Currently flavor option is checked after performing the image checks which results in unnecessary image checks even if flavor option is not passed at all. Moved flavor option check at the beginning of the method to eliminate the expensive operations performed as part of image check.

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.

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/v2/
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, 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.
