Add an option 'iothreadpin' to the <cpuset> to allow for setting the CPU affinity for each IOThread.
The iothreadspin will mimic the vcpupin with respect to being able to assign each iothread to a specific CPU, although iothreads ids start at 1 while vcpu ids start at 0. This matches the iothread naming scheme.

We ought to do a followup patch that adds an <interleave>, so that all sub-elements of <cputune> can come in any order. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
