|Subject:||[Qemu-devel] qcow2 resize with snapshots|
|Date:||Fri, 29 Apr 2016 15:55:40 +0800 (CST)|
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.
