Eucalyptus Beginner’s Guide – UEC 10.10 & Eucalyptus 2.0-Image Management

with 2 comments

We have noticed a few changes in the way Eucalyptus 1.6 (UEC on Ubuntu 10.04 Lucid Lynx) and 2.0 (UEC on Ubuntu 10.10 Maverick Meerkat) launch instances. These changes have an impact on the bundling procedure. This article takes these changes into account and may be helpful for users of UEC on Ubuntu 10.10 and Eucalyptus 2.0

Eucalyptus Machine Image(EMI)

A Eucalpyptus Machine Image(EMI) is a combination of a virtual disk image(s), kernel and ramdisk images as well as an xml file containing meta data about the image. These images reside on WS3 and used as templates for creating instances on UEC. Each Linux EMI is a combination of the following:

  • An XML file with a name like “jaunty.img.manifest.xml” with information about one or more hard disk images, a kernel image and a ram disk image (id – emi-65440E7E)
  • An XML file with a name like “vmlinuz-2.6.28-11-server.manifest.xml” with information about the corresponding kernel image(id – eki-39FC1244)
  • An XML file with a name like “initrd.img-2.6.28-11-server.manifest.xml” with information about the corresponding ramdisk image(id – eri-71ED1322)

Each of these images has its own ID that can be used while running the instances. More on this in the chapter on “Managing Instances” Read the rest of this entry »
