Client Hyper-V in Windows 8


Client Hyper-V is the same computer virtualization technology previously available in Windows Server. In Windows 8 Consumer Preview, the technology is now built into the non-server version of Windows, often called the “desktop” version because it does not run on server-class hardware.
Because Client Hyper-V in Windows 8 Consumer Preview is the same technology as server Hyper-V IT Pros and developers do not need to learn any new tools or commands. You can move virtual machines (VMs) from Client Hyper-V to server Hyper-V. For example, you can build a “test lab” infrastructure hosted entirely on your laptop or desktop machine and export the VMs you create and test from your laptop into production.

Windows PowerShell scripts for managing virtual machines that you create using Client Hyper-V are fully compatible in with Windows Server 8 Hyper-V.

There a few features included in Windows Server 8 Hyper-V that are not included in Client Hyper-V. These include: the remote FX capability to virtualize GPUs (software GPU in RDP 8), Live VM migration, Hyper-V Replica, SR-IOV networking, and synthetic fiber channel.

HARDWARE : Hyper-V requires a 64-bit system that has Second Level Address Translation (SLAT). GB RAM is required. The RAM on your Client Hyper-V machine is allocated and de-allocated dynamically as required by the VMs. You can run several VMs on a Client Hyper-V machine (also called a “host”) that has the minimum 4GB of RAM, but you will need additional RAM for 5 or more VMs, depending on the RAM requirements for each VM.

Client Hyper-V supports server Hyper-V’s “Live Storage Move” capability. This means you can use your VMs fairly independent of the underlying storage. You can move VMs to and from one local drive to another, to a USB stick, or to a remote file share without needing to stop the VM.

To Enable using GUI:

  1. On the Control Panel click “Programs”, and then click “Programs and Features”
  2. Click “Turn Windows features on or off”
  3. Click “Hyper-V”, and then click “OK”, and then click “Close”
To Enable using Powershell :
Enable-WindowsOptionalFeature –FeatureName Microsoft-Hyper-V -Restart

Important :

    You must restart your machine, not just reboot, to complete installation

    What hardware do you suggest for a setup that would use 3 VMs at the same time? Core i3, i5, or i7? Is 6 GB RAM enough?

      Hi, It all depends on the workloads that you plan to run. I currently use an i7 with 8Gb and I am running 6 VM’s
