From: Sergey Malykhin on 24 Mar 2010 02:10

Hi,

My problem - I have to intercept open&write function calls to .vdi file
when VirtualBox is working to control which sectors of vdi file were
changed, i.e. I need to get 1. what file was open for writing; 2. data
from buffer; 3. size of data; 4. offset in file;

I tryed:
- LD_PRELOAD - not helped

- using fuse - rewrote write call and successfully
intercepted, but fuse is slow.

I have possibilities to patch ext3 or patch inotify.

Is there any better way to do it?

TIA
