Hi all, I'm happy to announce a new tutorial! https://alteeve.com/w/2-Node_Red_Hat_KVM_Cluster_Tutorial This tutorial walks a user through the entire process of building a 2-Node cluster for making KVM virtual machines highly available. It uses Red Hat Cluster services v3 and DRBD 8.3.12. It is written such that you can use entirely free or fully Red Hat supported environments.

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

Just installed centos 6.2. I run and ifconfig -a I see and em1 em2 and lo interface. If I go to /etc/sysconfig/network-scripts, I don't see an ifcfg-eth0. If I run ifup eth0 it comes back with "Device eth0 does not seem to be present, delaying initialization". Anybody have a clue? Thanks in advance.

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

I just installed CentOS 6.2 32 bit today. When I try to start the Virtual Machine Manager I get a error: Packages required for KVM usage The following packages are not installed: qemu-kvm These are required to create KVM guests locally. Would you like to install them now? If I click on the [YES] button I'm told that the packages could not be found in any software source. [root at

Hi, I'm looking for some recommendations. I need to have some sort of high availability for a set of php & mysql web sites, they must be hosted on 2 servers, in separate data centres and obviously on differrent IPs. I can't use a load balancer because that will introduce a single point of failure making the "distributed setup" useless. I was thinking some sort of

Let's go ahead and get this flame thread started now to save time. The CentOS team sucks ... it took XXXX days to do 6.1 ... it is going to take twice as long to get 6.2 My mom said CentOS blows. kbsingh is ugly. hughesjr is old and fat. OK ... that should do. -------------- next part -------------- A non-text attachment was scrubbed... Name: signature.asc Type: application/pgp-signature

We are at the stage, finally, where we are prepared to deploy public facing VM guests. Now we have to answer these questions: How many guests in total should we contemplate and what services are placed on which guests? My question comes down to whether it is considered advisable to run the primary DNS and IMAP, or indeed all services, on separate vm guests; or should we continue, more or less,

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

I have been reading the threads on here with great ernest about redhat making a move to throw off centos compilations. I read some stories about microsoft wanting to work closer with centos http://www.theregister.co.uk/2011/05/17/microsoft_and_centos/ I have to update to centos 6 due to some needs of clients who need newer mysql and php (and installing them on centos5 was too hard for me). I

Hi all, With help from others, I''ve been able to get Olaf''s patch for enabling MTUs >1500 for vifX.y and tapZ devices working. I''ve been able to boot dom0, launch domU and live-migrate without having the bridge''s MTU degrade at any time. Would the Xen RPM maintainers (and others) mind taking a look at the following patches? Kernel part:

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

Hi: I have two HVM domU ubuntu 10.04 Lts and Window XP running. I have assigned PCIe device to each of this domU. I would like to communicate these two VM. Can anyone give me some idea on how to do. I did some research on IVC but unable to get answer. Anything will be appreciated. Anju _______________________________________________ Xen-users mailing list

Hello, If you''re interested in running Xen 4.0 hypervisor/dom0 on RHEL6, take a look at here: http://wiki.xen.org/xenwiki/RHEL6Xen4Tutorial It explains steps needed to rebuild Xen 4.0.1 src.rpm from Fedora on RHEL6, and how to fetch dom0 capable 2.6.32.x kernel from upstream git repository. It also shows how to get libvirt/virt-manager working with Xen on RHEL6. Hopefully it helps :)

Hi All, After digging through the xen wiki, the recommendation I have found so far for first time virtualization testing of XEN is to use Centos. Do I get to choose which XEN hypervisor version I want to run?...e.g if I want the latest (XEN 4.1) At the moment I am using a liveCD - feeling my way around Linux environment (newbie here as well)... Any pointers to set me in the right direction

Hi all, One of our domU VMs (CentOS 5.6 x86_64) runs a cobol application, which in turn called ''clock'' to get timestamps. Changing this is non-trivial. When I try to call ''clock --debug'' I get: [root@vm0010 ~]# clock --debug hwclock from util-linux-2.13-pre7 hwclock: Open of /dev/rtc failed, errno=19: No such device. No usable clock interface found.

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.
