First, please don't cross-post. It's impolite.
You want to modify an emulator. QEMU or Bochs would be a good start.
The only way to trace an applications execution at the instruction level
in Xen would be put it in debug mode which you have said is not a
possibility. Xen always runs application code on bare-metal.

Hi,
I am fairly new to xen.
I have installed Xen to solve the following problem:
I want to run an arbitrary binary in a sandboxed environment (like
virtual machine) and get the execution trace ( that is all the
instructions executed while running) of the application. With this
execution trace, I am developing algorithm to compare with the static
disassembly to check for mismatch and find out possibility of the
binary being a malicious software.
However I do not how to get the entire execution trace of an
application in Xen. It would be great if some one can suggest how to
get the execution trace on xen.
Obviously I don't want to run the application under debug / ptrace,
because many malicious softwares are intelligent enough and act as
good guys when run under debug mode.
