Very old, probably doesn't have a xenified version of the kernel.

I assume that means you copied the whole disk, not just a partition.

Since there is probably not a xen version of the kernel, you want hvm, so you
are missing the lines:
kernel = "/usr/lib/xen/boot/hvmloader"
device_model = "/usr/lib/xen/bin/qemu-dm"
and the disk line should be as in your followup post:
disk = [ "phy:/dev/Vol_LVM/registro-2,hda,w",]
You probably don't need the root= line, then. The 'dd' got the MBR.
Good luck.
