Do we really need to rename it ? Various bits of code do uniqueness checks
on both name & uuid. If we rename it, though uuid checks still work, any such
checks on the name will not be correct. IMHO, if shutdown fails we should just
leave the guest alone completely. The admin knows that they requested a
shutdown,
and can clearly see that after 'n' seconds it is still around & can take the
appropriate action - admins already know to watch for failed shutdowns since
this stuff happens on bare metal too. Renaming to 'report' error just seems
wrong to me & will potentially confuse tools.
