Are you sure the file system image is populated correctly? I presume the
file system is ext3 rather than something fancy? What happens if you
mount it from dom0 and look at sbin/init?

This error is usually harmless, and just indiciates that you haven't
installed modules for your xen kernel on the new partition. Once you've
got the system booted you should be able to log in and install the
modules.

Alternatively, if you want to install before rebooting use: 
 make INSTALL_DIR=/temporary_mnt_point_of_new_file_system install
