Subject: [Qemu-devel] [PATCH 0/3] Deterministic replay extensions
Date: Tue, 09 Feb 2016 08:55:07 +0300 [thread overview]
Message-ID: <20160209055506.8208.67.stgit@PASHA-ISP> (raw)
This set of patches is related to the reverse execution and deterministic
replay of qemu execution. It includes recording and replaying of serial devices
and block devices operations.
With these patches one can record and deterministically replay behavior
of the system with connected disk drives and serial communication ports
(e.g., telnet terminal).
