[Qemu-devel] fail to single step qemu

[Peter Cheung]

Hi all
I created a simple debug server on qemu, it receives command from tcp, but when i try to single step qemu, it fails, it will keep running rather than stop in the next instruction. I have traced the code a little bit, for gdb, when gdb do single step, the process will throw a debug exception and control will return GDB. For my debug server, it won’t. Why? Following in my debug server
