When the bits tests are run, bits binaries are downloaded from an external repo/location, bios bits iso is regenerated containing the acpi/smbios bits tests that are maintained as a part of the QEMU source under tests/avocado/acpi-bits/bits-test . When the VM is spawned with the iso, it runs the tests in batch mode and the results are pushed out from the VM to the test machine where they are analyzed by this script and pass/fail results are reported.
