The idea is that "-smp" does not migrate and if we run source and destination guests with different numbers in -smp, we end up with weird machine because interrupt server properties (gserver?) in the device tree are different and no reconfiguration happens (no such mechanism as I know) the whole XICS behaves different. The patch just prevents migration from succeeding which seems better. -- Alexey
