BindToHostTPM error in Hyper-V Manager Win 10 1803 RRS feed

  • Question

  • Does 1803 break compatibility with Windows Server 2016?

    How can I fix this?

    On my technician computer, the settings in virtual machine \ settings \ hardware \ security have become unavailable for all gen 2 vms on all Hyper-V servers. It reads ‘Load Failed” as well as “Property ‘BindToHostTPM’ does not exist in class ‘Msvm_SecuritySettingData’.

    This error makes sense, since it does’t exist in Msvm_SecuritySettingData

    class Msvm_SecuritySettingData : CIM_SettingData{

    boolean TpmEnabled;
      boolean KsdEnabled;
      boolean ShieldingRequested;
      boolean DataProtectionRequested;
      boolean EncryptStateAndVmMigrationTraffic;
      boolean VirtualizationBasedSecurityOptOut;

    Hyper-V Manager: Windows 10 1803, build 17134.112

    Hyper-V Server: Hyper-V Server 2016 build 14393

  • Hi,

    Thanks for your question.

    I have done some research for this symptom, Please refer to the link:

    A shielded VM can start on a host device after the device can attest its health to the correct HGS server. To further secure the VM, ensure only the owner of the VM can start it, we added a policy to lock the shielded VM on the device where it is created. This is a policy controlled by the administrator, the setting is stored in the shielding data file, and it will be enforced at the shielded VM creation time.

    New-ShieldingDataFile [-ShieldingDataFilePath] <string> [-Owner] <Guardian> [-VolumeIDQualifier] <VolumeIDQualifier[]> [-AnswerFile] <NamedFileContent> [[-OtherFile] <NamedFileContent[]>] [[-Guardian] <Guardian[]>] [-Policy {Shielded | EncryptionSupported}]  [-BindToHostTpm <bool>] [-WhatIf] [-Confirm]  [<CommonParameters>] 

    By setting the BindToHostTpm to true, the shielded VM will only start on the device where it is created. This is to prevent a case where an insider tries to steal a shielded VM and attempts to get it started on a different PAW device.

    We can see the shielded VM can start by retrieving the parameter BindToHostTpm, however, it can’t find it from the shielding data file. It may be a known issue.

    Based on the specific situation, we suggest you try to start the shielded VM from the Hyper-V server locally to see if it works.

    Hope this helps. If you have any question and concern, please feel free to let me know.

  • Thanks for finding this but I don't see how this applies to my configuration because all I have is plain regular config 8.0 gen 2 VMs.

    There is no PAW devices or shielded VMs or any of that. I shouldn't have this error, right?

  • I have this problem too. Windows 2016 Datacenter with Gen2 Windows 10 1803 VM.

    I running Hyper-V Manager on Windows 10 1803 and connecting to VM on Server 2016. 

    I see same error. If I open settings for VM directly on Server 2016, no problem.

    VM not shielded, even secure boot turned off.

  • I'm also seeing this with windows 2016 server, just needed to turn off secure boot via PS to install a new VM.  This seems to be yet another bug from Microsoft with the last updates.

  • Hello. I have the same problem and still cant find any answer how to resolve it, except of reinstalling the hyper-v which is not quite acceptable.

    Did anyone solve the problem yet?

    thank you
