Regarding to the question, I found one tool named as tracef. http://binary.nahi.to/hogetrace/#dl It's in Japanese. The tool can trace the functions called by qemu while recompling qemu with exra options like -finstrument-functions. It's just like strace and ltrace, but used to trace userland function. Attach it to qemu, and the result can be got. For exmaple: [pid 26180] do_info_cpus() at 0x08056870 so do_info_cpus is used while you call "info cpus". Currently tracef only supports x86 arch. Hope this will help someone. Best Regards, robert
