I understand syncing virtual disk state with the OS cache is a quite 
challenge to a snapshot tool developers.  However, it is a handy feature 
for the users just want to back up their data in the disks without 
stopping VM.  As  other virtualization solution support this feature,  
we should narrow the gap to attract more users to oVirt.
