This is because `--mux-yaml` accepts multiple arguments, therefor it consumes the test as yet another argument, leaving the job with no tests to be discovered. See http://avocado-framework.readthedocs.io/en/latest/GetStartedGuide.html#running-tests for details but basically you have two options, explicit (using `--` to separate named arguments and positional arguments):

    avocado run --mux-yaml tests/acceptance/guest_abi.yaml -- tests/acceptance/guest_abi.py

or reorder (which is a bit hacky, but works)

    avocado run tests/acceptance/guest_abi.py --mux-yaml tests/acceptance/guest_abi.yaml
