Using dump-guest-memory sounds more complicated than needed.

No, this is important, since i can have a whole image to do offline analysis.
You can
just use the monitor commands for disassembling that address

What is this command? I try "help" but cannot find any. Before I remember we had "disas" or something like that, but I cannot find that again in latest Qemu code.
or the
built-in gdb stub (-s).

Is this true that this only works for pure emulator, not for kvm-enable VM?
