failed to initialize

I ran into an issue that took me quite a bit of time to resolve that I wanted to share with everyone.  I had a customer that I worked with that was not able to start any VM (virtual machine)  across 3 Hyper-V servers he had deployed in his environment.  When attempting to start the virtual machine it would get to starting…4% and then give a pop-up error message “<VM Name> failed to initialize”.  My first stop was the Hyper-V VMMS log which contained the same error.  I eventually checked the application log and found this event:

Event ID 1000, Application Crash
Faulting application name: vmwp.exe, version: 6.3.9600.18895, time stamp: 0x5a4b1c19
Faulting module name: KERNELBASE.dll, version: 6.3.9600.18895, time stamp: 0x5a4b1cf7
Exception code: 0xe06d7363

Faulting application path: C:\Windows\System32\vmwp.exe
Faulting module path: C:\Windows\system32\KERNELBASE.dll

This led me to a topic referring to an issue with January 2018 windows updates.  You can find that article here.  I uninstalled all updates in January and February on the first server, but this made no difference.  The solution was to change 2 registry keys:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\FeatureSettingsOverride
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization\MinVmVersionForCpuBasedMitigations

Before running the below commands, the values were 3 and 1 respectively.

reg add “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management” /v FeatureSettingsOverride /t REG_DWORD /d 0 /f
reg add “HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization” /v MinVmVersionForCpuBasedMitigations /t REG_SZ /d “1.0” /f

I hope you have found this article informative.  If you have anything to add or just want to comment, please do so below.


How to run Windows Foundation edition as a Hyper-V virtual machine.

I recently needed to reproduce a customer issue in my lab environment.  My lab is a Windows 10 workstation with the Hyper-V role installed.  Part of reproducing the issue involved building out a Windows Server 2012 R2 Foundation virtual machine. I figured this would not be a problem as 2012 R2 runs fine as a virtual machine.  This was not the case though.  I ran into a major hurdle with the integration tools.  I will describe the process I went through to get a Windows Server 2012 R2 Foundation virtual machine running smoothly.

Now before anyone goes out and tries the below procedure for a production system, please understand that running Foundation edition as a virtual machine is not supported by Microsoft.  Also it will likely violate the EULA (End User License Agreement).  Typically Foundation edition is only sold with an OEM license.  That means it comes pre-installed on hardware and must remain on that hardware.  So in order to do this, and not violate the EULA, a non-OEM license is required.  I have a MSDN subscription and thus have a valid license.  Additionally, I am not running the server for any type of production workload.

I started the process by creating a generation 2 VM (virtual machine).  Unfortunately I found out this will not work as the VM bugchecked during setup.  I deleted that VM and created a generation 1 VM.  I was then able to get the Windows loaded.  This is when I discovered the major hurdle I mentioned above.  The VM responded very slowly to mouse and keyboard input.  I also noticed severely degraded performance.  This was to the point of the VM almost being unusable.  The VM behaved as if none of the integration services drivers were installed.  Unfortunately Windows 10/2016 do not have the option to insert the integration disk.  I was able to get the vmguest.iso from a 2012 R2 hyper-v host.  However when I tried to run the setup I was informed that the latest integration services were already installed.

At this point I realized this was not going to be easy, but I enjoy a challenge.  I browsed the vmguest.iso inside the Foundation VM.  I extracted the following file: D:\support\amd64\  I then went into device manager.  I noticed quite a few, a dozen or so, unknown devices.

I then tried to manually load the drivers from the extracted cab file.  While the driver was found, it was not signed.  I figured no sweat, just disable driver signing requirement in the BCD (Boot Configuration Data).  Yet another roadblock.  It is no longer possible to permanently disable driver signature enforcement.  I was able to boot into driver signature enforcement disabled mode.  I then manually loaded drivers for all the Unknown devices.  This corrected the input and performance issues, at least for that boot.  Booting into normal mode caused all the issues to return.


Getting the drivers to load each time Windows booted was the final step in getting the virtual machine to run properly.  I looked into the bcdedit command line options and was not able to find an option to boot to driver signing disabled mode.  What I ended up doing was to add a dummy entry to the boot list and set the timeout to 30 seconds with the following commands.

bcdedit /copy {current} /d "Dummy Entry"
bcdedit /timeout 30



Presently, on each boot I press F8 to get the boot options.  I then select Disable Driver Signature Enforcement.  Now the VM runs with all guest integration services.

If you have been able to find a better way to do this I would like to hear about it in the comments below.
