Attempted to do this using netcat + ssh and here's my next problem. The
CentOS server is using LVM, so instead of getting an img file of around
8 gig that I expected, I got one that is 18 gig, or the size of the LV.

I tried it anyway and I get a valid boot sector not found.

Any suggestions?

Xen uses a partition within a partiton.  If you are going from a real system to a xen and they are both on lvms do something like

lvcreate -n xenBoot -L <a little bigger than the real servers lvm>G /dev/VolGroup00
fdisk /dev/VolGroup00/xenBoot
  create a primary partion

kpartx -a /dev/VolGroup/xendBoot  <this will make the partition visible to dom0 in /dev/mapper/xenBoot1

dd if=/dev/VolGroup/<your real boot volume> of=/dev/mapper/xenBoot1

 

Thanks,
James
