arm -M vexpress-a9 -m 1024 -smp 1 -snapshot -serial stdio -no-reboot -kernel vmlinuz -initrd initrd.gz -drive file=../vexpress.img,if=sd,cache=writeback --append "console=tty0 console=ttyAMA0,38400n8 rootwait ro init=/init androidboot.console=ttyAMA0"

There was an booting error:

pulseaudio: set_sink_input_volume() failed

pulseaudio: Reason: Invalid argument

pulseaudio: set_sink_input_mute() failed

pulseaudio: Reason: Invalid argument
