There are still a number of missing pieces (including display and USB) which I hope to submit soon, but you should be able to boot Linux with a serial console. Brief instructions are at the end of this page: https://github.com/0xabu/qemu/wiki BTW, instead of -hda you need to pass -sd for the image file.
