Overview
Record/replay feature is implementation of deterministic replay for system-level simulation (softmmu mode).
Record/replay functions are used for the reverse execution and deterministic replay of qemu execution. Determinitsic replay is used to record volatile system execution once and replay it for multiple times for the sake of analysis, debugging, logging, etc. This implementation of deterministic replay can be used for deterministic and reverse debugging of guest code through a gdb remote interface.
