Nodes are the physical systems within UEC that actually run the virtual machine instances of the cloud.

Once one or more Ubuntu Server node(s) are installed and running the eucalyptus-nc service, log onto the Cloud Controller and run:

• sudo euca_conf --no-rsync --discover-nodes

This will discover the systems on the network running the eucalyptus-nc service, and the administrator can confirm the registration of each node by its IP address.

• Note: If you get prompted for passwords, or receive errors from scp, you may need to revisit the key synchronization instructions at UEC/NodeInstallation.
