keir & harper, You know, currently alloc_domheap_pages try to alloc mem from the node where current LP sit, which is not always right. E.g some hypercall issued from dom0's LP allocate memory for other domains. This patch intend to resolve this issue on NUMA system by locating node from the served domain. A new interface alloc_domheap_pages_on_node is introduced instead of changing current implementation, which is invasive. There are still many places left for the new interface, but we can change them in a incremental way if needed. Appreciate your comments. -- best rgds, edwin Attachment:
