Forgive me for not combing through all of the machine output, but at a
glance your symptoms look like something I have encountered where the
nbd server does not start automatically on the server. The quick fix
was to start the service, and then I don't recall if it started
automatically after a reboot or if I had to turn that on in a config
file somewhere. Try 'netstat -lt' to see what ports you're listening on.

Thanks for a good lead (though it leads to more questions rather than an
immediate solution).
I find that nbd-server is running, but comparing the output of 'netstat
-lt' on a Lubuntu 13.04 LTSP server that works fine, and the misbehaving
13.10 server, I find that on
13.04 nbd-server listens on *: 60603, but on 13.10 it listens on *:nbd.
Otherwise the output is the same for tcp on both servers (I don't list
the tcp6 results):
tcp 0 0 *:9571 *:* LISTEN
tcp 0 0 localhost:55213 *:* LISTEN
tcp 0 0 Lubuntu:domain *:* LISTEN
tcp 0 0 192.168.1.117:domain *:* LISTEN
tcp 0 0 localhost:domain *:* LISTEN
tcp 0 0 *:ssh *:* LISTEN
tcp 0 0 localhost:ipp *:* LISTEN
The nbd-server configuration file
(/etc/nbd-server/conf.d/ltsp_i386.conf) has the same contents on both
installations.
The script that launches nbd-server appears to be
/etc/init.d/nbd-server, and it does not specify ip addresses or ports to
listen to. At least for the ip addresses,
http://manpages.ubuntu.com/manpages/saucy/man1/nbd-server.1.html states
that when the ip address parameter is not specified, nbd-server will
listen on all local addresses on both IPv4 and IPv6.
I don't know how to interpret the difference in how nbd-server is listening.
