[CentOS] 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.
