Bug Description

In MANAGED-NOVLAN mode (default Ubuntu Eucalyptus networking mode), the cluster controller provides a DHCP (static addressing) server. No other DHCP server handing out dynamic addresses should be enabled on the network (ie, on the router, etc).

In this case, the installation of the Node will not automatically detect a DHCP address. The user will need to manually set a static address.

However, the /etc/network/interfaces written by eucalyptus-udeb.finish-install is non functional. The default configuration handles a DHCP eth0 properly, but not a static eth0.

I can understand why br0 would need to be static rather than dhcp. I don't understand why the static network configuration needs to go on br0 rather than on eth0, though; this just seems weird, especially with 'bridge_ports eth0'. Can you explain this for the hard of thinking?

I'm sorry, I can't.

I massaged this configuration until I got it to work as expected.

 a) system can talk out to the network, ping, resolve names, etc.
 b) the network can talk to the system, ping, ssh, wake-on-lan
 c) the cloud can deploy vm's to the system, with their networking properly bridged.

Perhaps your network configuration knowledge here is a bit deeper?

  * debian/eucalyptus-url, debian/eucalyptus-cc.install,

    - fix whitespace, to match other update-motd urls LP: #450449
    - link to ubuntu.com/cloud, which links to our documentation,
      necessary for new UEC admins
    - ensure that it gets installed with executable permissions,
      LP: #444970
  * debian/eucalyptus-udeb.finish-install: fix typo; fix breakage of
    /etc/network/interfaces when nodes are configured with static IP
    addresses, LP: #446023
  * eucalyptus-cc.upstart,
    eucalyptus-sc.upstart, eucalyptus-walrus.upstart, rules, control:
    - registration of cc/sc/walrus should *only* ever occur on the CLC,
      so these scripts should be moved to the eucalyptus-cloud package,
      LP: #450815
    - starting cc/sc/walrus should *not* depend on eucalyptus-cloud
      running, since these components can be installed on separate
      machines, LP: #450777
    - but if cc/sc/walrus are on a system doing registration, ensure that
      these jobs kick off when "starting" registration
    - allow for whitespace separated list of $CC_IP_ADDR and $SC_IP_ADDR,
      as there can be more than one of these, and admins in multi-cluster
      or multi-component mode would need to register a list
    - use Replaces to ensure upgrades work properly
  * debian/eucalyptus-ipaddr.conf: update inline documentation accordingly
  * debian/eucalyptus-cc.templates: update public_ips instructions in the
    installer to match the new upstream implementation, LP: #438565
