Description RHOS Integration 2013-12-12 14:16:10 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/improve-nova-kvm-io-support.

Description:

The goal here is to provide a new IO options for KVM disks. By default OpenStack uses the default libvirt/kvm option which is io='threads'. While attaching a volume based on a block device and not a file it's often recommended to use io='native' which brings significant lower CPU usage and generally better IO performance.
