+**Host variables:**

+Since Vagrant ???, the [`host_vars`](/v2/provisioning/ansible_common.html) option can be used to set [variables for individual hosts](http://docs.ansible.com/ansible/intro_inventory.html#host-variables) in the generated inventory file (see also the notes on group variables below).

 **How to generate Inventory Groups:**
 
 The [`groups`](/v2/provisioning/ansible_common.html) option can be used to pass a hash of group names and group members to be included in the generated inventory file. It is also possible to specify [group variables](http://docs.ansible.com/ansible/intro_inventory.html#group-variables).
