# What this is: A basic test to validate an OPNFV install. Creates an image,
# test_public and private networks, a router, and launches two VMs connected to the 
# private network and thru the router, to the internet.
#
# Status: this is a work in progress, under test. Automated ping test to the 
# internet and between VMs has not yet been implemented.
#
# How to use:
#   Install Congress test server per https://wiki.opnfv.org/copper/academy
#   $ bash ~/git/copper/tests/adhoc/smoke01.sh
#   After test, cleanup with
#   $ bash ~/git/copper/tests/adhoc/smoke01-clean.sh
