Subject: [PATCH v3 5/5] tests/acceptance: Linux boot test for record/replay
Date: Tue, 27 Jul 2021 11:45:40 +0300 [thread overview]
Message-ID: <162737554047.1735673.13133593401566029378.stgit@pasha-ThinkPad-X280> (raw)
In-Reply-To: <162737551207.1735673.5022919664900932604.stgit@pasha-ThinkPad-X280>
From: Pavel Dovgalyuk <Pavel.Dovgaluk@gmail.com>
This patch adds a test for record/replay, which boots Linux
image from the disk and interacts with the network.
The idea and code of this test is borrowed from boot_linux.py
This test includes only x86_64 platform. Other platforms and
machines will be added later after testing and improving
record/replay to completely support them.
Each test consists of the following phases:
- downloading the disk image
- recording the execution
- replaying the execution
Replay does not validates the output, but waits until QEMU
finishes the execution. This is reasonable, because
QEMU usually hangs when replay goes wrong.
