Balazs Gibizer 5af28c4de5 Support interface attach with QoS ports
The following logic is added to the ComputeManager attach_interface
flow:

* gather the resource request of the port from neutron
* query allocation candidates restricted to the current compute node
  from placement
* extend the existing allocation of the instance with one of the
  allocation candidates in placement
* update the InstancePCIRequest (if any) to ensure that the PCI claim
  only allocates VF from the PF the placement resources are allocated from
* ensure that during port binding neutron gets the RP UUID, the resources
  are allocated from, in the allocation key of the binding profile

This patch bumps the compute service version to indicate that QoS
interface attach is supported. Also the check that was so far rejected
such attach is now updated to only reject it if the compute service
version is too old.

The "scheduling" during interface attach for PCI backed ports has the
same limitation as normal scheduling for such ports. It always selects
the first allocation candidate returned by placement even if later in
the process it turns out that such allocation candidate points to a PCI
PF that has no free VFs left.

OpenStack Nova

image

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, 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:
