More or less, yes. You forgot the initrd module statement in grub.conf. 
So the kernel misses the device mapper module ("driver") that is in the 
initrd.
Just add "module initrd /initrd-<version>.img" to grub.conf.  You might 
need to create it with the mkinitrd command if it is not in /boot already.
BTW. Why are you using Xen 3.1?
