Comment 5 for bug 1673483

Ok, basic verifications were all good, I faced no issues on automated tests on all sort of libvirt interactions as well as migrations from/to/in-between xenial. I also have not seen any arch difference.

This means I would have two ppa's for you to try:
- Backport of the minimal recommended fix: https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/2620
- Backport of the full series of related fixes: https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/2619

Is there a reasonable way to expose that in your infrastructure - although I'm afraid "2 hits in 7 days" make this hard to feel 100% sure that "0 hits in 7 days" is a safe validation. But you know your environment best - is there a way to test these to gain some confidence - in this being a fix as well as not causing another regression?
