root\virtualization\v2 ExportSystemDefinition AVHDX

Question

I use root\virtualization\v2 ExportSystemDefinition , I only want to export the disk configuration file, if I do not choose to export the disk, it will generate AVHDX files, I cannot delete them
https://learn.microsoft.com/zh-cn/windows/win32/hyperv_v2/exporting-the-configuration-of-a-virtual-machine
That's my choice
exportSettingData["CopySnapshotConfiguration"] = 1;
exportSettingData["CopyVmRuntimeInformation"] = false;
exportSettingData["CopyVmStorage"] = false;
exportSettingData["CreateVmExportSubdirectory"] = true;
exportSettingData["CaptureLiveState"] = 0;
I can get the configuration file for it, but it will have an AVHDX file in the disk directory

i need help,What should I do

Answer 1

Hi Richeal,
Generally speaking，to export the vmcx file is like to take a snapshot of the vm at the moment you took the action. The vmcx file you get would be the configuration information at that certain point. Thus，there would be data difference，so that the avhdx file would be created in case you want to restore the vm to that certain point.

Thanks for your understanding.
Best Regards,
Danny
