Nova

OpenStack Nova provides a cloud computing fabric controller, supporting a wide variety of virtualization technologies, including KVM, Xen, LXC, VMware, and more. In addition to its native API, it includes compatibility with the commonly encountered Amazon EC2 and S3 APIs.

Documentation and Bugs

To learn how to deploy OpenStack Salt, consult the documentation available online at:

https://wiki.openstack.org/wiki/OpenStackSalt

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:

http://bugs.launchpad.net/openstack-salt

Developers wishing to work on the OpenStack Salt project should always base their work on the latest formulas code, available from the master GIT repository at:

https://git.openstack.org/cgit/openstack/salt-formula-nova

Developers should also join the discussion on the IRC list, at:
