The following says that no displays were auto-detected.
See this post for details:

The following is normal unless you're running a kernel
that supports device-tree (3.5.7+):

Cool! It looks like you're booting now.

Do you have an ethernet cable connected?
Does the network have a DHCP server?

If the answer to both questions is yes, this is probably a
timing issue. The Gb ethernet port on SABRE Lite is pretty
slow to link, and sometimes the DHCP will time out before
that occurs.

I have no idea what may be happening with the avahi-daemon.

At this point, it appears that Yocto is fully booted.
