  • Tips and tricks to improve memory paging on servers

    Memory paging helps virtual machines share a server's memory resources nicely, but can throttle performance. A few simple tricks will optimize paging. 

  • Using KVM virtualization in the enterprise: RHEV or RHEL?

    They sound alike, but RHEV and RHEL are pretty different. Red Hat’s KVM virtualization products offer different levels of KVM management capabilities. 

  • How to improve KVM performance by adjusting KSM

    KVM Virtualization on Red Hat Enterprise Linux 6 is optimized for hosting environments with many virtual machines by using kernel samepage merging. But, disabling KSM can provide better performance in a smaller virtualized Linux system. 

  • SUSE Manager for Linux virtualization systems management

    Novell's new systems management tool, SUSE Manager, runs as a software appliance in a virtualized environment. Learn how to install and configure SUSE Manager in a Linux XenServer system. 

  • Using Vagrant with Puppet to create VirtualBox hosts

    Vagrant integrates with Puppet and Chef to automate configuration management to build VirtualBox hosts. Linux systems admins can use this technology for quickly creating development hosts and production hosts. 

  • Ganeti clustered virtualization on Linux

    Ganeti is a tool for managing virtual instances across a cluster. Learn how to install this open source cluster-management tool on your Linux system using Xen as the hypervisor, and get it to work on a two-node cluster. 

  • Optimizing SUSE Linux performance for VMware environments

    Learn how to optimize Suse Linux Enterprise Server (SLES) on VMware by optimizing VMware and SUSE. For better performance, switch to VMware's paravirtualization disk driver and adjust I/O settings in SUSE along with changing the journal settings. 

  • Red Hat optimizes RHEL 6 kernel for virtualization

    In Red Hat Enterprise Linux 6, some specific enhancements will be made to the kernel to optimize it for KVM. In some cases, these improvements will provide near-native performance for virtual machines. Xen will no longer be supported. 

  • Weighing Linux server consolidation tools

    Choosing the best Linux server consolidation software for your data center hinges on factors other than cost. This tip compares Novell's PlateSpin, HP and VMware's Capacity Planner in terms of your data center requirements. 

  • Booting a Xen virtual machine from CD-ROM or DVD

    If your Xen virtual machine fails, you may want to boot it from an installation disk and run the rescue program. Learn the required steps to succesfully boot a Xen virtual machine from a disk on a Linux machine.
