A new-enough kernel m ( > 2.6.38 IIRC) *should* have support for Xen PV mode, because Xen front-end support has become part of the kernel; no need to patch.
However, whether a distro's kernel actually was compiled with Xen front-end support... now, that's the question. If you have /proc/config.gz, try see how the kernel was compiled.
If the kernel wasn't compiled with Xen front-end support, you'll have to acquire your distro's kernel sources and configure+compile your own kernel.

I've already installed Xen hypervisor over CentOS 6.0. I am wondering where can I obtain some patched guest OS kernels to get start. It seems that under PV mode, guest kernel needs to be modified (correct me if I am wrong). I am a newbie and have no previous experiences on Xen so any suggestions are appreciated.
