SCVMM 2008 R2 Problem with P2V from Dell Physical Server

Had a client that I upgraded to 2008 R2 Hyper-V and SCVMM 2008 R2. When they tried to P2V Dell Physical servers they received BSOD or errors on the Install Integration Services step. We tried over and over and could not successfully P2V the server. We then tested to see if a new VM build had any problems with installing Integration Services, worked perfectly. So we ended up getting Microsoft Premier Support involved. After several tests and trials later the problem was solved; the problem dealt with the physical server being build with the Dell OpenManage startup CD. Seems this method of build set a registry key that conflicts with the Integration Services install. The key in question is:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Wdf01000\Group] = Base
changing the key to "WdfLoadGroup" and rebooting the VM allowed the Integration Services to install successfully.
