Windows 10: Windows 10 Hyper-V VM Failing to update to 20H2 pushed out via SCCM

We have a few VM's running on 1909 that we are trying to upgrade to 20H2, pushing it out via SCCM, however the install keeps failing. Sometime's the updates installs, but then when rebooting to apply the updates it gets rolled back. Checking the update logs, I've noticed multiple error messages, 800703F1 and 80041010.Any advice to help troubleshoot this would be appreciated.Thanks,Luke

Export Win10 Hyper-V VM and import into Server 2016

I am having trouble moving a VM from windows 10 to Server 2016. I have updated Win 10 to 20H2 and applied all available windows updates. I created a VM on Win 10, exported it, and then copied to a server 2016 computer with Hyper-V installed but it does
not present as available for import. Is there any way to make this work?

 

Hyper-V Broken after Feature Update

Hello,

Last night the "Feature Update" for Windows 10 installed on my workstation (while I was asleep) and this morning after the reboot, most of my Hyper-V VMs are no longer appearing in Hyper-V manager.

I've done some research and tried a number of different thing suggested on various forum posts and I can't seem to get even a fraction of my VM's back up and running again.

It looks like a reboot was forced without shutting down the VM's first which has somehow corrupted my environment. I'm seeing unusual behaviour such as:

a) I can re-import some VMs back into Hyper-V and they run fine.

b) Other VMs fail to import.

c) Some VMs import successfully but fail to start.

d) Most unusually, some VMs import successfully but after importing they are not shown in the list and they cause other completely separate VMs being removed from the list.

Has this update not only destroyed my machine but half of the virtual machines I've got running on it? Any advice on what I can do to recover?

Regards,

Keith

Hyper-V PowerShell module fails to create new vm

I have a problem with Hyper-V PowerShell module, it fails to create a New-VM on my machine.

It worked fine until I had to reinstall Hyper-V feature in Windows 10.

Since then cannot create VM with powershell cmdlets, creating a VM in GUI works

I receive the following error

New-VM : Hyper-V encountered an error trying to access an object on computer ...... because the object was not

found. The object might have been deleted, or you might not have permission to perform the task. Verify that the

Virtual Machine Management service on the computer is running. If the service is running, try to perform the task again

by using Run as Administrator.

I am the Administrator on local PC, and I checked Hyper-V Virtual Machine Management service, and it is in a running state.

Tried to rebuild MOF file

MOFCOMP %SYSTEMROOT%\System32\WindowsVirtualization.V2.mof

also tried to uninstall Hyper-V feature and reinstall it with powershell, and still no success.

Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All

Any other ideas?

I have Windows 10 Pro, version 1709
