Matt Riedemann a039f83977 Document unset/reset wrinkle for *_allocation_ratio options 
This is a follow up to I43a23a3290db0c835fed01b8d6a38962dc61adce
which makes the cpu/disk/ram_allocation_ratio config "sticky" in
that once set to a non-default value, it is not possible to reset
back to the default behavior (when config is 0.0) on an existing
compute node record by unsetting the option from nova.conf. To
reset back to the defaults, the non-0.0 default would have to be
explicitly put into config, so cpu_allocation_ratio=16.0 for example.

Alternatively operators could delete the nova-compute service
record via the DELETE /os-services/{service_id} REST API and
restart the nova-compute service to get a new compute_nodes record,
but that workaround is messy and left undocumented in config.

OpenStack Nova

OpenStack Nova provides a cloud computing fabric controller, supporting a wide variety of compute technologies, including: libvirt (KVM, Xen, LXC and more), Hyper-V, VMware, XenServer, OpenStack Ironic and PowerVM.

Use the following resources to learn more.

API

To learn how to use Nova's API, consult the documentation available online at:

For more information on OpenStack APIs, SDKs and CLIs in general, refer to:

Operators

To learn how to deploy and configure OpenStack Nova, consult the documentation available online at:

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:

Developers

For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst.

Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests.

Further developer focused documentation is available at:

Other Information

During each Summit and Project Team Gathering, we agree on what the whole community wants to focus on for the upcoming release. The plans for nova can be found at:
