I would prefer people using HybridFox plugin in Mozilla Firefox for managing instances and images in Eucalyptus.

You can get it from this link

http://code.google.com/p/hybridfox/

Jus open this file using Firefox in “Open with” option while you right click on the file (.xpi).

This is a simple tutorial which doesnt cover EBS.Get your credentials from your cloud admin or generate a new key pair from the Euca Web Interface.

SCP your key

Syntax: scp -i yourkey.private euca2-xxxxxxx-x509.zip root@xxx.xxx.xxx.xxx:/mnt

Get an instance of the existing image running on one of the Node controllers.

Install rsync from yum repo

yum install rsync unzip

Unzip your credentials to /mnt,or which ever file system that has enough disk space.

unzip euca2-admin-x509.zip -d euca/

Source your scripts

. /mnt/euca/eucarc

Install Euca2ools

http://open.eucalyptus.com/wiki/Euca2oolsCentosInstall_v1.1

Bundle your image

euca-bundle-vol -c ${EC2_CERT} -k ${EC2_PRIVATE_KEY} -u ${EC2_USER_ID} --ec2cert ${EUCALYPTUS_CERT} --no-inherit --kernel eki-KKKKKKKK --ramdisk eri-RRRRRRRR -d /mnt -r ARCH -p NEW_IMAGE_NAME -s SIZE_IN_MBs -e /mnt,/root/.ssh,OTHER_DIRS_TO_EXCLUDE

where

eki-KKKKKKKK -> same as with running instance
eri-RRRRRRRR -> same as with running instance

Upload the Bundle

euca-upload-bundle -b BUCKET_NAME -m /mnt/NEW_IMAGE_NAME.manifest.xml

Synchronize your time (if error occurs )

yum install -y ntp
ntpdate pool.ntp.org

Register the bundle

euca-register BUCKET_NAME/NEW_IMAGE_NAME.manifest.xml
