Description RHOS Integration 2015-02-05 13:59:40 UTC
Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/libvirt-real-time.


The CPU pinning feature added to the ability to assigned guest
virtual CPUs to dedicated host CPUs, providing guarantees for
CPU time and improved worst case latency for CPU scheduling.
The real time feature builds on that work to provide stronger
guarantees for worst case schedular latency for vCPUs.
