I've played a bit. Attached patch here has logging done with logger in an effort to serialize things.
Then, I have 'go.sh' (see below) that just loops over running test-mic until it fails. Then you get bookend messages in /var/log/syslog. I've collected a fail here. ** Patch added: "test-logger.patch: applied to 318 for 'logger' based logging." https://bugs.launchpad.net/ubuntu/+source/cloud-utils/+bug/1741096/+attachment/5030703/+files/test-logger.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1741096 Title: test-mic can fail / writes to qemu-nbd device do not persist To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-utils/+bug/1741096/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
