AWS里面的centos AMI

AMI

An Amazon Machine Image (AMI) is an encrypted machine image that contains all information necessary to boot instances of your software.

use public AMIs as a base to create your own custom private AMIs.

可以理解为系统的一个模板。你可以基于这个模板启动多个系统实例，或者修改这个模板，做为自己的模板。

rightscale 是我认为比较好的第三方AMI提供者。提供cetos的AMI。

2、从vmware创建一个AMI

另外，kernel需要是xen的内核：The current hardware does NOT support hardware virtualization, so you need to build for Xen。In general, building for Xen, even on virtualizing hardware, can improve performance.

注：从本地上传做好的image到s3上时只需要上传 image.part.00 到 image.part.98和image.manifest.xml文件即可，大概1G左右，最大的那个3G左右的image文件不需要上传。

注：我按照上面的方法做了一个AMI，启动时出现了错误

FATAL: Could not load /lib/modules/2.6.16-xenU/modules.dep: No such file or directory 。
