Hyper-V host blue screens (BSOD) after being added to SCVMM

February 26, 2018 Leave a comment


When rebooting a Hyper-V host running on VMware Workstation after adding it to System Center Virtual Machine Manager (SCVMM), the host will not boot & blue screens (BSOD).


When a Hyper-V host is added to SCVMM, several hardware IDs are added to the Multi path I/O (MPIO) list. One of these hardware IDs are not compatible on VMware Workstation.

To see a list of hardware IDs added by SCVMM run:


It’s worth noting that when the MPIO role is installed, the only ID in the list is a generic entry for Vendor 8 Product 16.


Boot the Hyper-V host to the last known good configuration. Once it’s back up, add the Hyper-V host to SCVMM again. Before rebooting, remove the MPIO entry for MSFT2011SASBusType_0xA by running the following PowerShell command:

Remove-MSDSMSupportedHW -VendorId "MSFT2011" -ProductId "SASBusType_0xA"

Now reboot the Hyper-V host.



Errors Installing Windows Server 2012 R2 in a Virtual Machine

September 8, 2014 5 comments

Error #1

When installing Windows Server 2012 R2 on a VM (vSphere or Hyper-V) configured for EFI you may receive the following error when booting to the ISO. “Windows failed to start. A recent hardware or software change might be the cause. To fix the problem… File: \EFI\Microsoft\Boot\BCD. Status: 0xc000014c. Info: The boot Configuration Data for your PC is missing or contains errors.”

Error #2

When loading the VMware Paravirtual SCSI driver you receive an error that says, “No new devices drivers were found. Make sure the installation media contains the correct drivers, and then click OK.”

error on clean install won't load driver


Error #3

The installation cannot load any SCSI driver & says, “A media driver your computer needs is missing.”

Error #4

“No device drivers were found. Make sure that the installation media contains the correct drivers, and then click OK.”



Cause – Corrupted ISO

Solution – Re-download the ISO & try again. In my experience ISOs can become corrupt if you pause them when downloading.

Hyper-V Host Can’t Get to the Internet

The Configuration

Windows 8.1 Pro with the Hyper-V Role installed. One physical NIC with a static IP address.

1 static ip

Configure an External Virtual Switch bound to the physical adapter.

2 virtual switch

The Problem

Virtual machines can get to the Internet just fine but the Hyper-V server cannot.

3 no internet

Hyper-V server can’t even ping Bing.

4 no bing ping

Hmmmm…can’t even resolve Looking at the IPv4 properties of the vEthernet (External) NIC there is no DNS configured.

5 no dns

The Solution

Add the IP of the router (or whatever DNS server you use) back in for the DNS server(s). Now the Hyper-V server can access the Internet.

The Cause

When creating the External Virtual Switch a dialog box popped up that said, “Pending changes may disrupt network connectivity. This computer may loose blah, blah, blah”. But then it says, “These changes also may overwrite some static changes. If that happens, you must reapply the static changes to restore network connectivity.”

6 apply network changes

So there you go. When configuring Hyper-V to use a NIC that has a static IP configured you may loose some or all of it when it moves those settings to the vEthernet NIC.
