This commit adds some basic pinning logic that will allow us to make pinning placements taking into consideration hyperthreading capabilities of the host (and instances if set). _numa_fit_instance_cell_with_pinning is the central method that will be called for each NUMA cell that will eventually be called from numa_fit_instance_to_host for instances that will require explicit CPU pinning. None of the methods here are meant to be exposed as public methods to be called outside of numa_fit_instance_to_host, however since they contain all the placement logic it is useful to test them separately. Change-Id: Ia846437f315bceb21d7ffd0cdfdd905a0b2d546d Blueprint: virt-driver-cpu-pinning
OpenStack Nova README
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.
OpenStack Nova is distributed under the terms of the Apache License, Version 2.0. The full terms and conditions of this license are detailed in the LICENSE file.
Nova primarily consists of a set of Python daemons, though it requires and integrates with a number of native system components for databases, messaging and virtualization capabilities.
To keep updated with new developments in the OpenStack project follow @openstack on Twitter.
To learn how to deploy OpenStack Nova, consult the documentation available online at:
For information about the different compute (hypervisor) drivers supported by Nova, read this page on the wiki:
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 wishing to work on the OpenStack Nova project should always base their work on the latest Nova code, available from the master GIT repository at:
Developers should also join the discussion on the mailing list, at:
