When using pygrub, start the guest with "xm create -c" or "xm start
-c", and you can edit the grub menu to add "single".
If the domU is using kernel and initrd from dom0, you should be able
to add "extra=single" on domU config file.

As Stefan said, it might be easier to check for the missing file by
fsck and mounting domU's filesystem from dom0. Be sure to do this ONLY
while domU is stopped though. If it was indeed missing, then most
likely you're experiencing a serious problem and the missing file is
just the tip of the iceberg. I highly suggest you call a Linux expert
to help fix the problem.
If you insist on restoring the file manually, you need to know :
- which packages were damaged, what version (something like "rpm -V"
and "rpm -qa" on chroot or single mode)
- get the original package.
- extract it and copy the missing package
If you don't know how to perform the above steps, it would be easier
to simply create a new domU and copy data from the old one.
