I debugged by myself and saw the script to create the loaderdisk variable is not correct

loaderdisk="$(mount | grep -i optional | grep cde | awk -F / '{print $3}' | uniq | cut -c 1-3)"

it should be

loaderdisk="$(mount | grep -i optional | grep cde | awk -F / '{print $3}' | uniq | cut -c 1-4)"

because the partions in the Xen VM is something like this
/dev/xdc
-> /mnt/xdca1
