Error Importing Hyper-V VM (The Virtual Machine Is Using Processor-Specific-Features)

I am trying to move a Windows 10 VM from an older Windows 10 PC to a more recent one. I am not doing a Live migration. I exported the VM on the older box and copied the resultant folder to the newer PC. When I start the import, I get an error that says...

"The virtual machine [NAME] is using processor-specific-features not supported on physical computer [NAME]. To allow for migration of this virtual machine to physical computers with different processors, modify the virtual machine settings to limit the processor feature used by the virtual machine."

I have three saved states and this error is repeated for the other two states as well. It gives me an option to delete the saved states or cancel. I enabled the CPU compatibility option for the VM and then re-exported and imported but it doesn't help. Anyone know how to fix this?

    Hi,

    To change the compatibility settings, we need to shut down the viutual machine (in a saved state, the settings is grayed out) and then tick the checkbox. After that, we can export and import to see if it works.

    Hello Alex. thanks for the reply. As stated in my post, I enabled the CPU compatibility option but it did not help.

    Hi,

    Thank you very much for the clarification. Are you export/import from Intel processor to AMD processor, or vice versa? It is not supported to export/import betwween processors of different vendor. If different vendor, we can copy the .vhdx file and re-create in the new hyper-v host.

    Also, I want to add that I was able to successfully bring over a Windows 7 VM without this issue. It's the Windows 10 VM that is the problem.

    Thanks Alex. Both devices have Intel processors. Weird that the Windows 7 VM doesn't give me a problem.
