Use relative paths:

  code10:~ # xenstore-read vm
  /vm/0fa9cb1b-1275-7027-9cab-80089db40ed4
  code10:~ # xenstore-read domid
  1

That's it.  But adding a watch for these doesn't work (at least it
didn't last time I tried), so you can't easily get notified in case the
domid changes due to migration or save/restore.
