all have numa_node set to -1. Only the devices on the pxb can have a
sensible value specified.
Does it mean, the emulated devices/drivers don't care about the
numa_node they are on?
Would it be fine on PPC to disallow setting the NUMA node for the
default PHB because that is where
all the emulated devices sit ?
I was not aware of that limitation for x86 guests.
If that's the case, then I would say it's perfectly okay to
just disallow setting the NUMA node for the default PHB, at
least for the time being.
