Image to Virtual Hard Disk (WIM2VHD) Converter

leave a comment »

You can use WIM2VHD to quickly create a VHD from a WIM file, e.g. the install.wim file in the Vista/Windows7/Server 2008/Server 2008 R2 installation media, and then attach that VHD to a Hyper-V virtual machine.

Mikael Nystrom blogged about WIM2VHD.

Sometimes you need a fast way to create a reference image. You know, suddenly you need to have a VHD file of Windows Server 2008 R2 and a Windows 7 machine, like NOW. It always seem to be NOW or yesterday that things need to be done, wonder why…

Anyway, you need the following:

WAIK (Well, you only need Imagex, but if you have WAIK installed you have that)
WIM2VHD, and that’s just a small download
The OS (You only need the Install.wim, but I’ll guess you already have the DVD somewhere anyway)
This tools i really nice actually, but it only supports Windows 7 and Windows Server 2008 R2. The command line to create a VHD file is quite simple:

cscript WIM2VHD.wsf /wim:g:\sources\install.wim /sku:1

That will create a 40gb dynamic VHD file in less than 3 minutes (Yes, I do have a SSD disk), but it also have a bunch of other commands that could be used to make it more fun 🙂

Required parameters:

  /wim: Path to the .wim file
  /sku: Sku number or sku name

Some Optional parameters:

  /vhd: Name and path to the VHD file you would like to have
  /size: Size (default is 40960 mb)
  /disktype: Dynamic, Fixed or FastFixed (FastFixed requires VHDTOOL)
  /unattend: Path and name of an unattended XML file
  /qfe: A comma-seperated list of .MSU files that you would like to have in the image
  /mergefolder: Names of folders that you would like to have in the image

I use it from time to time when a need a fast solution and i don’t have time to do it the “real” way and in this case the real way is using MDT of course.

Nice work 🙂

KB2264080: Update rollup package for the Hyper-V role in Windows Server 2008 R2

leave a comment »

This article describes an update rollup package that resolves some issues for the Hyper-V role on a computer that is running Windows Server 2008 R2 and that is dated August 24, 2010.

Issue 1
When a computer has one or more Intel CPUs code-named Nehalem installed, you receive the following Stop error message:

0x00000101 ( parameter1 , 0000000000000000, parameter3 , 000000000000000c) CLOCK_WATCHDOG_TIMEOUT
Note The Nehalem CPU for a server is from the Intel Xeon processor 5500 series and for a client computer is from the Intel Core-i processor series.

Issue 2
Consider the following scenario:
You run a virtual machine (VM) on the computer.
You use a network adapter on the VM to access a network.
You establish many concurrent network connections. Or, there is heavy outgoing network traffic.
In this scenario, the network connection on the VM may be lost. Additionally, the network adapter is disabled.

Note You have to restart the VM to recover from this issue.

Issue 3
When a computer has an Intel Westmere processor, you receive an error message that resembles the following:
STOP: 0x0000001a ( Parameter1 , Parameter2 , Parameter3 , Parameter4 ) MEMORY_MANAGEMENT
