Dear all,
I am trying to debug QEMU via GDB.


I configured and compiled QEMU with debugging flags, i.e.,
# CFLAGS="-g3 -O0" ./configure --disable-gfx-check


and run gdb:


# gdb ./i386-linux-user/qemu-i386


(gdb) break main
(gdb) run

Starting program: /home/test/femu/i386-linux-user/qemu-i386
Failed to read a valid object file image from memory.
Warning:
Cannot insert breakpoint 1.
Error accessing memory address 0x2f7df: Input/output error.


Is there any extra flag to be specified with the GDB for QEMU debugging? 
I am wondering if the QEMU virtual machine creates any problem to the 
GDB virtual machine.


Thanks.


G.
