How do I use Symfony doctrine:fixtures:load with multiple entity managers?

php symfony doctrine entitymanager fixtures

After Phils comment I moved all my Fixtures into a FixturesBundle and did this

php app/console doctrine:fixtures:load --fixtures=src/Incompass/FixturesBundle/DataFixtures/ORM

For the Blog Fixtures I also had to specify the entity manager

php app/console doctrine:fixtures:load --fixtures=src/Incompass/BlogBundle/DataFixtures/ORM --em=symblog
