Description
Launch an instance on OpenStack.
Setup
Optionally include information on preparing the test environment
- Follow QA:Testcase_download_and_register_tty_images_with_OpenStack
- 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
