There's no xvda1 detected on your boot log.

Find out what your actual disk mappings are (again, whether from domU
config file, some kind of Amazon EC2 config page, ask Amazon support,
whatever). Don't bother doing anything else unless you ABSOLUTELY know
what your disk mappings are.

Since the fdisk output you show earlier show / and /boot on the same
disk, then simply assign that disk as xvda. Start from there. Don't
bother doing anything else unless you've succesfully done that (and
the boot log actually shows xvda is detected with the correct
partition).
