I've tested the following (now mainly through the UI) again:

- creating a VM with tpmstate0 with raw/qcow2 format
- moving a VM with tpmstate0 with qcow2 format between storages
- converting existing VM from raw to qcow2 format and vice versa
- cloning VMs to the same storage again
- starting any of those (debian13 and win11) worked fine
- `kill -KILL $(pidof qemu-storage-daemon)` and starting the VM again
  afterwards cleaned up as expected

I've checked the commits without R-b and diffed the new code changes
against the v1 and grepped for changes from vmid to id and whether all
*_cmd(...) calls have the right arguments with the new name field.

Looks good to me, consider this:
