Merge remote-tracking branch 'remotes/cleber-gitlab/tags/python-next-pull-request' into staging

Acceptance Tests

- Fix for tests/acceptance/virtio-gpu.py to match the change in device
  name
- Fix for failure caught by tests/acceptance/multiprocess.py

PS: While not a maintainer for the subsystem in PATCH 7, I'm including
it as a one-off to facilitate the landing of the fix as discussed in
the mailing list.
