Windows 8 Will Come with Hyper-V, Microsoft Confirms

In another post at Building Windows 8 blog, Microsoft has confirmed that Hyper-V will be a part of Windows 8.

Here is what the official post says:

In this post we talk about how we will support virtualization on the Windows "client" OS. Originally released for Windows Server where the technology has proven very popular and successful, we wanted to bring virtualization to a core set of scenarios for professionals using Windows.

In building Windows 8 we worked to enable Hyper-V, the machine virtualization technology that has been part of the last 2 releases of Windows Server, to function on the client OS as well. In brief, Hyper-V lets you run more than one 32-bit or 64-bit x86 operating system at the same time on the same computer. Instead of working directly with the computer's hardware, the operating systems run inside of a virtual machine (VM).

By default, Hyper-V would not be enabled in Windows 8 and you'll need to enable Hyper-V using "Control Panel -> Programs and Features -> Turn Windows features on or off".


An introduction to Hyper-V:

Hyper-V requires a 64-bit system that has Second Level Address Translation (SLAT). SLAT is a feature present in the current generation of 64-bit processors by Intel & AMD. You'll also need a 64-bit version of Windows 8, and at least 4GB of RAM. Hyper-V does support creation of both 32-bit and 64-bit operating systems in the VMs.

Hyper-V's dynamic memory allows memory needed by the VM to be allocated and de-allocated dynamically (you specify a minimum and maximum) and share unused memory between VMs. You can run 3 or 4 VMs on a machine that has 4GB of RAM but you will need more RAM for 5 or more VMs. On the other end of the spectrum, you can also create large VMs with 32 processors and 512GB RAM.

As for user experience with VMs, Windows provides two mechanisms to peek into the Virtual Machine: the VM Console and the Remote Desktop Connection.

Another great feature of Hyper-V is the ability to take snapshots of a virtual machine while it is running. A snapshot saves everything about the virtual machine allowing you to go back to a previous point in time in the life of a VM, and is a great tool when trying to debug tricky problems. At the same time, Hyper-V virtual machines have all of the manageability benefits of Windows. Windows Update can patch Hyper-V components, so you don't need to set up additional maintenance processes. And Windows has all the same inherent capabilities with Hyper-V installed.

Having said this, using virtualization has its limitations. Features or applications that depend on specific hardware will not work well in a VM. For example, Windows BitLocker and Measured Boot, which rely on TPM (Trusted Platform Module), might not function properly in a VM, and games or applications that require processing with GPUs (without providing software fallback) might not work well either.

As a reminder, you will still need to license any operating systems you use in the VMs.

  • Nice post VG! anyway are there any other hardware requirements required to run Hyper-V besides having what u wrote above? like what Win8 edition is required? i remembered last time in Win7 for WinVirtual PC requires Win7 Pro or above and a couple of additional hardware requirements... idk if Win8 Hyper-V also needs it too...

  • VG

    ^^ Thats not clear atm.

  • I know that Hyper-V isn't new, but will this replace Windows Virtual PC?

  • @Kyle

    Windows Virtual PC will work on any edition of Windows 7, it's Windows XP Mode that required Windows 7 Professional or higher.

  • Seriously MS needs some good designers to work on it's 'Metro' inspired theme... looks ugly... Vista was beautiful... 7 was OK... 8 looks ugly...

  • I totally agree you Samar, i never actually liked Vista, it was slow and it eats memory so much, but i love Windows 7 very much, it's lightweight and very beautiful! But i hate w8 so much, i hate those panels and i hate its interface so much, i'm not gonna install w8 ever!!

    And one more thing: w8 looks very very very slow!

  • @TheAslan
    If 8 is anything like i would definitely go for it... but till now MS has it seems not hired designers for 8
