It's a resource-consuming task to implement full-flow (up to getting and reading a dump file) functional test for trigger-crash-dump. We need to upload Ubuntu image for booting an instance based on it, and to install kdump with its further configuring on this instance. Here, the "light" version of functional test is proposed. It's based on knowledge that trigger-crash-dump uses a NMI injection, and when the 'trigger-crash-dump' operation is executed, instance's kernel receives the MNI signal, and an appropriate message will appear in the instance's log. Wait_for_server_os_boot() method has been added to ClientTestBase to check if instance's operating system is completely booted. The _create_server() method has been removed since the change which puts this method to the base test class has been merged. Change-Id: I2313c5d37a7cf87a8d75e37c93aab136cf028ec1
Python bindings to the OpenStack Nova API
This is a client for the OpenStack Nova API. There's a Python API
(the novaclient
module), and a command-line script
(nova
). Each implements 100% of the OpenStack Nova API.
See the OpenStack CLI
guide for information on how to use the nova
command-line tool. You may also want to look at the OpenStack
API documentation.

Command-line API
Installing this package gets you a shell command, nova
,
that you can use to interact with any OpenStack cloud.
You'll need to provide your OpenStack username and password. You can
do this with the --os-username
, --os-password
and --os-tenant-name
params, but it's easier to just set
them as environment variables:
export OS_USERNAME=openstack
export OS_PASSWORD=yadayada
export OS_TENANT_NAME=myproject
You will also need to define the authentication url with
--os-auth-url
and the version of the API with
--os-compute-api-version
. Or set them as an environment
variables as well:
export OS_AUTH_URL=http://example.com:8774/v2/
export OS_COMPUTE_API_VERSION=2
If you are using Keystone, you need to set the OS_AUTH_URL to the keystone endpoint:
export OS_AUTH_URL=http://example.com:5000/v2.0/
Since Keystone can return multiple regions in the Service Catalog,
you can specify the one you want with --os-region-name
(or
export OS_REGION_NAME
). It defaults to the first in the
list returned.
You'll find complete documentation on the shell by running
nova help
Python API
There's also a complete Python API, with documentation linked below.
To use with keystone as the authentication system:
>>> from novaclient import client
>>> nt = client.Client(VERSION, USER, PASSWORD, TENANT, AUTH_URL)
>>> nt.flavors.list()
[...]
>>> nt.servers.list()
[...]
>>> nt.keypairs.list()
[...]
Testing
There are multiple test targets that can be run to validate the code.
- tox -e pep8 - style guidelines enforcement
- tox -e py27 - traditional unit testing
- tox -e functional - live functional testing against an existing openstack
Functional testing assumes the existence of a clouds.yaml file as supported by os-client-config (http://docs.openstack.org/developer/os-client-config) It assumes the existence of a cloud named devstack that behaves like a normal devstack installation with a demo and an admin user/tenant - or clouds named functional_admin and functional_nonadmin.
