How do I create a Eucalyptus image? Whats the difference between AMIs and EMIs?
As of v1.4, Eucalyptus images are synonymous with images used by Xen, which are disk partitions. If you can use an image/kernel/ramdisk combination with Xen, then you should be able to get it to work with Eucalyptus. (In fact, we recommend testing the image/kernel/ramdisk combination before going through the bundle/upload process.) The convention used on EC2, which Eucalyptus follows, is that the VM can expect three SCSI disks in the following arrangement: sda1: root partition (that is where the EMI is attached) sda2: “ephemeral” partition (for additional storage) sda3: swap partition You can either change your root partition to follow that layout (this is the recommended approach) or you can modify the Eucalyptus script that determines VM parameters such as disk layout (gen_libvirt_xml). With that in place, any Xen image should work. If there is an AMI that you’d like to try in Eucalyptus, you need to be able to download and unbundle it. Next you need to find the kernel/ramdisk combin
