similar to: NUMA support on Xen ?

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

Hi all, As part of IPv6 version specific classification support in crossbow we are introducing ip_version option in flowadm interface and associated classification functions. If ip_version option is not specified, but v4 or v6 address is passed as arg. to ip_addr option of flowadm cli that can also help to populate version specific bits in flow_mask to specify if policy (and flow entry

Hi, I'm trying to manually create a rhel7 image using the qemu-img and virt-install commands. I'm re-testing a procedure I previously wrote with the new grub commands that a customer suggested we add in. This procedure is available at: http://file.bne.redhat.com/dnavale/docs/review/RH-guides/AG-020715/#sect-create-images As in the procedure, I'm able to run all steps successfully

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

Hi, I have a couple of questions. - I am a new libvirt code user. I have just cloned the repo and I am looking for a suitable debugger/IDE which will help me debug the code. - I work in developing and creating virtual printers with display, with QEMU as the hypervisor (no KVM-only Qemu). Currently we have our own application to manage the virtual printers. Our plan is to migrate to

Hi Rich, I'm not sure how far this helps as it mostly says 'No space left on device', but here's the output of the command you asked me to run: ➜ tmp /usr/bin/supermin --build -v -v -v --copy-kernel -f ext2 --host-cpu x86_64 /usr/lib64/guestfs/supermin.d -o /tmp/appliance.d supermin: version: 5.1.9 supermin: rpm: detected RPM version 4.11 supermin: package handler: fedora/rpm

Hi , I'm looking for a possibility to simulate a VM (to be used as a host) reporting no or empty NUMA <cells> in 'virsh capabilities'. 'virsh capabilities' usually reports single NUMA in the VMs, like <numa> <cell id='0' cpus='0-63' memory='16777216' unit='KiB'/> </numa> I appreciate if someone could advise Thank you

Hi all I just ran these tests on my network and came up with these results. I found it interesting and thought I would share. In all test the same 2.5 Gig logfile was used for transfer (2719312019 Nov 12 11:42 maillog.back) (2.5G Nov 12 11:42 maillog.back) The transfer was done over two Gigabit nic's one onboard broadcom on IBM X440 server, Other Intel on standard selfbuilt dual P3 880

i''m reading up on numa usage. so far, i''ve enabled numa on my Xen box. @ Dom0 i see, xm dmesg | grep -i numa (XEN) Command line: ... numa=on ... (XEN) No NUMA configuration found i guess i need to ''configure'' numa. i''ve no clue how, and haven''t found the docs for it yet, despite looking. i found this old thread,

Hi folks, we are using a Tyan TK8W 2885 Mainboard (latest BIOS) w/ 2 Dual Core Opteron 280EE and 8GB of RAM (4GB per Socket). Furthermore we run CentOS 5.1 w/ Xen 3.2.1. (build from SRPM). We also tried 3.2.0. I tried both, the CentOS 5.1 Xen Kernel as well as the latest RHEL 5.2 Kernel but we do not get two NUMA domains as we (in my opinion) are supposed to. Do we need to recompile anything?

Hi, should NUMA be enabled in the BIOS of a server that has two sockets but only a single CPU in one of the sockets? From what I?ve been reading, it is unclear to me if NUMA should be enabled only on systems with multiple CPUs in multiple sockets or if multiple cores of a single CPU in a single socket benefit from NUMA being enabled, and if memory access in general benefits from NUMA being

Hello all, I was recently trying out NUMA placement for my guests on both x86_64 and ppc64 machines. When booting a guest on the x86_64 machine, the following specs were valid (obviously, just notable excepts from the xml): <memory unit='KiB'>8388608</memory> <currentMemory unit='KiB'>8388608</currentMemory> <vcpu

Hi, I'm running into some problems with libvirt and hoping someone can point me at some instructions or maybe even help me out. First, are there any requirements on qemu version in order to use the "numatune" and/or "cpu/numa/cell" elements? Or do they use cgroups and not the native qemu numa support? Second, are there any instructions on how to set up cgroups? I
