Error (no boot device found) running qemu image

Hi there,

I've followed the instructions on https://wiki.linaro.org/Source/ImageInstallation to generate a qemu image using linaro-media-create and although the image was generated fine, I got the following error when trying to run it:

qemu: hardware error: no boot device found CPU #0: R00=00000000 R01=00000000 R02=00000000 R03=00000000 R04=00000000 R05=00000000 R06=00000000 R07=00000000 R08=00000000 R09=00000000 R10=00000000 R11=00000000 R12=00000000 R13=00000000 R14=00000000 R15=400140a4 PSR=400001d3 -Z-- A svc32 Aborted

That was using today's daily headless tarball, btw.

Any ideas what's wrong?
