[Qemu-devel] kvm binary is deprecated - solved!

[Alexander Binun]

Hi Stefan ,
 Great thanks - your easy trick works! (after I upgraded Ubuntu 13.04 to 13.10).

As for sniffing the traffic between VMs - I have yet one idea and I would 
appreciate your feedback.

The activities at VM that involve modifying data can be divided into the 
following categories:
   1. Talk through network (sending net packets to other hosts)
   2. Disk operations
   3. Memory accesses

In essence memory accesses are always performed BEFORE disk or network 
operations are executed (and the corresponding drivers are employed). For 
example, we prepare data in a buffer and send it into a socket.

That is, a sniffer in the Linux should be put at a kernel driver that makes 
physical memory available to user space. 

Thanks,
   Alex

P.S. I CC  my colleague Dr.Reuven Yagel, a member of the team I am working in.
