I think this is being caused by an incorrect machine instruction
somewhere. From my debugging here, I see that when booting the Sparc64
image, gdb gets stuck in a loop somewhere in cpu_exec() in
vl.c:main_loop() and so never makes it down to vl.c:main_loop_wait() to
process the VNC events.
Does anyone have any HOWTOs/clues/debugging resources for qemu to help
when trying to troubleshoot these kinds of low-level problems?
ATB,
Mark.
