How does one make the dedication of a CPU to dom0?   Seems like pincpu is 
the control mechanism, but if I understand pincpu correctly, it doesn't 
prevent other domains from sharing the chosen CPU.   It pegs the domain to 
the CPU, but not the reverse.   Also, how can one distinguish an ht CPU vs a 
core CPU?
