[PATCH 4/6] xen: export NUMA topology in physinfo hcall
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 : node0:0x0000000000000000-0x0000000190000000

[PATCH] nr_cpus calculation problem due to incorrect sockets_per_node
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:

[PATCH] xm info
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. Here is the output of new "xm info": -- system : Linux host : ubuntu xen_release

[PATCH] valgrind: Support for ioctls used by Xen toolstack processes.
Please CC as I''m not subscribed to valgrind-developers. Under Xen the toolstack is responsible for managing the domains in the system, e.g. creating, destroying, and otherwise manipulating them. To do this it uses a number of ioctls on the /proc/xen/privcmd device. Most of these (the MMAPBATCH ones) simply set things up such that a subsequenct mmap call will map the desired guest

[PATCH] dom0_ops -EPERM not -EACCES?
Hi all, dom0_ops return -EACCES when the interface version in wrong. I think that an acm failure is closer to being non-priv''ed, which returns -EPERM. Wouldn''t want dom0 tools to report they were the wrong version just because ACM limited some operation, surely?

[PATCH] 0/7 xen: Add basic NUMA support
The patchset will add basic NUMA support to Xen (hypervisor only). We borrowed from Linux support for NUMA SRAT table parsing, discontiguous memory tracking (mem chunks), and cpu support (node_to_cpumask etc). The hypervisor parses the SRAT tables and constructs mappings for each node such as node to cpu mappings and memory range to node mappings. Using this information, we also modified the

[patch] testing needed: "xenif" dom0_ops
This patch changes the dom0_ops structures as discussed in the thread "32/64-bit hypercall interface". Keir, I added a struct inside XENIF_PTR() to catch direct users in the general code; it was quite useful to have the compiler identify those spots. I have compiled x86_32 and run it with xm-test[1] under qemu. There are 63 passed tests, so that''s good. I still need to

[PATCH] 0/2 VCPU creation and allocation
I''ve put together two patches. The first introduces a new dom0_op, set_max_vcpus, which with an associated variable and a check in the VCPUOP handler fixes [1]bug 288. Also included is a new VCPUOP, VCPUOP_create, which handles all of the vcpu creation tasks and leaves initialization and unpausing to VCPUOP_initialize. The separation allows for build-time allocation of vcpus which

[Patch] Enable "sysrq c" handler for domU coredump
Hi, In the case of linux, crash_kexec() is occured by "sysrq c". In the case of DomainU on xen, Help is occured by "sysrq c" now. So The way of dumping DomainU''s memory manualy is nothing. I fix this issue by the following way. 1. Panic is occured by "sysrq c" on both Domain0 and DomainU. 2. On DomainU, coredump is generated in /var/xen/dump (on Domain0).

[PATCH 00 of 16] libxl: autogenerate type definitions and destructor functions
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

[PATCH] xenpm: make argument parsing and error handling more consistent
Specifically, what values are or aren''t accepted as CPU identifier, and how the values get interpreted should be consistent across sub-commands (intended behavior now: non-negative values are okay, and along with omitting the argument, specifying "all" will also be accepted). For error handling, error messages should get consistently issued to stderr, and the tool should now

[PATCH 2/6] xen: add per-node bucks to page allocator
This patch adds a per-node bucket to the heap structure in Xen. During heap initialization the patch determines which bucket to place the memory. We reserve guard pages between node boundaries in the case that said boundary isn''t already guarded by the MAX_ORDER boundary to prevent the buddy allocator from merging pages between nodes. -- Ryan Harper Software Engineer; Linux Technology

Today I installed another server using the same method (they are identical servers). I just did a yum update and I found something curious. Both servers have a different kernel.
