Hi Kevin,
Sorry to bother you again.
I intend to use this approach for snapshots of block devices, which, as
you say, requires a lot of disk space to store snapshot data. So, to
save disk space, after each successful external snapshot creation, I
want to shrink the block device that stores

You can either use 'qemu-img commit' to copy all of the data from
diff.qcow2 back into base.im
Hi Kevin,

Hi Kevin,
Thank you for your reply and detailed answers.

Qemu provides powerful snapshot capabilities for different file formats.
But this is limited to the block backend being a file, and support is
