Hello, I created a blueprint for the implementation of:

A tool for pinning automatically each running virtual CPU to a physical
one in the most efficient way, balancing load across sockets/cores and
maximizing cache sharing/minimizing cache misses. Ideally able to be run
on-demand, as a periodic job, or be triggered by events on the host (vm
spawn/destroy).

Find it at https://blueprints.launchpad.net/nova/+spec/auto-cpu-pinning

Any inputappreciated!

Thanks
