Title:
  multi instace display name did not follow template

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  
      cfg.StrOpt('multi_instance_display_name_template',
                 default='%(name)s-%(uuid)s',
                 help='When creating multiple instances with a single request '
                      'using the os-multiple-create API extension, this '
                      'template will be used to build the display name for '
                      'each instance. The benefit is that the instances '
                      'end up with different hostnames. To restore legacy '
                      'behavior of every instance having the same name, set '
                      'this option to "%(name)s".  Valid keys for the '
                      'template are: name, uuid, count.'),

  Try to boot two VMs in one request, then no index in vm display name.
