Comment 1 for bug 1908096

We've seen this again a few more times in the last month or so:

https://solutions.qa.canonical.com/bugs/bugs/bug/1908096

Including this test run: https://solutions.qa.canonical.com/testruns/testRun/b1588957-d3f4-44cd-8267-5f23363b907a

I imagine it's probably the root cause for this issue: https://bugs.launchpad.net/charm-nova-cloud-controller/+bug/1898581 but I need to go through the logs from the linked runs on that bug.
