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.
