I only took look at elilo code so that I don't know how distros handle relocations. I don't think relocation harms current dom0 builder as long as the loading address is properly chosen.

I don't understand this comment. I think it's quite feasible to support NUMA with current memory model. The pseudo physical address model is independ of NUMA support. Presumably you have many patches locally behind this patch.

thanks. -- yamahata
