Besides being unsure about the idea as such (I don't think Xen kernels have been knowing much about NUMA characteristics of the underlying machine), you're assuming that node IDs in kernel and hypervisor are identical, which I don't think is generally valid; XENMEMF_node(), afaict, is presently meant to be used by the Xen tools (and hypervisor internal users) only.
