Hi, i'm new to eucalyptus. i have just set up the both cluster and node controller. i was following the stephttp://open.eucalyptus.com/wiki/EucalyptusImageManagement_v1.6#top to upload a prepackage image but i encountered this problem. Would like to know how do i set this part of the configuration (set the printed eki to $EKI) and (set the printed eri to $ERI) as i have no idea how to go about setting it. Thanks in advance.
