A new PCI resource handler is added to the update_available_resources code path update the ProviderTree with PCI device RPs, inventories and traits. It is a bit different than the other Placement inventory reporter. It does not run in the virt driver level as PCI is tracked in a generic way in the PCI tracker in the resource tracker. So the virt specific information is already parsed and abstracted by the resource tracker. Another difference is that to support rolling upgrade the PCI handler code needs to be prepared for situations where the scheduler does not create PCI allocations even after some of the compute already started reporting inventories and started healing PCI allocations. So the code is not prepared to do a single, one shot, reshape at startup, but instead to do a continuous healing of the allocations. We can remove this continuous healing after the PCI prefilter will be made mandatory in a future release. The whole PCI placement reporting behavior is disabled by default while it is incomplete. When it is functionally complete a new [pci]report_in_placement config option will be added to allow enabling the feature. This config is intentionally not added by this patch as we don't want to allow enabling this logic yet. blueprint: pci-device-tracking-in-placement Change-Id: If975c3ec09ffa95f647eb4419874aa8417a59721

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 and OpenStack Ironic.
Use the following resources to learn more.
API
---
To learn how to use Nova's API, consult the documentation available online at:
- `Compute API Guide <https://docs.openstack.org/api-guide/compute/>`__
- `Compute API Reference <https://docs.openstack.org/api-ref/compute/>`__
For more information on OpenStack APIs, SDKs and CLIs in general, refer to:
- `OpenStack for App Developers <https://www.openstack.org/appdev/>`__
- `Development resources for OpenStack clouds
<https://developer.openstack.org/>`__
Operators
---------
To learn how to deploy and configure OpenStack Nova, consult the documentation
available online at:
- `OpenStack Nova <https://docs.openstack.org/nova/>`__
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:
- `Bug Tracker <https://bugs.launchpad.net/nova>`__
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:
- `Official Nova Documentation <https://docs.openstack.org/nova/>`__
- `Official Client Documentation
<https://docs.openstack.org/python-novaclient/>`__
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
