took a couple months off due to road blocks, hoping a fresh look would allow me to use my server as desired. I have three ports, eth0-2 over two nics. I want to bond them, and then use a bridge to connect to virtual machines on the virtual host computer. Never having done this, I am confused on some parts. Here is where I am at now and any pointers helpful. Single server, centos 6.x My issue

Are there any updated instructions for installing Windows virtio drivers on a KVM Windows XP vm under CentOS6? The virtio .iso directory structure is slightly different from what is described in the RHEL6 virtualisation manual, and when I attempt to install e.g. the viostor driver, the device manager cannot find anything better than what is already installed. I tried each of the

Hi all, Read many posts on the subject. Using 802.3ad. Few problems; Cannot ping some hosts on the network, they are all up. Cannot resolve via DNS which is one of the hosts that I cannot ping, internal nor external DNS hosts. Unplugging the NICS and plugging them back in will then not allow pining if the default d=gateway. When cold booting it somewhat works, some hosts are pingable while

Folks I have a new laptop running Centos 6.2 64-bit. I'd like to put a virtual machine running Windows 7 (licensed), with full audio/video functions, and good response. Which virtual system would you recommend? I can think of KVM, or VirtualBox, or ...? The "good response" requirement pretty much excludes a web-style video presentation. Opinions solicited.

Hello everyone, Does anyone know if it is possible to construct a cloud of sorts out of several CentOS machines so as to enable a VM (or several VM's) that would run on top of that cloud and have failover capability? Boris.

Hi all, Really enjoying KVM as I was a long time user of Xen. Both are cool, just enjoying the new thing. Wondering if any one could share some nuggets on how to get a Centos 5.1 VM guest to use virtio? Trying to use virtio over the ide. Thanks in advance, - aurf

I've got a Centos 5.8 box that I use for testing Xen VMs. I'm trying to setup some Centos 6.2 hosts in a high availability situation. I've tried the pacemaker route and couldn't get the connection established, so thought I'd try the RH-preferred methods. Mind you, all of these VMs are on the same host. Using Conga, it seems that I need some sort of fencing device, which

Hi, I need to create a real-time replication of a partition between two servers with centos 6.4, I am researching and finding difficulty with drbd, corosync, someone indicate material, do not need to run script automatically if a node drops only replicate. Grateful. -- Sergio.Alex

Hi, Wondering if this is the proper bridging technique to use for Centos6+KVM; http://wiki.centos.org/HowTos/KVM Before I embark on this again, I would like to do it by the book. Thanks in advance, - aurf

Hi all, I use CentOS5.x + Xen in production for virtualization. I use it with bridged vlan networks and bonding (active-backup) like that: eth0 eth1 | | ------- | bond0-------bond0.10---------bond0.12 ... | | | | vlanbr10 vlanbr12 dom0 | | ------------- -------------- | |

I'm creating a firewall HA cluster. The proof of concept for the basic firewall cluster is OK. I can bring up the cluster, start the iptables firewall, and move all of this with no problem. I'm using Conga to do all of this configuration on Centos 6.3 servers. To extend the "HA" part of this, I'd like to use bonded channels instead of plain old NICs. The firewall uses

Hi! I am building a KVM cluster that needs VM live migration. My shared storage as well as the KVM hosts will be running CentOS. Because 10 Gbps Ethernet switches are very expensive at the moment I will connect the KVM hosts to the storage by cross-over cables and create private networks for each connection (10.0.0.0/30 and 10.0.0.4/30). The following diagram shows the topology Management

Hi all. I am currently working for a hosting provider in a 100+ linux hosts' environment. We have www, mail HA solutions, as storage we mainly use NFS at the moment. We are also using DRBD, Heartbeat, Corosync. I am now gathering info to make a cluster with: - two virtualization nodes (active master and passive slave); - two storage nodes (for vm files) used by mentioned virtualization nodes

Hey folks, I just went through the archives trying to find some info on this but did not come up with much other than it seems there are a few experts here on the list. I have no experience with clustering and have just taken over a Stem Cell Research Lab that has a Grid Engine cluster. I have not yet dug into the details of Grid Engine (only been here a week now) but am just trying to get up

I'm desparately looking for more ideas on how to debug what's going on with our CLVM cluster. Background: 4 node "cluster"-- machines are Dell blades with Dell M6220/M6348 switches. Sole purpose of Cluster Suite tools is to use CLVM against an iSCSI storage array. Machines are running CentOS 5.8 with the Xen kernels. These blades host various VMs for a project. The iSCSI

Hi, I'm searching for "virtualization options". I already take a look on VMware, but it needs too much MS software to work for my needs. Citrix needs less, but the key validation is still MS-AD. Now I'm taking a look at RHEV... and run into Oracle VM! Somebody had already take a look at Oracle VM? We need in primary a solid VM solution for an "enterprise

In our development lab, I am installing 4 new servers, that I want to use for hosting KVM. each server will have its own direct attached raid. I'd love to be able to 'pool' this storage, but over gigE, I probably shouldn't even try. most of the VM's will be running CentOS 5 and 6, some of the VM's will be postgresql database dev/test servers, others will be

Hey folks, I had some general questions and when reading through the list archives I came across an iSCSI discussion back in February where a couple of individuals were going back and forth about drafting up a "best practices" doc and putting it into a wiki. Did that ever happen? And if so, where is it? Now my questions : We are not using iSCIS yet at work but I see a few places
