It sounds like you may be running a *-user target because softmmu
(system emulation) has no knowledge of file I/O inside the guest.
Please give more details of what you're trying to do if this is
incorrect.
It sounds like you want strace together with -d in_asm output. Have
you seen linux-user/strace.c?
