If that's the aim then perhaps the xm command should be given a better name.
'xm os-init' is rather meaningless outside the context of physical INIT
buttons on ia64 systems -- not a very generic concept to export to a VM
management tool! Perhaps 'xm os-dump' with a guest-specific backend
implementation in xend (default to fail with an error message).
