13 Record/replay functions are used for the deterministic replay of qemu execution.
16 It also supports checkpointing for faster rewind to the specific replay moment.
20 Deterministic replay has the following features:
29 * Performs deterministic replay of all operations with keyboard and mouse
32 Usage of the record/replay:
38 -icount shift=auto,rr=record,rrfile=replay.bin \\
43 -object filter-replay,id=replay,netdev=net1
45 * After recording, you can replay it by using another command line:
49 -icount shift=auto,rr=replay,rrfile=replay.bin \\
