Once Xen calculates nr_nodes properly, all nr_cpu calculations based on nr_nodes * sockets_per_node * cores_per_socket * threads_per_core are broken. The easy fix is to replace those calculations with a new field, nr_cpus in physinfo which is calculated by num_online_cpus(). This patch does so and attempts to change all users over to nr_cpus field in physinfo. This patch touches arch/ia64/xen/dom0_ops.c, but I''ve not done any IA64 testing with this patch applied. -- Ryan Harper Software Engineer; Linux Technology C...

Testing on an 8-node 128-way NUMA machine has exposed a problem with Xen''s nr_cpus calculation. In this case, since Xen cuts off recognized CPUs at 32, the machine appears to have 16 CPUs on the first and second nodes and none on the remaining nodes. Given this asymmetry, the calculation of sockets_per_node (which is later used to calculate nr_cpus) is incorrect:

This patch modifies the physinfo hcall to export NUMA CPU and Memory topology information. The new physinfo hcall is integrated into libxc and xend (xm info specifically). Included in this patch is a minor tweak to xm-test''s xm info testcase. The new fields in xm info are: nr_nodes : 4 mem_chunks...

This patch makes "xm info" show information on xen version, compile info, number of socket/core, etc... In order to do that, it extends physinfo hypercall to return number of socket, adds few functions to libxc and extends python wrapper correspondingly.

I got really strange situation with memory on host: xe host-list params=memory-free memory-free ( RO) : 10305536 (10Mb) xe host-compute-free-memory 3147059200 (3Gb) A huge difference! And xentop show different numbers too! I will keep this host online "as is" and I am ready to provide information for debbugging or perform needed actions. -- wBR,George.

a, libxl_event.h is included in libxl.h. So, the former one also need to be installed. b, define __XEN_TOOLS__ in libxl.h: the head file "xen/sysctl.h" need check this macro.

Returns free memory size per node in "xm info". This info can help users who want to bind their guest domain in one node of their NUMA machines thought set CPU affinity. I also write IA64 part support which I would send to XEN-IA64 mail-list. Thanks. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

...committed to xen-unstable, a guest can be constructed such that its entire memory is contained within a specific NUMA node. We''ve added a keyhandler for exposing some of the NUMA-related information and statistics that pertain to the hypervisor. We export NUMA system information via the physinfo hypercall. This information provides cpu/memory topology and configuration information gleaned from the SRAT tables to userspace applications. Currently, xend doesn''t leverage any of the information automatically but we intend to do so in the future. We''ve integrated in NUMA in...

The series introduces auto-generation of the type definitions used in the libxl interface followed by auto-generation of a destructor function for each type. In the future it may be possible to use the related data structures for other purposes, for example auto-generation of the functions to marshal between C and language binding data types. tools/_libxl_types.h should be identical both before
