I don't quite understand your question, but if what you want is
scheduler policy that always schedules instance to physical node has
least load (AMB # of vCPU), then SimpleScheduler is the answer.

Or, since you talked about 'process two command at the same time', are
you looking for a multprocess Nova API service? Like this
