Recently we purchased a machine which support Hyper-V. Ensured with intel on the support of the processor and mother board.

Our server has the below configuration and with win 2008 R2 Hyper-v Server installed.

1. INTEL XEON 1220 PROCESSOR &

2. INTEL BTS MOTHERBOARD

3. 16 GB DDR3 RAM

4. 2Nos TB SATA Hard Disk Drive

5. Server Cabinet with 400 W Power Supply ( Prime Source )

After we have installed the Windows 2008 R2 hyper-v server, we tried to create VMs via the Hyper manager client tool.

Ensured the hyper -v server has installed with latest updates and settings.  Created a VM and tried to launch it where got th error  with below message.

Error.: While launching the  Hyper-v Machine it fails with an error of  An error occurred while attempting to start the selected Virtual Machine

Virtual machine Id D714DA9E-C429-4F85-B17B-9F967796250A

RESOLUTION

We installed the KB 2517374 using WUSA command line and rebooted the server. Able to install the VM successfully.
