ok, I think it could be possible to use blockdev-reopen to rename
current filename
https://lists.gnu.org/archive/html/qemu-devel/2021-05/msg04455.html
example: take snapshot : snap1 on vm-disk-100-disk-0.qcow2
- create a hardlink: ln vm-disk-100-disk-0.qcow2 vm-disk-100-disk-0-
snap1.qcow2
- qmp blockdev-reopen file vm-disk-100-disk-0-snap1.qcow2
- rm vm-disk-100-disk-0.qcow2
- create a snapshot with a new file vm-disk-100-disk-0.qcow2 with vm-
disk-100-disk-0-snap1.qcow2 as backing file
I'll try to test this tomorrow !
