I can't start a VM (any) on my Win 8 laptop. I tried re-installation of hyper-v with no success (uninstalled Hyper-V and checked with VMWare Player and it works, so it's not a hardware issue, I guess).

do you have VMware player installed on your system when you try to start Hyper-V? – AbhishekGirish Mar 8 '13 at 20:17
Hyper-V requires specific hardware support does your hardware meet those requirements? The requirements are also well documented. – Ramhound Mar 8 '13 at 20:53
you have any more information, like the behaviour or error messages. "it doesn't work" is vague. – BroScience Mar 8 '13 at 21:49
Check the system event log - you'll see messages about Hyper-v or the hypervisor etc., not starting, and why. – Mark Allen Mar 9 '13 at 4:42
AbhishekGirish - I uninstalled it before installing hyper-v again. Only hyper-v is installed now. Ramhound - I have a brand new laptop with the latest i5 - hyper-v is supported. BroScience and Mark - this is the message: 'New Virtual Machine2' could not initialize.

Here are requirements for Hyper-V :

  1. Hyper-V is 64-bit only and thus requires a 64-bit (x64) processor
  2. Hardware Virtualization Assists in the form of: Intel VT-x / AMD AMD-V
  3. Hyper-V requires Hardware Data Execution Prevention :

Set these BIOS options to enable:

  • On Intel processors this is called Execute Disable (XD).
  • On AMD processors this is called No Execute (NX).

Set these BIOS options to disable:

  • Intel VT-d (AMD-V) is disabled
  • Trusted Execution is disabled

Here are concise instructions needed to run Hyper-V. Please check it, it is very helpful in setting up Hyper-V.


Hyper-V Platform is available on Professional & Enterprise editions of Windows 8 only.

I followed the manual with no success (vt-d indeed needed to be disabled and I reinstalled hyper-v). Any other good idea? – Uri Mar 9 '13 at 19:11
my laptop started as standard version of windows 8 and after that I upgraded to professional edition. do you know if there's some other service that should also be enabled for the hyper-v to work? – Uri Mar 14 '13 at 20:33
In Control Panel -> Uninstall Programs -> (Left-side panel)Turn Windows Features On or Off -> Tick Hyper-V – user568109 Mar 15 '13 at 4:03
already done - the hyper-v manager looks ok but the vm cannot be started. – Uri Mar 15 '13 at 7:54
