'''
External inventory script for Abiquo
====================================
Shamelessly copied from an existing inventory script.
This script generates an inventory that Ansible can understand by making API requests to Abiquo API
Requires some python libraries, ensure to have them installed when using this script.
This script has been tested in Abiquo 3.0 but it may work also for Abiquo 2.6.
Before using this script you may want to modify abiquo.ini config file.
This script generates an Ansible hosts file with these host groups:
ABQ_xxx: Defines a hosts itself by Abiquo VM name label
all: Contains all hosts defined in Abiquo user's enterprise
virtualdatecenter: Creates a host group for each virtualdatacenter containing all hosts defined on it
virtualappliance: Creates a host group for each virtualappliance containing all hosts defined on it
imagetemplate: Creates a host group for each image template containing all hosts using it
