This continues on from last week's post to show the changes needed to enable the "slipstreamed" Hyper-V RTM role at the time of operating system deployment. To start with, follow the steps from part 1 to add KB950050 to each of the images in the WIM file for Windows Server 2008. Then create an unattended installation file: Open Windows System Image Manager from the AIK tools to open the WIM file from Windows Server 2008 x64. When asked, select the appropriate image in the WIM and generate a catalog file.
Then in the Answer File area, create a new answer file:
In the Windows Image area, verify you have KB950050 present under "Update":
Select the Foundation Package in the Answer File.
Examine the properties in the top right pane. Scan down to Windows Features Selections and toggle Microsoft-Hyper-V and Microsoft-Hyper-V-Management-Clients to Enabled. (If preparing an answer file for server core, just toggle Microsoft-Hyper-V).
Now close the answer file by right-clicking at the top-most node in the Answer File tree view and save the file to disk. (Of course, you can use an existing answer file which has additional configuration already put in place).
If you take a peek at the XML file which is created, in the unattend\servicing section, you’ll notice the selections for Hyper-V (This is the XML for a full installation. For server core, Microsoft Hyper-V Management Clients should not be present).
Now to add the image(s) from the WIM to WDS and allow unattended installation using the answer file we just created. I happened to give it a “Root:” prefix to distinguish it from the other images I deploy to virtual machines. Once added, right click and select properties. Check the “Allow image to install in unattended mode”.
Click Select File to browse to the XML file you created. And that’s pretty much it. Just PXE boot a server and the Hyper-V RTM role will be present and enabled when installation completes.
