 - The default LXD image supported by Travis CI is Ubuntu Xenial 16.04 and by using `dist` you can select different supported LXD images. Also see our [CI Environment Overview - Virtualisation Environment vs Operating System](https://docs.travis-ci.com/user/reference/overview/#virtualisation-environment-vs-operating-system) documentation. The LXD host, on which LXD-based builds are run, is on Ubuntu 18.04.
 - The amd64 CPU architecture build job currently runs as a regular 'full VM' and will be transitioned to an LXD compliant Linux OS image usage over time.
