Let's be careful not to go in circles. It seems you have "broken" configuration - no DNS servers are provided to the cloud image. So none are configured. Previously, systemd package provided a fallback DNS resolvers for that case. Then it stopped doing that. Now the circles - the change in systemd package was the outcome of discussion here on -devel list. In this discussion some people had a position "if I do not provide DNS servers, I don't want DNS to work". Which is resonable and expected in high-control situations. Providing the workaround again would go against wishes of those people. From their perspective your non-resolving cloud image is exactly as you want it.

Or dig deeper: why cloud-init disabled DNS on your installation? -- Tomasz Torcz “(…) today's high-end is tomorrow's embedded processor.” to...@pipebreaker.pl — Mitchell Blank on LKML _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
