Since we have CPU pinning support from my previous patch, adding in the
initial pinning is fairly easy. We first pass the '-S' arg to QEMU when
forking it. This causes it to initialize, but not start the CPUs in the
guest. We then set the affinity mask for all its CPUs, and then send
the 'cont' command to the monitor to start execution.
Does this include Xen support?
