Hello all, In order to test and debug a linux-based real-time system, I'd like to hook it up to a software simulator, which sadly does not run fast enough to meet the real-time constraints.
To workaround this problem, I had the idea of running the real-time system in guest whose clock would be controlled by the simulator, running on the host. Alas, I found no API for doing so with qemu. Yet, it seems qtest does it (I found qtest_clock_step [1] etc.) Is it possible or at least conceivable to control (and slow down) the guest time externally? Where should I look to get some insight on that matter? Note that this question was asked previously [2], [3], but never answered.
