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 »

Eucalyptus Networking

System

In System mode, CC generates and assigns a random MAC address to the VM instance while requesting NC to bring up the instance. NC attaches the VM instance’s virtual NIC to the physical NIC on the node through a bridge. This mode requires that the Nodes are connected to the enterprise network directly. Instances obtain an IP address using DHCP, just as physical machines on the network do.

This mode is very easy to setup as it does not have any additional prerequisites in terms of networking, except for a running DHCP server on enterprise network, and is a good way to get started with Eucalyptus, particularly if you want to set it up on your laptop/desktop to get a basic understanding.

This mode of networking is similar to “Bridged Networking” that hypervisors like VMware, VirtualBox etc. offer or like “tap” networking offered by KVM/Qemu.
