[PATCH 9/9] tests/acceptance: Linux boot test for record/replay |
Date: |

StGit/0.17.1-dirty |
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
However, currently record/replay works only for x86_64,
therefore other tests were excluded.
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.
