It seems that "RUNNING" is not set for the eth0 device. 

Please disable "use-iff-running" in your avahi-daemon.conf. This
should fix the problem. Most (but unfortunately not all) network
drivers use this bit to tell userspace in an hardware independent
manor the status of the ethernet link beat.

i.e. if you set "use-iff-running" to "yes" you'll have link beat
checking in avahi, it will automatically detect when you plug in or
unplug the network cable. Some drivers never set this bit (like yours
as it seems) so avahi will never make use of the interface. 

I've changed the default setting of this variable to "no" now. This
way avahi should work out-of-the-box on most systems, though link
beat detection is lost.

avahi-discover never enabled that variable.

The avahi_server_add_service() error remains still to be fixed.
