I tried several ways but still no help. The following are the output (stock Centos 6 2.6.32-71.29.1.el6.x86_64 kernel), grub works fine and it located kernel and initial ramdisk. but kernel booting faied at the very beginning...
Any suggestions are more than appreciated.

Subject: EC2 compatible kernel for centos 6?
Hi all,
I'm just scrambling to collect clues to build an Amazon AWS AMI based on Centos 6. the AWS PV-GRUB kernel loads my kernel but failed immediately. I'm using stock Centos 6 kernel 2.6.32-71.29.1.el6. and the kernel seems have xen? support? My questions are:
1, Are the centos 6 stock kernels, like kernel-2.6.32-71.29.1.el6.x86_64, EC2 compatible?
2, If the answer to the above #1 question is NO, the are the centos plus kernels, like kernel-2.6.32-71.29.1.el6.centos.plus.x86_64, EC2 compatible?
3, If the answers to both above are 'NO', then Are there any instructions to build a EC2 kernel based on kernel source RPMs?
Any help are greatly appreciated.
