Bug Description

In the UEC, the CC uses avahi-publish to announce the existence of a cluster on the network. If the CC is registered, however, it will add the 169.254.169.254 address to the local interface, and for reasons we cannot determine, this interferes with avahi-publish to the point where nodes cannot see the published service using 'avahi-browse -at' any longer.

We're considering a fix in Eucalyptus itself whereby we restrict the 169.254.169.254 assignment to be link-local, which allows the avahi-publish to function again (we're assuming that avahi-publish is only choosing globally scoped subnets to broadcast on?)

This fix is in testing now (Oct11/2009)

This bug was fixed in the package eucalyptus - 1.6~bzr930-0ubuntu1

eucalyptus (1.6~bzr930-0ubuntu1) karmic; urgency=low

  [ Dustin Kirkland ]
  * debian/eucalyptus-url, debian/eucalyptus-cc.install,
    debian/eucalyptus-cc.links, debian/eucalyptus-cc.postinst::
    - 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-cloud.eucalyptus-cc-registration.upstart,
    eucalyptus-cloud.eucalyptus-sc-registration.upstart,
    eucalyptus-cloud.eucalyptus-walrus-registration.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
  * eucalyptus-common.eucalyptus.upstart: fix unclean package purging,
    which hangs on stopping eucalyptus service

  [ Upstream ]
  * Merge upstream revision 930
  * This snapshot is expected to fix the following bugs:
    - LP: #449944 - fixes remote component bootstrap issue
    - LP: #430852, #401996 - fix handling of security groups for the admin
    - LP: #449948 - fix issues with network index and address recovery after
      a system restart
    - LP: #398867 - fix storing VLAN tag info from web ui
    - LP: #430266 - fix setting of HTTP error codes
    - LP: #449948 - part of fix to LP:#449948 the CC now correctly sets the
      networkIndex field in the reponse message of describeInstances
    - LP: #438565 - allowing a range of IPs to be specified in the
      VNET_PUBLICIPS field of eucalyptus.conf
    - LP: #449143 - Add the 169.254.169.254 address to eth0 as 'scope link'
      in order to avoid conflict with the UEC avahi-publish mechanism
    - LP: #449135 - Prevents a segfault in CC during client connection to NC
      on describeInstances, when number of instances is high (> 20 or so).
      The number of bytes sent to 'malloc' was being calculated incorrectly.
