i tried to solve my problem for 5 days but i couldnt.
my host machine is windows 10 x64.
i want to debug linux ubuntu 16.0.4 lts i386. i created two virtual machine with virtual box and installed both ubuntu i386 16.0.4 lts version. one is to be debugged and other is for remote debugger. i compiled same kernel of ubuntu 16.0.4 lts i386 with debug info and other settings like kgdb settings.
i used kgdb + virtualbox tecnique for debugging.i also used serial communication for kgdb.
my problem is that if i put breakpoint anywhere in kernel from remote gdb and type c for continue , ubuntu machine doesnt stop at breakpoint.

above two pictures are my problem.
if i disable "Enable Vt-x/AMD-V option" for ubuntu_debugged virtual machine, then kernel gives kernel panic .
picture of kernel panic: i66.tinypic.com/20rk1sw.png
by the way, if i put breakpoint anywhere in kernel, kernel gives kernel panic. it's not related to start_kernel.
thanks in advance.
