With high probability, 32 hex chars that are the same can probably be 
considered 'wrong'.

Some details on how one could handle the different cases of valid/invalid 
UUIDs:

   libvirtd.conf                dmidecode               handling

        valid UUID        valid UUID      libvirtd.conf UUID overrides 
dmidecode's UUID
        invalid UUID    invalid UUID      generate a temporary one; new 
one after libvirtd restart
        valid UUID      invalid UUID      use valid UUID
      invalid UUID        valid UUID      use valid UUID
