When -nographic is specified, no graphical window is created.  The only 
way to see the graphics window is using the VNC option.

Furthermore, when -nographic is specified, I think "-monitor" defaults 
to "serial", meaning the actual serial output is overridden by the qemu 
monitor.  To change this, look at "-monitor" and direct it somewhere 
else (such as to a TCP stream).

Does this help?
