I have a 2 way machine.  Soliciting folks opinion on whether
it makes sense to smp enable DOM0 so that IO handling can be
balanced over both CPU's...

Its generally not helpful to have an SMP dom0. In high IO situations
it's typically best to dedicate a hyperthread or core to dom0.

Ian

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?
