Description

Launch an instance on OpenStack.

Setup

Optionally include information on preparing the test environment

1. Follow QA:Testcase_download_and_register_tty_images_with_OpenStack
2. Make sure the nbd kernel module is loaded so that injecting SSH key files into the filesystem on the qcow2 image works:

$> sudo modprobe nbd 

How to test

Launch an instance of one of the images downloaded and registered in the previous test case.

$> cd ~/novacreds
$> euca-run-instances ami-tty --kernel aki-tty --ramdisk ari-tty -k nova_key
