I would have first installed a minimal RH7 on the disk image, then made a backup of /boot and /boot/grub/grub.conf. Also on my original rh7 I would have installed a xen kernel using : rpm -ivh kernel-xen?????.rpm. (the same as the one running on my xen system) Then copied all the files, like you did (using tar and ssh). Then restoring /boot/grub/grub.conf and kernel related /boot/initrd????? Et voila :-) Anyway the hardest part is to have grub correctly installed and a well configured initrd pre-boot image.
