If you want to use custom query, you have to set query_builder option as follows:

...

$form = $this->createFormBuilder($message)
             ->add('group', 'entity', array(
                   'class' => 'Vendor\MyBundle\Entity\Group',
                   'label'=>'Group:',
                   'query_builder' => function(EntityRepository $er) {
                       return $er->createQueryBuilder('g')
                                 ->... // whatever you want to do
                       }
                    ))
             ->getForm();

You can find more info about query builder in Doctrine manual and about options for entity in Symfony2 manual.
