QA:Testcase launch an instance on OpenStack

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

OpenStack in a Virtual Machine

If you are not testing OpenStack in a virtual machine, you may skip this section of the setup.

If you are testing OpenStack in a virtual machine, everything will have worked up to this point. However, launching an instance will fail unless you set an additional configuration option. Edit /etc/nova/nova.conf and add the following text to a new line in the configuration file:

--libvirt_type=qemu

After adding this item, you will need to restart the OpenStack services.

$> for svc in api objectstore compute network volume scheduler; do sudo service openstack-nova-$svc stop; done
$> for svc in api objectstore compute network volume scheduler; do sudo service openstack-nova-$svc start; done
$> for svc in api objectstore compute network volume scheduler; do sudo service openstack-nova-$svc status; done 

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

Expected Results

Verify that the instance has started.

$> euca-describe-instances 
RESERVATION	r-d8wpvydq	rbryant	default
INSTANCE	i-00000003	ami-00000003	10.0.0.2	10.0.0.2	pending	nova_key (rbryant, f16)	0		m1.small	2011-10-17T20:31:05Z	nova	aki-00000001	ari-00000002

$> sudo virsh list
 Id Name                 State
----------------------------------
 1 instance-00000003    running

Try SSHing into the instance:

$> cd ~/novacreds
$> ssh -i nova_key.priv root@10.0.0.2

Get conosle output:

$> euca-get-console-output i-00000003

Finally, terminate the instance:

$> euca-terminate-instances i-00000003
