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.
