For centos, dd-ing the disk (not the partition) would probably give
you a working HVM domU, assuming you use labels or LVM path.
To get it working as PV domU, you need a different kernel
(kernel-xen), initrd, and some config adjustments to get it to
recognize the console. See http://pastebin.com/f6a5022bf
