hi, i want to implement the function of qcow2 resize which has snapshots.
each snapshot of qcow2 will have a separate total size, and when apply a
snapshot,
the image can be shrunk, and the total size of image will change after apply to
a snapshot
with different size.
now, there is a disk_size value in struct QcowSnapshot, i only need to change
the size of current active
image layer when apply a snapshot with different size, and the io request will
be limit in the range of active layer.
and i want my code merged into the master of qemu.
please give me some comments. thanks.
