+As a last option, you can also choose hostmanager as a provisioner.
+This allows you to use the provisioning order to ensure that hostmanager
+runs before or after provisioning. The provisioner will collect hosts from
+boxes with the same provider as the running box.
+
+Use:
+
+```ruby
+config.vm.provision :hostmanager
