Hi All,

I have created a VM with 60GB of disk space.
I have started I/O inside the VM, after sometime when the disk was 4GB full,
I took a snapshot of the disk from UI.

I/O kept continuing and the new image file ( overlay file ) was 15GB in 

Now I deleted the snapshot.
I think this would initiate block-merges.
During this time, my I/O was were slower, till the snapshot delete is 

Its not very slow, but slow.
Is this a known behavior ?

Advance thanks,
Satheesaran S
