There are other commands for snapshots and backup which are issued via

It might even make sense to make the tcmu interface available at
run-time in QEMU like the run-time NBD server. This allows you to get
at read-only point-in-time snapshots while the guest is accessing the
disk. See the nbd-server-start command in qapi/block.json.

I hope we didn't scaried you with our monster block backend and it's
associated QMP socket ;)
Hi Benoît,
No, I've gone off to work on a initial proof-of-concept implementation
of a qemu-lio-tcmu.so module, hopefully it'll be ready to look at
shortly and then we can shoot arrows at it. :)
But in the meantime, do you have a use case or user story for the QMP
support that might help me understand better how it might all fit together?
Regards -- Andy
