After some searching works, however, I barely find any reading material or tutorial about the details of using QEMU in kernel development, especially the driver development.

You can use the following command
-append "root=/dev/sda console=ttyS0"
You can run this command from the root directory of whichever kernel
tree you are hacking on. I can't remember how I built/got the QEMU
image though. There are tutorials online about creating a QEMU image.
Hope this helps,
