You have been subscribed to a public bug:

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)
