Ok, I think we can manage dimm numa placement for user if numa is enabled.
(Just find numa node with less memory to add this dimm module).


For the display, do you want to display dimm device like another device ?



>>How is that handled by other plattforms (vmware, xen, vbox)? 
I'll try to find some informations about them.

Form my point of view, this is much too complex. I just want to add RAM and CPU 
cores, 
but I do not want to care about NUMA architecture or DIMMs. Many users are not 
familiar with 
those concepts. 

How is that handled by other plattforms (vmware, xen, vbox)?
