[libvirt] FreeNodeMemory

Hi Is there a specific reason for not having a "free_memory" with in the "virNodeInfo" structure. I can see there is "virNodeGetFreeMemory(connection)" which currently not implemented for XEN.. I can add the patch to do this.. But I would like to clarify why we have not add "free_memory" in to the virNodeInfo structure..
