Comment 18 for bug 458904

Documented at <https://wiki.ubuntu.com/KarmicKoala/ReleaseNotes#UEC%20Node%20Controller%20installation%20failure%20in%20an%20existing%20UEC>:

Extending an existing Ubuntu Enterprise Cloud may fail during node controller installation started using the "Install Ubuntu Enterprise Cloud" option on the server CD. The node installation reports that the preseed file cannot be downloaded from the Cluster Controller, because the wrong IP address is used to connect to the Cluster Controller.

As a workaround for this issue, users can install a standard Ubuntu 9.10 server and then install the {{{eucalyptus-nc}}} package after reboot. Additionally, the system's primary ethernet interface will need to be configured as a bridge and the public ssh key of the Cloud Controller's eucalyptus user will need to be manually copied into the {{{authorized_keys}}} file of the Node Controller's eucalyptus user. More detailed instructions can be found in Step 3 of the UEC Package Install tutorial at [[https://help.ubuntu.com/community/UEC/PackageInstall]]. (Bug:458904)
