# Author: bgstack15
# Startdate: 2017-12-14
# Title: Script that Generates the vcenter matrix
# Purpose: Generate a list of all virtual guests and their uuids in the provided vcenters
# History:
# Usage: Populate vcenters.txt with the list of vcenter hosts to check. The script will use the same credential for all the vcenters.
# Document:
# Reference:
# file descript 10 https://unix.stackexchange.com/questions/107800/using-while-loop-to-ssh-to-multiple-servers
# web problem with vcenter api is because of escaped characters in variables https://github.com/ansible/ansible/issues/32477
# Improve:
# Accept parameters or environment variables for the input text file or even the credentials
# Document:
# Variables
