This reverts commit 4e79285b45ec1490c8e923f724cbaf4d42fe81c4. The aforementioned commit broke flavor-show for mixed case flavorids. The reason is a bit complex. On the nova api side, there is caching of db items for flavors, keyed off the flavorid retrieved from the db, case sensitive, unlike the db query itself. Attempts to flavor-show a flavor with flavorid composed of letters will fail with a 400 if the capitalization doesn't match. For the flavor names, they work in lowercase because the find_resource function falls back on a search by "human_id" after failing every other attempt to find the flavor, because "human_id" is a oslo-slugified string (all lowercase, non-word characters removed, spaces converted to hyphens). Closes-Bug: #1446850 Change-Id: I73247b50f5a6918167c071ccc13cd676aa2c7fec
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.
The project is hosted on Launchpad, where bugs can be filed. The code is hosted on Github. Patches must be submitted using Gerrit, not Github pull requests.
python-novaclient is licensed under the Apache License like the rest of OpenStack.

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=myprojectYou 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/v1.1/
export OS_COMPUTE_API_VERSION=2If 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, but it has not yet been documented.
To use with nova, with keystone as the authentication system:
# use v2.0 auth with http://example.com:5000/v2.0/")
>>> from novaclient.v2 import client
>>> nt = client.Client(USER, PASS, TENANT, AUTH_URL, service_type="compute")
>>> nt.flavors.list()
[...]
>>> nt.servers.list()
[...]
>>> nt.keypairs.list()
[...]
