Public bug reported:
Overview
Eucalyptus-cc fails to register nodes when you leave blank, i.e., don't
specify DNS settings. This is experienced when setting up static addresses
during the Ubuntu installation process.
How to reproduce the issue:
1. Choose "Install Ubuntu Enterprise Cloud"
2. Instead of using dhcp settings configure static addresses for eth0 and leave
the dns field blank
3. After the installation try to register a node using:
$ sudo euca_conf --register-nodes <ip-of-the-node>
It says that the node has been registered however CC is unable to list them
when running:
$ sudo euca_conf --list-nodes
4. Looking at the cc.log you will get something like this:

====
Workaround:
1. Open /etc/eucalytus/eucalytus.conf and uncomment VNET_DNS parameter and set
proper dns entries.
2. VNET_DNS="8.8.8.8"
3. sudo restart eucalyptus-cc CLEAN=1
Proposed Solution #1
1. Make DNS Field mandatory during the installation process for the option
"Install Ubuntu Enterprise Cloud" since the installation will be using
MANAGED-NOVLAN anyway.
OR
If field is left blank make sure the eucalyptus installer takes care of adding
a fake or public dns to the VNET_DNS variable.
This is experienced in Lucid and Natty. Maverick has not been tested.
