Comment 15 for bug 475354

Okay, worked on this a bit here today at the Distro Sprint.

We enabled Eucalyptus' DNS with: DISABLE_DNS="N" in /etc/eucalyptus/eucalyptus.conf.

This seems to work well enough to provide dynamically generated host names to vm's. See:

RESERVATION r-43AC08FE admin default
INSTANCE i-2DC5056F emi-DF7014F1 euca-172-19-1-2.eucalyptus.localhost euca-172-19-1-2.eucalyptus.internal running mykey 0 c1.medium 2010-02-03T22:14:40.651Z canyonedge eki-25291A19 eri-058C1996

So this gets us part of the way there.

HOWEVER, there's a major piece of this that cannot be solved without external configuration of your network's DNS.

Even though my instance might have hostname euca-172-19-1-2.eucalyptus.localhost, I cannot ssh to euca-172-19-1-2.eucalyptus.localhost without tweaking my DNS configuration.

For this reason, we cannot actually fix this bug within Ubuntu's Eucalyptus package. Rather, this will need to be solved in some how-to documentation under:
 * https://help.ubuntu.com/community/UEC/DNS

Upstream has some good docs at http://open.eucalyptus.com/wiki/DynamicDNSGuide. We'll base our guide on this, and tailor it for UEC.
