Hi Salam

Thank you for contacting the Microsoft Community!

We can try these steps to help you export HyperV VM：

Verify the folder permissions and location

Try to export after turning off the machine

“You can do this on a virtual machine that is in either a started or stopped state.”

https://learn.microsoft.com/en-us/windows-server/virtualization/hyper-v/deploy/export-and-import-virtual-machines?tabs=hyper-v-manager

Verify the folder permissions and location

Use a local export folder: Do not use network sharing or the export path you used before. Instead, create a new folder on your local drive (for example, C:\HyperVExport), and ensure that both your administrator account and SYSTEM account have full control over it.

There are no pre-existing conflicts: Ensure that there are no existing export folders or residual contents from previous attempts to export that might lock certain files.

Test through PowerShell

Export using PowerShell: Don't rely solely on the Hyper-V manager UI. Try exporting through PowerShell:

Export-VM -Name "YourVMName" -Path "C:\HyperVExport"

Wish you all the best！

Best Regards,

Andrew

Hi Andrew,

VMs are turned off

What is meant by permission and location for the folder. I have an H drive where I have he structure as follows

The highlighted folder contains all VHDX.

Regarding permissions on the Hyper-V and child folder Virtual Hard Disks , my user is the owner of those folders.

I tried

Export-VM -Name "myVM" -Path "M:\hyperVToTransfer"

I got

Export-VM: Export failed for virtual machine 'myVM'. Export failed for virtual machine 'myVM' (6BB0907C-A8A3-4AF8-B4F2-4C57DB14A2A1) with error 'Access is denied.' (0x80070005).

I am not able to understand "Access denied" to what.

Hi Salam

Based on your screenshot of the error report, it seems that the problem lies in the permission issue of your Hyper-V folder and child folder Virtual Hard Disks.

Besides the owner permission of the user, additional permissions need to be added here the permissions of Hyper-V Host.

Wish you all the best！

Andrew

Hi Salam

Could you please adding this permission at the source location（H：\Hyper-v） as well?

In addition, you can refer to the following link:

https://learn.microsoft.com/en-us/answers/questions/813169/export-import-vm-on-hyper-v-with-error-general-acc

https://learn.microsoft.com/en-us/archive/msdn-technet-forums/30bbc245-4170-44e9-8c96-0c9239a4e61c

If it still cannot be exported, please provide a screenshot of the GUI, thank you!

Best Regards,

Andrew

Andrew, since I changed the owner of the folders to my users, each time I reboot my winows 10 it becomes very slow, when I check processes, I see RAM spikes to 98%, I trigger Hyper-V console, It tried to start all VMs which consumes all RAM in addition to strange behavior of VMs get stuck in stopping state
