I think I needed to bit more clear in my explanation. Here is my requirement: At first,I have a guest vm with its virtual disk performing no storage intrusion detection running on top of kvm hypervisor. Then later I create this new VM app that performs the storage intrusion detection functionality again running on top of kvm hypervisor. I run nfs share inside this vm. Once I do this,I need the I/O's that is happening on guest vm to undergo the intrusion detection functionality before writes are performed on the disks. How could I point the image to the NFS share if the guest vm prior didn't had this functionality? And If I do the functionality now,Only NFS-shared partitions could be intercepted.What about the other partition writes occurring at the guest vm? Looking forward to your reply. -- Shiva
