I have a VM running Windows Server 2008 R2 previously hosted on a Windows Server 2012 R2 Hyper-V host. Eventually exported prior then imported after the host was upgraded to Windows Server 2016.
Unfortunately, we can no longer delete any checkpoint of the VM with the error message, "The operation failed because the file was not found."
There are event logs recorded by "Microsoft-Windows-Hyper-V-VMMS-Admin" in Event Viewer and here are the Event IDs: 14026, 20924, 20864, 14320, 15070, which basically looking for a differencing disk.
Running the following command indicate that there are a few VM Snapshots with missing ParentCheckpointName of and ParentCheckpointId.
"Get-VMSnapshot -VMName TEST-VM | format-table name, ParentCheckpointName, id, ParentCheckpointId"
I tried creating the missing AVHDX file using the filename indicated by the event logs and used VHD Inspect to make sure parent AVHDX file exists but when I try to delete the checkpoint, Hyper-V Manager looks for another AVHDX file and the first one created is deleted automatically.
Can you please help.
