The Walrus service is provided by the eucalyptus-walrus package.

If this service is running on the same system as the eucalyptus-cloud service, then registration occurs automatically.

Otherwise, you need to manually register walrus with the eucalyptus-cloud service by defining the walrus IP address, and starting the registration job.

On the Cloud Controller:

• Define the shell variable WALRUS_IP_ADDR in /etc/eucalyptus/eucalyptus-ipaddr.conf, as a single IP address.

Then, on the Cloud Controller, run:

sudo start eucalyptus-walrus-registration
