I think this is the real bug:
we are checking a behaviour that we cannot achieve currently.

As you said in this thread, we could think about how to free it properly
in a future release.
For 19.08, I would suggest to disable the test with a comment
explaining the reason.
> Workaround this by disabling pci scan.
If you choose the --no-pci workaround, please add a comment
about the reason.
