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.

Sample pillars
==============

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:

    https://wiki.openstack.org/wiki/Meetings/openstack-salt
