hi, Some of you might have seen the email on the centos-devel list, for the rest I just wanted to point out that we've been working on getting opennebula ( http://www.opennebula.org/ ) rpms and contextualised images for opennebula available with a very low barrier to entry for CentOS. The 'win' with OpenNebula is that its easy to install, easy to get going, scales well and mostly

Hi everybody, I am using Opennebula 3.6 on a Debian Squeeze system. My configuration: Node-A kvm --version QEMU emulator version 1.0 (qemu-kvm-1.0 Debian 1.0+dfsg-8~bpo60+1), Copyright (c) 2003-2008 Fabrice Bellard virsh --version 0.9.11.3 Node-B kvm --version QEMU emulator version 1.0 (qemu-kvm-1.0 Debian 1.0+dfsg-8~bpo60+1), Copyright (c) 2003-2008 Fabrice Bellard virsh --version

Hello, ok, I found that cpu pinning was wrong, so I corrected it to be 1:1. The issue with iozone remains the same. The spec is running, however, it runs slower than 1-NUMA case. The corrected XML looks like follows: <cpu mode='host-passthrough'><topology sockets='8' cores='4' threads='1'/><numa><cell cpus='0-3'

Hi everyone I'm trying to create a virtual machine using OpenNebula [1] on a centos 6.4 server, but i'm facing some erros using kvm / libvirt. This server is running on a virtual machine created on XCP. Then, my infrastructure is: XCP 1.6 (hypervisor - dom0) + CentOS 6.4 (running on a XCP VM) + OpenNebula 4.0.1 (installed on CentOS). In the host machine, I have the same infrastructure.

hi, i am trying to install xen hypervisor for opennebula on centos 6. 1. i tried installing in it but when i reboot the system with xen kernel the system doesn''t get booted. 2. i tried it again on a different system and now the package for xen is not available for yum installation. please provide me a proper set of instructions as to how to install xen hypervisor for opennebula.

Hello libvirt users, I'm using the cgroup with QEMU guests. At /etc/libvirt/qemu.conf, I have the following parameter: cgroup_controllers = [ "cpu" ] This controller is successfully mounted and libvirt is able to create subgroups for each VM, it's really great the cgroups support in libvirt. The problem is that I can only set the parameters of a given cgroup under the cpu

Hey John, Hehe, I got the right guy then. Very nice! And very good ideas but I may need more time to reread and try them out later tonight. I'm fully in agreement about providing more details. Can't be accurate in a diagnosis if there isn't much data to go on. This pool option is new to me. Please tell me more on it. Can't find it in the file below but maybe it's

Hi, folks, I'm Rich Bowen, and I work with the OSAS (Open Source and Standards) group at Red Hat, as a community guy for OpenStack. In my other life, I've been on the documentation team for the Apache httpd project for a few years, so I like to think I can write coherently. ;-) I'd like to request edit privs on the CentOS wiki. In particular, I wanted to make edits to the page

Hi, How are bricks healed in Debian Jessie 3.11? Is it at the file of block level? The scenario we have in mind is a 2 brick replica volume for storing VM file systems in a self-service IaaS, e.g. OpenNebula. If one of the bricks is off-line for a period of time all the VM files systems will all have been modified when brick comes back on-line. As some of these VM file systems are quite

Hello guys, maybe you can help me with following issue. I have created a little cloud with a host and two worker nodes using opennebula. The setup went successfully until now, I am able to create VM's and move them via normal and live migration. Another (possibly) important information is that I configured my virtual bridge on both worker nodes like this: auto br0 iface br0 inet static

Can you provide some more details with respect to which libvirt version you have installed. I know I've made changes in this space in more recent versions (not the most recent). I'm no root_squash expert, but I was the last to change things in the space so that
