Hmm, this was for the default case when NUMA is turned off in hypervisor.
After setting numa=on on xen command line, the result is a bit different:
nr_cpus : 48
nr_nodes : 8
sockets_per_node : 0
cores_per_socket : 12
threads_per_core : 1
node_to_cpu : node0:0-5
node1:6-11
node2:12-17
node3:18-23
node4:24-29
node5:30-35
node6:36-41
node7:42-47
sockets_per_node is reported to be zero.
