  • Microsoft Virtualization: Hyper V Live Migration Network configuration.

    Its quite hectic these days in Virtualization world as i am actively involved in planning Practice Accelerator for Virtualization. In addition to that I’ve been engaged in lots of Virtualization opportunities and whenever i speak to customers and partners, I tend to get lot of questions about setting up preferred network for Live Migration on Hyper V based clusters.

    Its highly recommended to use Cluster Shared Volume (CSV) while setting up the storage for Live Migration, CSV has following advantages:

    1. All the nodes in the cluster has concurrent access to the shared storage.
    2. Multiple VHDs can be stored on a single shared Volume.
    3. No Drive letter problems
    4. Faster failovers

    It looks like something like the diagram below, You can see in this diagram, that all the three nodes has simultaneous access to the same share running their respective VHD files. In the event of one node failure there is no drive ownership change and hence faster failover.


    By default, Cluster Shared Volumes (CSV) and Clustering use a private network with the lowest value for Metric property.  To prevent CSV and Clustering from sharing the same network with live migration, the default network order used for live migration is changed so that a network with the lowest value for Metric property is at the bottom of the list of networks for live migration.  This will reduce the possibility of CSV, clustering, and live migration using the same network.

    This helps ensure live migration speeds by placing live migration traffic in a separate network path.

    In the Failover Cluster Manager, right-click on the virtual machine and select Properties:


    By selecting the “Network for Live Migration” tab, you can specify what network is used for Live Migration. You can specify multiple networks in order of preference. For me, I normally have my 10 Gb/E network set as the first network.


    See this screenshot:


    Once you select the appropriate network, you will see the performance enhancement and decreased failover times However your Virtual Machine is always high available while its being migrated.

    I hope it helps, please feel free to reach me if you need more information.

    Microsoft has released IPD guide for Selecting the right Virtualization Technology.

    The Selecting the Right Virtualization Technology guide enables you to rapidly and accurately select which Microsoft virtualization technology or technologies to use for specific scenarios. There are several different forms of virtualization that need to be understood as a basis for making the right technology choice. This guide addresses the decision steps that need to be taken in order to select the best virtualization approach for specific application requirements. The most effective decision points in the sequence are presented for determining which virtualization technology should be used. When considering virtualization for multiple applications, you should iterate through the entire process individually for each type of application.

    In addition to this, documents on System Center Virtual Machine Manager 2008 R2 are now available.

    Following documents are now available to help you to Plan, design and deploy SCVMM 2008 R2.

    1. Virtual Machine Manager Deployment Guide: This guide provides information essential for the successful deployment of VMM 2008 and VMM 2008 R2. The topics in this guide provide detailed information about system requirements, installing VMM, upgrading or migrating from a previous version, and additional deployment and configuration information.
    2. Virtual Machine Manager Guide to Operations Manager Integration: This guide provides information essential for the successful integration of System Center Operations Manager 2007 with Service Pack 1 (SP1) or Operations Manager 2007 R2 with System Center Virtual Machine Manager (VMM) 2008 or VMM 2008 R2. The topics in this guide provide system and security requirements, detailed procedures for performing a successful integration, and troubleshooting for integration issues, whether you are a new VMM customer or you previously integrated Operations Manager with VMM 2008 or VMM 2008 R2 Beta. Procedures also are provided for enabling Performance and Resource Optimization (PRO) and configuring reporting in VMM. A successful Operations Manager integration is a prerequisite for both the PRO and reporting configurations.
    3. Virtual Machine Manager Security Guide:  This guide provides the information needed to successfully configure security for VMM 2008 and VMM 2008 R2. Topics include security basics (role-based security, ports and protocols used by VMM, and account requirements for administrative tasks); instructions for hardening the VMM server, database server, virtual machine hosts, library servers, and self-service Web servers against unauthorized access; domain and account requirements for integrating System Center Operations Manager 2007 with VMM; and security requirements for managing a VMware environment by using VMM.
    4. Virtual Machine Manager Operations Guide: This guide provides information essential for the successful configuration of VMM 2008 and VMM 2008 R2. For new customers, this guide explains how to configure the required and optional features of VMM after setup. The guide also provides information about creating, managing, and migrating virtual machines; performing maintenance on virtual machines, their hosts, and the VMM server; and managing a VMware Infrastructure 3 (VI3) environment by using VMM.
    5. Virtual Machine Manager Scripting Guide: This guide provides an overview of the Windows PowerShell – Virtual Machine Manager command shell and sample scripts that explain how to use Windows PowerShell scripting to manage your virtual system infrastructure.

  • Microsoft Virtualization: Running Linux on Hyper V R2




    Message from Microsoft Virtualization Team


    It is our endeavor to provide our customers who have Windows and non-Windows guests an enterprise class virtualization platform. Towards that end we support running Linux (SUSE Linux Enterprise Server and Red Hat Enterprise Linux) on Hyper-V and provide integration components for these operating systems. This allows our customers to run these OS’ in an optimized manner on Hyper-V. In addition, to ensure that customers have an integrated experience, we also submitted our Linux IC’s into the Linux Kernel so distributions in the future will have the Linux IC’s built-in. 

    It is also our endeavor to provide our customer with the tools and guidance on running Linux on Hyper-V. There have been many (MS and other) blogs about the process of installing Linux on Hyper-V, as well as some recorded demos. However, not many of these came from a Microsoft spokesperson.

    This year, Platform Strategy team has taken upon themselves to develop and deliver content for Linux on Hyper-V, as well as high quality screencasts. The first one in the series is for installing SLES 10.2 on Windows Server 2008 R2 Hyper-V, enabling the integration components, as well as mouse control.

    You can watch this screencast from Shai Ofek, Lead Technical Product Manager, Microsoft Corp.

    Virtualized SLES 10.2 on Hyper-V v2: http://www.screencast.com/t/MmNhMWZlM2

    In July we notified you of Microsoft’s contribution to the Linux kernel, and the release of v2 Integration Components.

    Since then we informed you of the support agreement we formed with Novell for SUSE Linux Enterprise Server 10.2, and have worked a similar agreement with Red Hat for Red Hat Enterprise Linux 5.3 and 5.4.
