This also affects .ova cloud-image deployments on ESXi/vSphere, not surprising since it's similar to what John describes in comment 15. I think this is caused by the kernel parameter console=ttyS0 and the underlying VM having no serial port. This should not fail cloud-init and a similar bug was fixed in #1573095. Commit b794d426b9ab43ea9d6371477466070d86e10668 introduces a stdout fallback when /dev/console does not exist. How about doing that fallback also when writing fails?
