proxmox qmp command blockdev-snapshot-delete-internal-sync failed

While trying to move a VM from one node to another I got the error message:

VM 100 qmp command ‘blockdev-snapshot-delete-internal-sync’ failed – Failed to get a snapshot list: Operation not supported

One snapshot was stuck and the VM locked. How to solve this?

qm unlock 100
qm listsnapshot 100
qm delsnapshot 100 preFirstBoot --force
qm unlock <ID>
qm listsnapshot <ID>
qm delsnapshot <ID> <snapname> --force

it might be that the snapshot will remain on the hard disk.

Happy unlocking :)
