similar to: [PATCH] xm info

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

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 : node0:0x0000000000000000-0x0000000190000000

This patch extends libxc for few new functions on xen version and xen compile info. It also extends python wrapper correspondingly. Here is the output of new "xm info" --- #xm info system : Linux host : ubuntu xen_release : 3.0-devel xen_compile_by : root@localdomain xen_compiler : gcc version 3.3.5 (Debian 1:3.3.5-8ubuntu2)

Hello, Earlier this week I installed a test server with CentOS 5.6 with Virtualization enabled during the installer. 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. Server 1 is at 9.1 version and server 2 at 5.1. How can this be? How to I get the latest version on

You need to add dom0_mem=XXXm to xen or scale back the memory of domain0 with using "xm mem-set <DomId> <Mem>" command. Your domain0 used up almost all physical mem. >total_memory : 1023 >free_memory : 62 Thanks Yunfeng >-----Original Message----- >From: xen-devel-bounces@lists.xensource.com

Hello, I have a big problem: Dom0 is centos5.1, domU are centos5.1. My setup is really simple, the only thing is that I give 3 nics to the domU so I use a modified network script (which has worked since january... since fedora 6): " #!/bin/sh dir=$(dirname "$0") "$dir/network-bridge" "$@" vifnum=0 "$dir/network-bridge" "$@" vifnum=1

I have a OpenSuse 10.3 with xen 3.1.0 running and it''s been running fine for a few months. This past weekend it suddenly started to act up and after some troubleshooting I can now say that it seems like the guests(domU) loose the outgoing network pipe, from the console I can see that the TX counter is stuck at the same value but it''s no errors. It behaves as if whatever I try to

Hello , I use Centos 5.4 , with the redhat version of xen . I need for some guest to change the hardware for the network . So in my xen config i add the model option in the vif line . When the guest boot , i had the right emulation , but after a reboot , the guest loose the configuration . Someone can confirm the bug in centos 5.5 ? Have someone a patch ? Extract of my config : builder

I just upgraded my Fedora Core 5 Xen server from 1 gig or memory to 2. When I start the machine it begins to load the Xen kernel and then reboots. I can boot the machine on straight FC5 without Xen. If I put it back to 1 gig of memory Xen will boot fine. I looked in the xend.log and didn''t see anything. I do see some kind of page_fault error on the screen before the server reboots.

Hi there, I am new to Xen. Just began trying it out from day-before. I have a CentOS 4.4 install on my hda6 partition. And I have a openSUSE 10.2 install on my hda8 partition. For openSUSE 10.2, I chose the Xen options while installing, and so I have the xen kernels too installed. For CentOS 4.4, I downloaded the Xen 3.0.2 source and compiled from there. (I followed the instructions at this

I am thoughly confused with the various Xen 3.0.3 versions for Suse. Firt there is not for suse 10.1, so I gues I woulllt the source tarball and compile.
