Read the documentation in qemu-doc.html.

Fabrice Bellard.

To run RECORD/REPLAY, follow the following steps:

1. Configure and compile qemu source,
cd qemu-0.13.0-rr && ./myconfigure && make clean && make

2. Create a qcow2 image for guest OS(say image.qcow2).

3. To run in RECORD mode,
./x86_64-softmmu/qemu-system-x86_64 -record filename[name of the record file] image.qcow2

4. To REPLAY the recorded sequence,
./x86_64-softmmu/qemu-system-x86_64 -replay filename[name of the record file] image.qcow2

Good luck! and please let me know about how you used this implementation.

thanks,
