The XML format allows for an initial CPU mask to be specified for a guests vCPUs. eg with this XML:

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?

cpu pinning is already support for xen. - Cole
