Always look for the FetchError:

Varnish can't reach your backend. Since there's no 'Backend' record
anywhere in your log, Varnish evidently doesn't know about any backend
that it can connect to.

Take a look at the start script invoked by 'service'. If you haven't
changed anything about it, I would guess that it's not using the VCL
file specified by -f in your command, but rather a "default" VCL that
defines a backend that doesn't exist.
