Does the LV show that it's open (or ever changes state) when the VM attempts to boot? Did you try taking a snapshot of the LV and mucking around with the xen configuration to see if anything changes? Did you update anything else on the machine, like perhaps the BIOS? Can you mount the VM's filesystem? Is its partition table okay? How about the boot loader?
