SYMPTOMS

Consider the following scenario:
  • You have a computer that has Windows Server 2008 installed together with the Hyper-V role.
  • You run Sysprep on the computer to prepare the installation for image capture.
  • You deploy the captured image.
In this scenario, the Hypervisor layer service does not start automatically.

CAUSE

This issue occurs because there is no Sysprep provider for Hyper-V. Therefore, the HypervisorLaunchType BCD entry is removed from the Boot Configuration Data (BCD) file when you run Sysprep.

WORKAROUND

To work around this issue, you must use the Bcdedit tool to add the missing entry to the BCD file. To do this, follow these steps:
  1. On the computer where you deployed the image, open a command prompt.
  2. At the command prompt, move to the following directory:
    %Windir%\System32
  3. Type the following command, and then press ENTER:
    Bcdedit /set {current} hypervisorlaunchtype auto
  4. Restart the computer.
