Video Series for Application Virtualization

How to configure App-V; create, publish, and update virtual applications; and create and manage policies for virtual applications.

Videos available here

AppLocker is a new feature of Windows7 that allows administrators to define policies that can allow or deny a user’s ability to run or install executable, MSI, or script files. Microsoft Application Virtualization (App-V) separates the application from the operating system preventing application conflicts and enabling the ability to run multiple versions of an application of the same desktop. Virtual applications can be delivered in many ways – streaming by assigning applications to user, delivering to machines via Configuration Manager or by using file streaming from removable media. Using App-V and Applocker together ensures that no matter how the application is delivered or what format is takes, physical or virtual, it will respect the policies defined by IT. Watch these demonstrations to learn how to configure App-V; create, update, and publish virtual applications; and create and manage policies for virtual applications.

    Troubleshooting alert storms in SCOM 2007

    leave a comment »

    From System Center Operations Manager Team;

    A large and sudden increase in the number of alerts is called an alert storm. An alert storm can be a symptom of massive changes of some kind within your management group, such as the catastrophic failure of networks. An alert storm can also be a symptom of configuration issues within Microsoft System Center Operations Manager 2007.

    Installing new or updated management packs can give rise to an alert storm. Monitors in a management pack begin working as soon as the management pack has been imported. Use best practices in importing management packs to minimize alert storms.

    Linux P2V – Vmware and Hyper-V

    leave a comment »

    Although you can P2V Windows machines using System Center Virtual Machine Manager, the same functionality is not available for Linux computers (Note:  You can V2V a Linux VM).

    VMware vCenter Converter is a free tool that allows you to convert Linux physical machines into VMs. The process will create a vmdk disk file.  The problem is that it appears that the target must be VMware ESX, ESXi, Workstation or Player.

    If you need to move that machine to Hyper-V, you can, in theory, use a tool like VMDK2VHD to convert that vmdk to a vhd file. If you’re using System Center Virtual Machine Manager to mange VMware vCenter Server you can do a direct V2V from VMWare ESX to Hyper-V hosts. After migration process, you’ll need to install integration components which are supported on RHEL and SLES.

    SCVMM Host Reserve Settings in detail…

    leave a comment »

    Apparently there is a misconception about How SCVMM Host reserve settings work.

     Steve Thomas from System Center Virtual Machine Manager Team, explains the “How Host Reserve Settings Propagate from Host Groups to Individual Hosts in SCVMM

     When you set the properties for “Host Reserves” at the Host Group level in System Center Virtual Machine Manager 2008 or SCVMM 2008 R2, you are, in essence, setting template values for host reserves for newly added hosts only. A common misconception is that when you set these reserves on host groups with active hosts that these reserve values will propagate down automatically or that these hosts will inherit those settings. That is not the case.

    Hyper-V and Red Hat Enterprise

    leave a comment »

    From Windows Virtualization Product Group

    Hyper-V customers are running both SUSE Linux Enterprise Server and Red Hat Enterprise Linux as guests. We have provided Linux integration components for SUSE Linux Enterprise Server, but customers did not have the same level of performance with Red Hat Enterprise Linux as a guest since the IC’s were not supported for RHEL.

     We are excited to announce the availability of Linux integration components for Red Hat Enterprise Linux (RHEL 5.2, 5.3, and 5.4) which provides synthetic network and storage drivers enabling RHEL to work with the optimized devices provided by Hyper-V.  We’ve already submitted these drivers to the upstream Linux kernel in July 2009 (read here for more information) and are looking forward to these being integrated with a future version of RHEL.  In the meantime, Microsoft will provide full support for these drivers.  Red Hat provides best effort support for these components. Customers interested in understanding how these are supported by Red Hat prior to their inclusion natively into to their distribution can read the details at the Red Hat Knowledge Base article.

     To download this new version of the Linux Integration Components, visit this link on the Microsoft Download Center.
