What’s New in Hyper-V

On 20 December 2012 by Pete Petersen


After reviewing the new features of Windows Server 2012, some of the most interesting in the space of virtualizing the user experience are:

  • Hyper-V
    • Storage Migration. “Move the virtual hard disks used by a virtual machine to different physical storage while the virtual machine remains running.” This is a big deal. This means that for implementations of smaller environments that the need for shared storage (a SAN) is much reduced.
    • Storage on SMB 3.0 File Shares. “Hyper-V now supports use of SMB 3.0 file shares to provide storage for virtual machines.” Wow. Another great feature for smaller implementations, further reducing the need for SAN-level equipment.
    • Hyper-V Replica. “This feature enables you to replicate virtual machines between storage systems, clusters, and data centers in two sites to provide business continuity and disaster recovery.” Similar to Storage Migration, this is a huge deal for those organizations that need to move VMs live and makes the maintenance of these VMs much easier.
    • Client Hyper-V. “The Hyper-V technology is now available in a desktop operating system version of Windows.” As written in a previous post, this essentially precludes the need for XenClient or VMware Workstation.
    • Resource Metering. “You can now track and gather data about physical processor, memory, storage, and network usage by specific virtual machines.” Another great troubleshooting and performance monitoring tool that will be a welcome blessing to many an administrator.

It will be helpful to read through them all, but that gives you a flavor of some of the new things.
