Milan thanks for the info, I suspected as much.

Yes it's a Windows 11 VM, so TPM is locked in the on position while Windows 11 
OS selected.

I'll keep an eye on the bug and see if I can work around it for now.

I suspect it will be problem if using the TPM for something like bitlocker, 
potentially losing the TPM data will mean having to enter the decryption key 
manually at boot and re-provision the TPM on restore.

Thanks again for taking the time to reply and filing a bug.

it is a Windows VM, right?  It is a bug, I filed .  The export should work.

A workaround could be temporarily switching the VM operating system in the VM 
properties to Red Hat Enterprise Linux 9 before exporting but I'm not sure it 
won't change some other VM properties, be careful if you attempt it.
