Out of all of the systems above, I would personally have a strong preference
for GitLab simply because it is actually based on open source software.
Putting a critical part of QEMU's workflow on to a closed source service
whose infrastructure or terms of service could change at any time, feels
risky to me. With GitLab in the worst case we can spin up an instance on
our own hardware to run our test stack, especially if we are already
providing our own test runners.
