Hey guys,

I'm trying to migrate my Windows 11 VM from my cache pool (mnt/cache/domains/Windows 11/) to a dedicated VM storage pool (mnt/vdiskpool/domains/Windows 11/). I transferred the 'domains' share to the 'vdiskpool' drive, ran mover, and then made sure there's no secondary drive for the domains share. The VM works fine until I realized that 'vdisk1.qcow2' was still located in mnt/cache/domains/Windows 11. So I tried to transfer the .qcow2 file from the cache drive to the vdiskpool drive. When I do, I get this message.



It seems it's expecting for it to be on the cache drive. I've looked within the VM config (even the xml) and I cannot find any line which governs the location of this qcow2 file. At this point I remembered that I created a snapshot for this VM - not for any particular reason, just to see how it works. I don't really know how to delete it.
I asked for help in the official discord server and a user called 'Kilrah' advised that I change the following highlighted lines in the snapshots.db file to /mnt/user/domains/Windows 11/.

but after I did that and rebooted Unraid, I still get the same error. I can confirm that even after all this, copying the vdisk1.qcow2 file to /mnt/cache/domains/Windows 11/ still works flawlessly, meaning something else definitely still expects it to be there.

Here is my VM config:


Would deleting the snapshot somehow help?
Should I revert the changes I made in the snapshot.db file?

How can I fix this?

You can try changing all references to /cache/ on the XML to /vdiskpool/, assuming everything has been moved there.

I've tried this, although the weird thing is that when viewing the XML while the VM is running, it DOES make mention to the cache directory where the qcow2 file is located. However, I cannot make change to it while it's running.
But when I shut down the VM, and again try to view the XML - the reference to the directory is gone! It simply doesn't exist anymore!

Here is the XML when the VM is shut down:
