Thank you, Ben. I have just searched again for similar questions, and found
what I think is the most "natural" solution:
Add this line to /etc/dhcp/dhclient.conf on the host:
prepend domain-name-servers 10.0.3.1;
Then run "service networking restart", and I can log into the guest with "ssh
ubuntu@guest1" or use "nslookup guest1".
HTH

I think that writing the address into /etc/hosts may cause you problems
eventually because it will get out of date when you remove containers and
potentially recycle addresses.
Stephane's solution has the advantage that it looks up the address dynamically
when you need it. I really like the idea of putting the look-up into
~/.ssh/config, especially because it allows you to other useful things like
turning off some security checking and setting the username.
If you don't like that solution because of the non-locality, you might prefer
to write a small script, say `lxc-ssh`:
$1=container
ssh $(host $container 10.0.3.1 | tail -1 | awk '{print $NF}')
