A Debian GNU/Linux Wheezy Beta 2 AMI is uploaded to OpenStack. It really is an Ext4 file system that OpenStack will resize to use all the size of the primary disk of the instance. An AMI is made of three files, the kernel (the AKI), the ramdisk (the ARI) used at boot time and the file system to boot from (the AMI). In OpenStack, the AMI is specified to the nova boot … –image command line.
