Hi, Please let me know in case I am posting my question to the wrong forum. I apologize if that is the case! Here is my question: We run CentOS 6.3 on a server with dual Xeon CPU's. Our "dual blade" server uses this motherboard: http://www.supermicro.com/products/motherboard/Xeon/C600/X9DRT-HF.cfm We have two of these CPUs installed and working: Intel(R) Xeon(R) CPU E5-2620 0 @

Hi all, What are the differences between pc and q35?? By default, virt-manager+libvirt setups kvm guest machine as a pc-i440fx-rhel7.1.0. [hicheck at ckvm015 ~]$ /usr/libexec/qemu-kvm -machine ? Supported machines are: pc RHEL 7.1.0 PC (i440FX + PIIX, 1996) (alias of pc-i440fx-rhel7.1.0) pc-i440fx-rhel7.1.0 RHEL 7.1.0 PC (i440FX + PIIX, 1996) (default) pc-i440fx-rhel7.0.0

Hello I have recently had to reinstall Centos 7.5 to on host computer. I have not be able to set-up qemu to support the q35 chip set. I have several virtual machines that require q35. This is not my first install, I have configured libvirt on many machines in the past, it just worked, it has not required any manual configuration. [root at sj aadmin]# /usr/libexec/qemu-kvm -machine help

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.

Almost exactly two years ago, I released the first tutorial for building an HA platform for KVM VMs. In that time, I have learned a lot, created some tools to simplify management and refined the design to handle corner-cases seen in the field. Today, the culmination of that learning is summed up in the "2nd Edition" of that tutorial, now called "AN!Cluster Tutorial 2".

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 Guys, Just found an issue with CentOS 6.3. The network is getting inaccessible at times. The server has been installed with CentOS 6 and then package upgrade was performed. = [~]# cat /etc/redhat-release CentOS release 6.3 (Final) [~]# = = [~]# uname -r 2.6.32-279.5.2.el6.x86_64 [~]# = The server is up for most of the time. But the next day when we check the server is inaccessible over

Hello I have Debian Linux 2.6.32-5-xen-amd64 Xen 4.0.1, 2 SAS drives in RAID 1, 16GB ram. I have virtualized Windows 2003R2 32bit where you install the latest version 0.11.0.295 gplpv After reading and reading forums and post testing, I noticed that the hard disk performance drops significantly when I assign the windows domU 9GB ram. (below I leave the config files) If I run the

Hello I use KVM. In a virtual machine "jbd2 dm-0" disk I / O is very increases. It consumes up to 99%. For this reason, slowing down the other virtual machine. What should I do to solve the problem. ? Thanks..

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 have two KVM hosts (CentOS 7) and would like them to operate as High Availability servers, automatically migrating guests when one of the hosts goes down. My question is: Is this even possible? All the documentation for HA that I've found appears to not do this. Am I missing something? My configuration so fare includes: * SAN Storage Volumes for raw device mappings for guest vms

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:
