vl.c is the main() function for the qemu-system-* family of programs
(the "system emulators").  You could start exploring the source code
from there.  That's what I did when I first started hacking on QEMU.

Be prepared to read code.  QEMU isn't an educational codebase and the
code reflects the requirements of many contributors over the years.
Most of their requirements may not be relevant to you.  You will learn
to skip the stuff that doesn't affect you and to see the big picture.

If you have a specific area you are interested in, let us know and we
can tell you which source files are involved.
