I have a linked clone VM that I want to clone to another VM but this fails. Any work arounds?

I am pretty sure this has soemthing to do with the EFI/TPM disks Win11 requires. They show as qcows2 but are actually raw

TASK ERROR: clone failed: copy failed: command '/usr/bin/qemu-img convert -p -n -f qcow2 -O raw /mnt/pve/pvevm/images/120/vm-120-disk-2.qcow2 zeroinit:/mnt/pve/pvevm/images/367/vm-367-disk-0.raw' failed: exit code 1

yes, there was a bug over a year ago, where you could wrongly end up with a TPM drive with a qcow2 extension: https://git.proxmox.com/?p=qemu-server.git;a=commit;h=5f5aba2578e117247ec8ae5fcd925d3e19cba5c0 But the EFI disk can be qcow2, that's supported and not an issue.

Is /mnt/pve/pvevm/images/120/vm-120-disk-2.qcow2 the TPM disk? Best to have a tested backup before attempting it, but it might be enough to just rename it with a .raw extension and update the VM configuration accordingly.

Can you post the output of pveversion -v and qm config 120 --current?
