MED-V

MED-V or Microsoft Enterprise Desktop Virtualization is like SUPER XP mode 🙂

As great as XP Mode is, it has caused a few problems where people are now wondering if MED-V has been replaced-it hasn’t.

First up-MED-V is used for virtualizing legacy applications so they can be run on new OS’s like Vista and Windows 7. Yes that sounds a lot like XP Mode but MED-V introduces a whole extra management layer for use in the corporate world-specifically:

“MED-V provides important centralized management, policy-based provisioning and virtual image delivery to reduce the cost of Virtual PC deployment”

Stephen L Rose has got a great post over on the Windows Team Blog about the differences between these 2 technologies so, rather than re-invent the wheel I’m going to respectfully copy & paste 😉

How does MED-V adds management to Windows Virtual PC?

To provide a managed, scalable solution for running virtual Windows XP applications, MED-V addresses many of the IT challenges around deployment and management including:

  • Deployment – deliver virtual Windows images and customize per user and device settings
    • Automate first-time virtual PC setup based on an IT customized script – including assignment of a unique computer name, joining to AD domain
      (for instance: assign the virtual PC a name that is derived from the physical device name or the username to simplify identification and management)
    • Adjust virtual PC memory allocation based on available RAM on host, so that the virtual PC does not take significant resources from the user
  • Provisioning – define which applications and websites are available to different users
    • Assign virtual PC images according to users and groups
    • Define which Windows XP applications will be available to the user through the start menu
    • Define which websites (e.g. internal sites that requires a previous version of Internet Explorer) are redirected automatically to Windows XP
  • Control – assign and expire usage permissions and Virtual PC settings
    • Control the network settings of the Virtual PC (e.g. whether it connects through NAT or DHCP, whether its DNS is synchronized with host)
    • Authenticate user before granting access to the Virtual PC
    • Set expiration date, after which the Virtual PC is not accessible to the end user
  • Maintenance and Support – update images, monitor users and remotely troubleshoot
    • Update images using TrimTransfer network image delivery – update a master Virtual PC image, and MED-V will automatically distribute and apply the changes to all endpoints
    • Centralized database aggregates events from all users, and provides troubleshooting information on malfunctioning virtual PCs
    • Administrator diagnostics mode allows faster resolution of Virtual PC issues
    • Run on multiple platforms – MED-V will work on both Windows 7 and Windows Vista, and will not require processor-based virtualization support

MED-V is available only as part of MDOP and thus is only available to certain volume licence customers with active Software Assurance.

This technology builds on Microsoft Virtual PC and the new version has got some great new features including:

USB Support: Access USB devices connected to your Windows 7 machine directly from the Virtual Machine.

Clip Board Sharing: Copy and paste between your Windows 7 desktop and your Virtual desktop.

Printer Redirection: Print directly from your Virtual PC.
